Testing and validating existing and widely used SOC models would help to determine attainable C storage in fallows. The Rothamsted C (RothC) model, therefore, was tested using empirical data from improved fallows at Msekera in eastern Zambia. This study (i) determined the effects of nitrogen fixing tree (NFT) species on aboveground organic C inputs to the soil and SOC stocks, (ii) estimated annual net organic C inputs to the soil using the RothC, and (iii) tested the performance of RothC model using empirical data from improved fallows. Soil samples (0\u201320\u00a0cm) were collected from coppicing and non-coppicing fallow experiments in October 2002 for determination of SOC by LECO CHN-1000 analyser. Data on surface litter, maize and weed biomasses, and on weather, were supplied by the Zambia/ICRAF Agroforestry Project. Measured SOC stocks to 20\u00a0cm depth ranged from 32.2 to 37.8\u00a0t\u00a0ha\u22121 in coppicing fallows and 29.5 to 30.1\u00a0t\u00a0ha\u22121 in non-coppicing fallows compared to 22.2\u201326.2\u00a0t\u00a0ha\u22121 in maize monoculture systems. Coppicing fallows accumulated more SOC (680\u20131150\u00a0g\u00a0m\u22122\u00a0year\u22121) than non-coppicing fallows (410\u2013789\u00a0g\u00a0m\u22122\u00a0year\u22121). While treatments with NFTs accumulated more SOC than NFT-free systems, SOC stocks increased with increasing tree biomass production and tree rotation. For food security and C sequestration, coppicing fallows are a potentially viable option. The RothC-26.3 model calculates the effect of annual above- and below-ground plant residue inputs to the soil on total organic C, microbial biomass, and radiocarbon age of the soil over a period ranging from a few years to centuries. As plant residue inputs from roots during plant growth are rarely known, the model is most often run in \u2018inverse\u2019 mode to generate total annual plant residue inputs from known soil, site, and weather data. The model, run in reverse, estimated the annual net organic C inputs required to maintain SOC stocks. Estimates ranged from 2.8 to 6.1\u00a0t\u00a0ha\u22121 in coppicing fallows, 2.2\u20135.7\u00a0t\u00a0ha\u22121 in non-coppicing fallows, and from 1.4 to 2.7\u00a0t\u00a0ha\u22121 in controls. Modelled inputs comprising above- and below-ground organic residues in fallows were 12\u2013104% greater than measured above-ground inputs alone. The model provided a good fit to empirical SOC data in fertilized maize monoculture, and in coppicing and non-coppicing fallows. Modelled inputs for Leucaena, Gliricidia, Senna, Sesbania, and Cajanus closely matched plant C input values estimated in separate studies, suggesting that RothC is giving reasonable simulations of soil C changes under improved fallow conditions in Zambia. However, the DPM/RPM ratio for plant C inputs in fallows was increased from 0.25 to 1.10 to suit their biodegradability characteristics. The RothC model can be used to calculate annual organic C inputs and SOC stocks in improved fallows provided suitable DPM:RPM ratios are used.", "keywords": ["2. Zero hunger", "13.

In cropping systems, soil microorganisms are strongly affected by crop management, including the application of fertilizers. While studies in natural ecosystems have generally found that increased nitrogen (N) inputs decrease microbial biomass, microorganisms in soils under upland crops often benefit from mineral fertilizer input. Paddy rice soils, being flooded for part of the season, are dominated by different carbon (C) and N cycle processes and microbial communities than soils under upland crops. The objective of this study was to explore the effect of fertilizer on soil microorganisms in paddy rice systems in a meta-analysis of the peer-reviewed literature. Across all studies (n\u00a0=\u00a055), the addition of mineral fertilizer significantly increased microbial biomass carbon content (MBC) by 26% in paddy rice soils. Mineral fertilizer applications also increased soil organic carbon content (SOC) by 13%. The higher crop productivity with fertilization likely led to higher organic C inputs, which in turn increased SOC and MBC contents. The time of sampling within a season (pre-plant rice, in-season rice, post-harvest rice, or post-harvest rotational crop) did not significantly affect the response of MBC to mineral fertilizer. The positive effect of mineral fertilizer on MBC content did not differ between cropping systems with continuous rice and systems where paddy rice was grown in rotation with other crops. However, compared with upland cropping systems, the increase in the microbial biomass due to mineral fertilizer application is more pronounced in rice cropping systems, even when rice is grown in rotation with an upland crop. Differences in climate and soil oxygen availability likely explain the stronger response of soil microorganisms to mineral fertilizer input in paddy rice systems. Our analysis suggests that fertilization does not consistently select for specific microbial groups (e.g. gram positive or negative bacteria, fungi, actinomycetes) in paddy rice systems; however, it affects microbial community composition through changes in soil properties. How specific groups of microorganisms respond to mineral fertilization likely depends on environmental factors. Overall, our results suggest that in paddy rice systems the application of inorganic fertilizers increases SOC and MBC contents, both of which are important indicators of soil health.", "keywords": ["2.

Our objectives were to evaluate the effects of nitrogen (N) fertilization and cropping systems on soil organic carbon (SOC) and total N (TN) concentrations and pools. Replicated soil samples were collected in May 2004 to 90\u00a0cm depth from a 23-year-old experiment at the Northwestern Illinois Agricultural Research and Demonstration Center, Monmouth, IL. The SOC and TN concentrations and pools, soil bulk density ( \u03c1 b ) and soil C:N ratio were measured for five N rates [0 (N 0 ), 70 (N 1 ), 140 (N 2 ), 210 (N 3 ) and 280 (N 4 ) kg\u00a0N\u00a0ha \u22121 ] and two cropping systems [continuous corn ( Zea mays L.)

The SOC pool in 0\u201330\u00a0cm depth ranged from 68.4\u00a0Mg\u00a0ha \u22121 for N 0 to 75.8\u00a0Mg\u00a0ha \u22121 for N 4 . Across all N treatments, the SOC pool in 0\u201330\u00a0cm depth for CC was 4.7\u00a0Mg\u00a0ha \u22121 greater than for CS. Similarly, TN concentrations and pools were also significantly affected by N rates. The TN pool for 0\u201330\u00a0cm depth ranged from 5.36\u00a0Mg\u00a0ha \u22121 for N 0 to 6.14\u00a0Mg\u00a0ha \u22121 for N 4 . In relation to cropping systems, the TN pool for 0\u201320\u00a0cm depth for CC was 0.4\u00a0Mg\u00a0ha \u22121 greater than for CS. The increase in SOC and TN pools with higher N rates is attributed to the increased amount of biomass production in CC and CS systems. Increasing N rates significantly decreased \u03c1 b for 0\u201330\u00a0cm and decreased the soil C:N ratio for 0\u201310\u00a0cm soil depth. However, none of the measured soil properties were significantly correlated with N rates and cropping systems below 30\u00a0cm soil depth. We conclude that in the context of developing productive and environmentally sustainable agricultural systems on a site and soil specific basis, the results from this study is helpful to strengthening the database of management effects on SOC storage in the Mollisols of Midwestern U.S.", "keywords": ["2.

In temperate soils, this characteristic has been used as an indicator of quality of soil management. However, few studies have been conducted with this indicator in tropical and subtropical climates or with the main soil orders in these areas. To fill this gap, this study was carried out in a subtropical climate with two of the major Brazilian soil orders, Oxisol and Alfisol, that together account for 63% of Brazilian agricultural soils. This study tested the hypothesis that the CSR is affected by soil order and climate type. The main treatments were soil tillage and different cropping systems in two long-term experiments carried out in the State of Rio Grande do Sul, Brazil. The first experiment, established in 1985, was conducted over a clayey Hapludox (Oxisol) soil. The main plots were treated with one of two tillage systems (conventional tillage \u2013 CT; and no-tillage \u2013 NT). The subplots were treated with one of three cropping systems: (a) continuous crop succession (R0) \u2013 wheat (Triticum aestivum L.)/soybean (Glycine max L. Merrill); (b) winter crop rotation (R1)\u2013wheat/soybean/black oat (Avena strigosa Schreber)/soybean; (c) summer and winter crop rotation (R2) \u2013 wheat/soybean/black oat/soybean/black oat\u00a0+\u00a0common vetch (Vicia sativa L. Walp)/maize (Zea mays L.)/forage radish (Raphanus sativus var. oleiferus Metzg.). The second experiment was established in 1991 over a sandy loam distrophic Paleudalf (Alfisol) soil. Five cropping systems were analyzed under no-till: (a) maize\u00a0+\u00a0jack beans (Canavalia ensiformis DC)/soybean (M/JB); (b) maize/fallow/soybean (M/F); (c) maize/ryegrass (Lolium multiflorum Lam.)\u00a0+\u00a0common vetch/soybean (M/R); (d) maize\u00a0+\u00a0velvet beans (Stizolobium cinereum Piper and Tracy)/soybean (M/VB); and (e) maize/radish oil/soybean (M/FR). The carbon stratification ratio (CSR) was assessed in the 19th and 22nd experimental years for Oxisol and in the 10th and 17th years for Alfisol. This index was calculated through the ratio of SOC stocks in the 0\u20130.05 and 0.05\u20130.15\u00a0m soil layers. The CPI was determined through the ratio of SOC stocks in the 0\u20130.15\u00a0m soil layer in a given treatment compared with native vegetation. Regardless of the soil order, SOC was influenced by C input and the tillage system; there was a positive linear relationship between CSR and CPI. The relationship between the CSR and the carbon pool index (CPI) was used to infer the quality of soil management. Higher CSR and CPI indices were found under treatments with minimum soil disturbance and intensive crop rotation. Lower CSR and CPI values were associated with frequent mobilization and lower crop diversity. These CSR indices sensitively distinguished the intensity of tillage (NT replacing CT) and cropping systems (cover crops replacing winter fallow or crop succession). The CSR values in subtropical soils investigated were lower than those reported for temperate soils. The soil order affected the critical CSR value being lower in the Oxisol than in the Alfisol.

The causes of onset of nitrification in a soil collected under an ashbed which was produced when heaped slash was burned, and for its absence in an unburnt soil, were investigated for an acid forest soil from south-eastern Australia. The occurrence of nitrification in ashbed soils was assessed in laboratory incubations extendig to 151 days to determine if it could be attributed to (a) an increase in pH, (b) an additional supply of P, (c) the removal of chemical inhibitors, and (d) the lack of competition with heterotrophs killed during soil heating. The treatments were: percolated and unpercolated ashbed soil from 0-5 and 5-10 cm depth; unburnt soil from 0-5 cm untreated and with added lime or added P; and burnt and unburnt soil from 5-10 cm depth. In addition, each treatment had an identical where the soil was inoculated with nitrifying garden soil. Compared with the unburnt surface soil (0-5 cm), ashbed soil had higher pH (3.6 units), higher mineral N (3 times) and slightly elevated NaHCO3-extractable P. During 151 days of incubation, microbial respiration in surface ashbed soil, measured as CO2 evolution, initially exceeded the values obtained in unburnt soil but then decreased to only 72% of unburnt soil at the end of the incubation period. In ashbed soil, the microbial biomass N content was low but its C/N ratio was high. Net N mineralization (Nmin) in ashbed soil was not significantly different from unburnt or phosphate fertilized soils (13.1, 14.7 and 17.8 mg N,in kg-' respectively) but was lower than in limed soil (59.3 mg Nmin kg-1). Percolation of surface ashbed soil with distilled water removed high amounts of salts and increased microbial respiration and N mineralization. Inoculation of soils with a slurry from a nitrifying garden soil induced nitrification in every treatment, regardless of their ammonium content, pH or other limiting component. Nitrification was also stimulated in unburnt surface soil on the addition of lime and P. Autotrophic nitriflers were active only in surface ashbed soils and probably in limed soils. P addition promoted heterotrophic nitrification. It was concluded that soil heating reduced competition between autotrophs and heterotrophs for ammonium and that ash supplies nutrients, such as K and Ca which stimulate nitrification. Low pH was not a limiting factor for nitrification but a high pH may promote the establishment of autotrophic nitrifiers.

The examination of 10 plants showed crown and root rot over 100% of the root/crown. Affected plants showed brown necrotic tissues in basal leaves and petiole necrosis. Crown and root tissues were cleaned thoroughly from soil residues under tap water. Portions (about 3 to 5 mm) from crowns and roots were cut and surface disinfected with a water solution of NaClO at 0.5% for 2 min and rinsed in sterile water. The tissue fragments were plated on potato dextrose agar (PDA) amended with 100 mg/liter of streptomycin sulfate and incubated at 25\u00b0C.

The two long-term experiments in Ohio studied were those sited at South Charleston and Hoytville.

The Hoytville clay site is poorly drained, has higher clay content, and higher and more even by distributed antecedent level of SOC in the soil profile than does the South Charleston silt loam soil. No-till increased SOC and N pools in the 0 to 5-cm layer in silt loam soil but had no effect in clay soil. The rate of SOC sequestration in the silt-loam soil under NT was 175 kg C ha -1 y -1 . The silt loam soil had higher SOC and N stratification ratios in NT than in MP and CP treatments, whereas the stratification ratios were low and similar in all treatments in the clayey soil. For both soils, there were no differences between tillage treatments in several soil properties including texture, available water capacity, hydraulic conductivity (K s ), and cation exchange capacity. The NT decreased soil bulk density and pH in the 0 to 15-cm layer in the silt loam soil. The plow till treatments had a small impact on soil aggregation in clayey soil. The decline in water-stable aggregates with reference to NT was no more than one sixth. In the silt loam soil, however, the water-stable aggregates in plow till treatments were merely one third of that in the NT treatment. The historic loss of the SOC pool for 0 to 30-cm depth under agricultural land use was 25 to 35% in silt loam and 19 to 25% in the clayey soil.", "keywords": ["2.

Isoprene is the most abundant biogenic volatile organic compound (BVOC) on Earth, with annual global emissions almost equal to those from methane. Due to its volatile nature and high reactivity, isoprene plays a complex role in atmospheric chemistry and hence, climate. However, very little is known about its biological degradation in the environment. The vast majority of isoprene (500 Tg \uffc2\uffb7y-1) is produced by terrestrial plants and oil palm is considered one of the highest isoprene-producing trees, with estimated emissions of 175 \uffce\uffbcg\uffc2\uffb7g-1 dry leaves \uffc2\uffb7h-1. Oil palm is also a heavily cultivated crop since it is the source of 30% of the vegetable oil in the world and in countries such as Malaysia represents >85% of total agricultural land. The vast expansion of a single crop that emits such high amounts of isoprene have raised serious concerns about its impact on air quality and climate change. We performed DNA Stable Isotope Probing (DNA-SIP) to study the isoprene-degrading community of oil palm trees in a Malaysian plantation and identified novel genera of isoprene-utilising bacteria in both oil palm soils and leaves. isoA amplicon sequencing data also confirmed that oil palm trees harbour a novel diversity of isoA genes, which encode the alpha subunit of the isoprene monooxygenase, a key enzyme in isoprene metabolism. In addition, metagenome assembled genomes (MAGs) were reconstructed from metagenomes from oil palm soil and leaf incubations and analysed to identify isoprene degradation gene clusters in these microorganisms. Finally, analysis of unenriched metagenomes showed that isoA-containing bacteria are more abundant in soils than in the oil palm phyllosphere.

The Indo\uffe2\uff80\uff90Gangetic plain is characterized by intensive agriculture, largely by resource\uffe2\uff80\uff90poor small and marginal farmers. Vast swathes of salt\uffe2\uff80\uff90affected areas in the region provide both challenges and opportunities to bolster food security and sequester carbon after reclamation. Sustainable management of reclaimed soils via resource conservation strategies, such as residue retention, is key to the prosperity of the farmer, as well as increases the efficiency of expensive initiatives to further reclaim sodic land areas, which currently lay barren. After five years of experimentation on resource conservation strategies for rice\uffe2\uff80\uff90wheat systems on partially reclaimed sodic soils of the Indo\uffe2\uff80\uff90Gangetic region, we evaluated changes in different soil carbon pools and crop yield. Out of all resource conservation techniques which were tested, rice\uffe2\uff80\uff90wheat crop residue addition (30% of total production) was most effective in increasing soil organic carbon (SOC). In rice, without crop residue addition (WCR), soils under zero\uffe2\uff80\uff90tillage with transplanting, summer ploughing with transplanting and direct seeding with brown manuring showed a significant increase in SOC over the control (puddling in rice, conventional tillage in wheat). In these treatments relatively higher levels of carbon were attained in all aggregate fractions compared to the control. Soil aggregate sizes in meso (0.25\uffe2\uff80\uff902.0\uffe2\uff80\uff89mm) and macro (2\uffe2\uff80\uff908\uffe2\uff80\uff89mm) ranges increased, whereas micro (< 0.25\uffe2\uff80\uff89mm) fractions decreased in soils under zero\uffe2\uff80\uff90till practices, both with and without crop residue addition. Direct seeding with brown manuring and zero tillage with transplanting also showed an increase of 135% and 95%, respectively, over the control in microbial biomass carbon, without crop residue incorporation. In zero tillage with transplanting treatment, both with and without crop residue showed significant increase in soil carbon sequestration potential. Though the changes in accrued soil carbon did not bring about significant differences in terms of grain yield, overall synthesis in terms of balance between yield and carbon sequestration indicated that summer ploughing with transplanting and zero tillage with transplanting sequestered significantly higher rates of carbon, yet yielded on par with conventional practices. These could be appropriate alternatives to immediately replace conventional tillage and planting practices for rice\uffe2\uff80\uff90wheat cropping systems in the sodic soils of the Indo\uffe2\uff80\uff90Gangetic region.

Climate models predict more extreme weather in Mediterranean ecosystems, with more frequent drought periods and torrential rainfall. These expected changes may affect major process in ecosystems such as mineral cycling. However, there is a lack of experimental data regarding the effects of prolonged drought on nutrient cycling and content in Mediterranean ecosystems.

A 6\uffe2\uff80\uff90year drought manipulation experiment was conducted in a Quercus ilex Mediterranean forest. The aim was to investigate the effects of drought conditions expected to occur over the coming decades, on the contents and concentrations of phosphorus (P) and potassium (K) in stand biomass, and P and K content and availability in soils.

Drought (an average reduction of 15% in soil moisture) increased P leaf concentration by 18\uffc2\uffb72% and reduced P wood and root concentrations (30\uffc2\uffb79% and 39\uffc2\uffb78%, respectively) in the dominant tree species Quercus ilex, suggesting a process of mobilization of P from wood towards leaves. The decrease in P wood concentrations in Quercus ilex, together with a decrease in forest biomass growth, led to an overall decrease (by approximately one\uffe2\uff80\uff90third) of the total P content in above\uffe2\uff80\uff90ground biomass. In control plots, the total P content in the above\uffe2\uff80\uff90ground biomass increased 54\uffc2\uffa0kg\uffc2\uffa0ha\uffe2\uff88\uff921 from 1999 to 2005, whereas in drought plots there was no increase in P levels in above\uffe2\uff80\uff90ground biomass. Drought had no effects on either K above\uffe2\uff80\uff90ground contents or concentrations.

Drought increased total soil soluble P by increasing soil soluble organic P, which is the soil soluble P not directly available to plant capture. Drought reduced the ratio of soil soluble inorganic P\uffc2\uffa0:\uffc2\uffa0soil soluble organic P by 50% showing a decrease of inorganic P release from P bound to organic matter. Drought increased by 10% the total K content in the soil, but reduced the soil soluble K by 20\uffc2\uffb74%.

Drought led to diminished plant uptake of mineral nutrients and to greater recalcitrance of minerals in soil. This will lead to a reduction in P and K in the ecosystem, due to losses in P and K through leaching and erosion, if the heavy rainfalls predicted by IPCC (Intergovernmental Panel on Climate Change) models occur. As P is currently a limiting factor in many Mediterranean terrestrial ecosystems, and given that P and K are necessary for high water\uffe2\uff80\uff90use efficiency and stomata control, the negative effects of drought on P and K content in the ecosystem may well have additional indirect negative effects on plant fitness.

Among the current environmental concerns for forests of the eastern United States is nitrogen (N) saturation, a result of excessive inputs of N associated with acidic deposition. We studied nutrient responses on N-treated and untreated watersheds of the Fernow Experimental Forest, West Virginia, to test for evidence of N saturation on the treated watershed. The watersheds were WS7 (23-year-old even-aged control), WS4 (mature mixed-aged control), and WS3 (23-year-old even-aged treatment). WS3 has received aerial applications of (NH4)2SO4 from 1989 to the present (a total of 4 years for the study period) at 3\uffe2\uff80\uff82\uffc3\uff97\uffe2\uff80\uff82ambient inputs of N and S (54 and 61\uffe2\uff80\uff82kg\uffe2\uff80\uffa2ha\uffe2\uff88\uff921\uffe2\uff80\uffa2year\uffe2\uff88\uff921, respectively). Base-flow stream samples were collected weekly from each watershed and analyzed for NO3\uffe2\uff88\uff92 and Ca2+. Mineral soil was incubated in situ, placed in bags, and buried about every 30 days during the growing season in each of seven sample plots within each watershed. Moist samples of soil from the bags were analyzed for extractable NH4+ and NO3\uffe2\uff88\uff92. In addition, forest floor material and leaves of an herbaceous species (Violarotundifolia Michx.) from each plot were analyzed for N and other nutrients. Violarotundifolia was present on all 21 plots and used as an additional indicator of N availability and soil fertility. Foliage tissue was sampled from overstory tree species (Liriodendrontulipifera L., Prunusserotina Ehrh., Betulalenta L., and Acerrubrum L.) from WS3 and WS7 and analyzed for nutrient content. Results from the 1993 growing season showed few, if any, differences among watersheds for (1) N content and C/N ratio of the mineral soil and forest floor and (2) relative proportion of NH4+ and NO3\uffe2\uff88\uff92 produced in the buried bags. Nitrification rates were equally high in soils of all watersheds; N concentrations were significantly higher in foliage tissue of overstory tree species and of V. rotundifolia in the treatment versus control watersheds; plant tissue Ca was significantly lower for the treatment watershed than for the control watersheds. Our results support the conclusions of earlier studies that high amounts of ambient N deposition have brought about N saturation on untreated watersheds at the Fernow Experimental Forest. This is suggested by minimal differences among watersheds in N mineralization and nitrification and soil and forest floor N. However, aggravated N saturation on our treated watershed can be seen in differences in plant tissue nutrients among watersheds and streamflow data, indicating increased losses of NO3\uffe2\uff88\uff92 with accompanying losses of Ca2+ in response to further N additions to a N-saturated system.

Understanding the impact of crop rotation and residue management in grass seed production systems on soil quality and, in particular soil C dynamics, is critical in making long\uffe2\uff80\uff90term soil management decisions supporting farm sustainability. The effects of a 6\uffe2\uff80\uff90yr rotation and residue management (high vs. low residue) on soil quality were investigated at three locations in Oregon, each contrasting in soil drainage classification. The crop rotations were continuous perennial grass seed production, grass/legume seed production, and grass/legume/cereal seed production. The grass species grown at each location were different and represented those most commonly produced in each environment; perennial ryegrass (Lolium perenne L.), tall fescue [Schedonorus phoenix (Scop.) Holub], and creeping red fescue (Festuca rubra L.). All three grass seed crop rotations and residue methods maintained high soil quality in conventional or direct seeded soils, but under some situations, soil quality was higher with continuous grass rotation and high residue. Data suggest that straw removal for value\uffe2\uff80\uff90added use, like bioenergy production, can be accomplished in the Pacific Northwest Marine climate without appreciably affecting soil quality. Furthermore, grass seed cropping systems play an important role in soil C storage and enhancement, a valuable ecosystem service in this region where grass seed is produced on land that is not suitable for production of conventional crops that require better\uffe2\uff80\uff90drained soil. We conclude that by nature perennial grass seed crops promote high soil fertility and enriched soil C pools and consequently contribute to the tolerance of these systems to the use of less conservation\uffe2\uff80\uff90oriented crop management methods at times when crop loss could be potentially high. This attribute provides producers greater latitude in selecting soil and crop management options to address issues of soil fertility, pest, weed, or seed certification to minimize economic crop yield losses.

However, few programs have addressed the functional ecological equivalence of man-made marshes and their natural counterparts. This study addresses structural and functional interactions in a man-made and two natural marshes. This was done by integrating substrate characteristics and marsh utilization by organisms of two trophic levels. Sediment properties, infaunal community composition, andFundulus heteroclitus marsh utilization were compared for a man-madeSpartina salt marsh (between ages 1 to 3 yr) in Dills Creek, North Carolina, and adjacent natural marshes to the east and west. East natural marsh and planted marsh sediment grain-size distributions were more similar to each other than to the west natural marsh due to shared drainage systems, but sediment organic content of the planted marsh was much lower than in either natural marsh. This difference was reflected in macrofaunal composition. Natural marsh sediments were inhabited primarily by subsurface, deposit-feeding oligochaetes whereas planted marsh sediments were dominated by the tube-building, surface-deposit feeding polychaetesStreblospio benedicti andManayunkia aestuarina. Infaunal differences were mirrored inFundulus diets. Natural marsh diets contained more detritus and insects, because oligochaetes, though abundant, were relatively inaccessible. Polychaetes and algae were major constituents of the planted marshFundulus diet. Though naturalmarsh fish may acquire a potentially less nutritive, detritus-based diet relative to the higher animal protein diet of the planted marsh fish,Fundulus abundances were markedly lower in the planted marsh than in the natural marshes, indicating fewer fish were being supported. LowerSpartina stem densities in the planted marsh may have provided inadequate protection from predation or insufficient spawning sites for the fundulids. After three years, the planted marsh remained functionally distinct from the adjacent natural marshes. Mitigation success at Dills Creek could have been improved by increasing tidal flushing, thereby enhancing, access to marine organisms and by mulching withSpartina wrack to increase sediment organic-matter content and porosity.

Rising concerns about greenhouse gases, increased fuel prices, and the potential for new high value agricultural products have raised interest in the use of maize stover for bioenergy production. However, residue harvest must be weighed against potential negative impacts on soil quality. This study, conducted in Chazy, NY, evaluated the long\uffe2\uff80\uff90term effects of 32 yr of maize (Zea maysL.) stover harvest vs. stover return on soil quality in the surface layer (5\uffe2\uff80\uff9366 mm) under plow till (PT) and no\uffe2\uff80\uff90till (NT) systems on a Raynham silt loam (coarse\uffe2\uff80\uff90silty, mixed, active, nonacid, mesic Aeric Epiaquept) using physical, chemical, and biological soil properties as soil quality indicators. Twenty\uffe2\uff80\uff90five soil properties were measured, including standard chemical soil tests, aggregate stability (WSA), bulk density, (\uffcf\uff81b) penetration resistance (PR), saturated hydraulic conductivity (Ks), infiltrability (Infilt), several porosity indicators (aeration pores(PO > 1000), soil water potential = \uffce\uffa8 > \uffe2\uff88\uff920.36 kPa; air\uffe2\uff80\uff90filled pores at field capacity (PO > 30), \uffce\uffa8 > \uffe2\uff88\uff9210kPa; available water capacity (AWC), \uffe2\uff88\uff921500 < \uffce\uffa8 < \uffe2\uff88\uff9210 kPa), total organic matter (OM), parasitic (Nemparasitic) and beneficial nematode (Nembeneficial) populations, decomposition rate (Decomp), potentially mineralizable N (PMN) and easily extractable (EEG) and total glomalin (TG). Only eight indicators were adversely affected by stover harvest, and most of these effects were significant only under NT. Almost all indicators affected by stover removal were affected equally or more adversely by tillage. A total of 15 indicators were adversely affected by tillage. Results of this study suggest that, on a silt loam soil in a temperate climate, long\uffe2\uff80\uff90term stover harvest had lower adverse impacts on soil quality than long\uffe2\uff80\uff90term tillage.

Currently, BC types most under investigation are those obtained from organic matter (OM) of plant origin. As great amounts of manure solids are expected to become available in the near future, thanks to the development of technologies for the separation of the solid fraction of animal effluents, processing of manure solids for BC production seems an interesting possibility for the recycling of OM of high nutrient value. The aim of this study was to investigate carbon (C) sequestration and nutrient dynamics in soil amended with BC from dried swine manure solids. The experiment was carried out in laboratory microcosms on a silty clay soil. The effect on nutrient dynamics of interaction between BC and fresh digestate obtained from a biogas plant was also investigated to test the hypothesis that BC can retain nutrients. A comparison was made of the following treatments: soil amended with swine manure solids (LC), soil amended with charred swine manure solids (LT), soil amended with wood chip (CC), soil amended with charred wood chip (CT), soil with no amendment as control (Cs), each one of them with and without incorporation of digestate (D) for a total of 10 treatments. Biochar was obtained by treating OM (wood chip or swine manure) with moisture content of less than 10% at 420\u00b0C in anoxic conditions. The CO2-C release and organic C, available phosphorus (P) (Olsen P, POls) and inorganic (ammonium+nitrate) nitrogen (N) (Nmin) contents at the start and three months after the start of the experiment were measured in the amended and control soils. After three months of incubation at 30\u00b0C, the CO2-C emissions from soil with BC (CT and LT, \u00b1D) were the same as those in the control soil (Cs) and were lower than those in the soils with untreated amendments (CC and LC, \u00b1D). The organic C content decreased in CT and LT to a lesser extent than in CC and LC. In soils with D (+D), the CO2-C emissions were equal to or higher than those in soils without (-D). The Nmin content increased in all treatments; the POls content decreased in the +D treatments. The incorporation of BC into soil, by reducing CO2 emissions, actually contributes to C sequestration without modifying N availability for crops. For a given N content, the BC from swine manure solids supplies much more P than the non-treated OM and, therefore, represents an interesting source of P for crops.", "keywords": ["2.

&lt;p&gt;Monitoring CO&lt;sub&gt;2&lt;/sub&gt; emissions originating from urban areas has become a necessity to support sustainable urban planning strategies and climate change mitigation efforts. Integrative decision support, where net effects of various emission/sink components are considered and compared, is now an increasingly relevant part of urban planning processes. The current emission inventories rely on indirect approaches that use fuel and electricity consumption statistics for determining CO&lt;sub&gt;2&lt;/sub&gt; emissions. The consistency of such approaches is questionable and they usually neglect the contribution of the biogenic components of the urban carbon cycle (i.e. vegetation, soil). Moreover, their spatial and temporal scales are restricted because consumption statistics are often available in coarse spatial scales (national, provincial/state, municipal) and usually scaled down using proxy data (e.g. population density) to city-scale annual estimates. The diFUME project (https://mcr.unibas.ch/difume/) is developing a methodology for mapping and monitoring the actual urban CO&lt;sub&gt;2&lt;/sub&gt; flux at optimum spatial and temporal scales, meaningful for urban design decisions. The goal is to develop, apply and evaluate independent models, capable to estimate all the different components of the urban carbon cycle (i.e. building emissions, traffic emissions, human metabolism, photosynthetic uptake, plant respiration, soil respiration), combining mainly Eddy Covariance (EC) with Earth Observation (EO) data. EC provides continuous in-situ measurements of CO&lt;sub&gt;2&lt;/sub&gt; flux at the local scale. Processing, analysis and interpretation of urban EC measurements is challenging due to the inherent spatial complexity of CO&lt;sub&gt;2&lt;/sub&gt; source and sink configurations of the urban structure. The diFUME methodology is using multiple EO datasets to achieve multi-scale monitoring of urban cover, morphology and vegetation phenology in order to characterize the urban source/sink configurations and parameterize turbulent flux source area models. Such combination of EC and EO provides enhanced interpretation of the measured CO&lt;sub&gt;2&lt;/sub&gt; flux, analysis of its controlling factors and therefore the potential of fine scale mapping and monitoring. The diFUME methodology is being developed and applied in the city of Basel, exploiting the available long-term database (&gt; 15 years) of urban EC measurements. The first results highlight the potential of EO-derived geospatial data to interpret the complexity of urban EC measurements. Seasonal and land cover related trends in the EC-measured CO&lt;sub&gt;2&lt;/sub&gt; flux are recognized, while the use of environmental, census and mobility datasets are increasing the interpretation capabilities and the modelling potential of the urban CO&lt;sub&gt;2&lt;/sub&gt; flux patterns.&lt;/p&gt;

&lt;p&gt;Sustainable agriculture should be based on management practices that improve resource usage efficiency and minimize harmful impacts on the environment while maintaining and stabilizing crop production. Both tillage and irrigation can have a great influence on hydrological processes within agroecosystems. However, it remains difficult to directly assess the effect of practices on water fluxes which has been mainly indirectly quantified by complex numerical modelling methods in the past. Therefore, the objective of the study was to use a space for time concept and measure oxygen and hydrogen isotopes (&amp;#948;&lt;sup&gt;18&lt;/sup&gt;O, &amp;#948;&lt;sup&gt;2&lt;/sup&gt;H) in the pore water of soil profiles as well as moisture contents for quantifying the soil water balance and fluxes. Covering all combinations, soil profiles and isotope analysis was performed for 16 sites planted with winter wheat and managed with different tillage (conventional tillage (CT), reduced tillage (RT), minimal tillage (MT), and no-tillage (NT)) and irrigation systems (hose reel boom irrigation with nozzles (BI), sprinkler irrigation (SI), drip irrigation (DI) and no irrigation (NI)). The results indicated that the more intense the tillage, the lower the water content. Among the irrigation systems, DI had the highest average water content. Tracing the minimum in the isotopic composition of the pores water within the depth profiles showed a deeper percolation of water in the CT fields, which indicates higher water flow velocity. Considering both water content and differences in water flow velocities resulted in water fluxes ranging from 90 to 151 mm yr&lt;sup&gt;-1&lt;/sup&gt;. The losses due to evapotranspiration varied between 57 and 80%. The resulting evapotranspiration within tillage and irrigation variants decreased in the order RT&gt;CT&amp;#8776;MT&gt;NT, and SI&gt;BI&gt;DI&gt;NI. Thus, the method revealed that the lower water content in CT fields is a consequence of deeper water infiltration. Moreover, irrigation water contributed mostly to evapotranspiration, and drip irrigation showed the lowest evapotranspiration losses among irrigation systems. This study demonstrated that water stable isotopes can be used as indicators and are a promising method to quantify water fluxes in agricultural fields with great potential for evaluating management practices.&lt;/p&gt;

Most of the climate scenarios predict increased water scarcity in arid areas, such as Hungary. However, the irrigated area in Hungary covers 2% of agricultural land, mostly with outdated irrigation technology. The aim of the research was to develop the basis of a variable rate irrigation for water-saving precision sprinkler irrigation system on an arable area (85 ha) which is located in the reference area of the Tisza Riven Basin. There is limited available water resources at the site, therefore alternative water sources utilization system was set up for irrigation to adapt to climate change and reduce fertilizers. The basis of the alternative water resources are excess water, treated wastewater, biogas fermentation sludge which is collected in a water reservoir with 114000 m3 capacity. For proper irrigation scheduling, heterogeneity of topography, hydrological, soil and crop conditions has to be explored and monitored. Therefore physically-based modelling of the water balance and remote sensing-based surplus water and &#160;vegetation status surveying are tested to use for accurate irrigation scheduling.Shallow groundwater and/or soil compaction can also contribute to excess inland water. This may occur even if there are drought periods in a year (e.g. in the Pannonian region), resulting in spots with a low crop yield. A LiDAR-based digital elevation model was found to provide appropriate data to identify sites affected by excess inland water. The spots identified can be used as spatial input data to compile a variable rate irrigation prescription map for imposing reduced (or zero) irrigation at areas more vulnerable to the occurrence of excess inland water. The water balance was also assessed for sites with physically-based models. Hydrus was used to model soil moisture changes at the Hungarian case study site.A model concept for crop evapotranspiration estimation was also developed based on vegetation indices calculated from satellite imagery. Several combinations of sensors and remote sensing products were tested to use in ETc modelling potentially. This approach was tested both at the Hungarian case study sites. Remote sensing-based analysis of crop evapotranspiration, combined with physically-based modelling, appears to be a promising method in water balance modelling of maize fields, especially if these fields are in summer when the crop is fully developed. However, the remotely sensed information verification is essential for the proper utilization of the remote sensing data in ETc modelling and predicting the spatio-temporal dynamics of crop yield, evapotranspiration, and irrigation demands.There is a need further benchmark scenarios to improve both physically-based models and satellite-based crop evapotranspiration models to achieve more accurate and valid simulations.The abstract was funded by European Union&#8217;s Horizon 2020 &#8220;WATERAGRI Water retention and nutrient recycling in soils and steams for improved agricultural production&#8221; research and innovation programme under Grant Agreement No. 858375.

Their effectiveness has been widely tested (Malus\u00e0 et al., 2016). However, little is known about the effect of bioinoculants on microbial assemblages in non-rhizospheric soil. A sudden artificial introduction of a fungal species in soil could theoretically impact the biodiversity of local microbial communities and lead to changes in nutrient availability (van Elsas et al., 2012). We assessed the impact of a competitive fungal inoculum, the globally-used biofertiliser Trichoderma afroharzianum T22, on soil microcosms to understand 1) to what extent the native microbial community richness and relative abundance are influenced by a fungal strain introduced to soil; 2) whether microbial taxa are resilient to the disturbance caused by the fungus; 3) how far the bioinoculant impacts the soil microorganisms functions. We used bacterial 16S rRNA gene amplicon sequencing (Illumina) and a shotgun metagenomic analysis (Oxford Nanopore Sequencing) to analyse the microbial communities in bioreactors after seven weeks of incubation with and without the fungus. The presence of the fungus had a negative impact on the abundance of some groups of bacteria, such as the genus Pseudomonas, and it stimulated the presence of species metabolically linked to the fungus, including chitin degrading Chitinophagaceae. In conclusion, the results suggest that more than an impact on bacteria's overall biodiversity, the fungus has favoured some groups at the expense of others, even creating new food webs and trophic niches.

The Horizon Europe (HE) Mission \u201cA Soil Deal for Europe\u201d aims to accelerate the transition to sustainable soil and land management and healthy soils through an am-bitious transdisciplinary research and innovation (R&I) programme, largely based on actor engagement, Liv-ing Labs and Lighthouses. The H2020 Soil Mission Support (SMS) project supported the implementation of the HE Mission, and aimed to improve the coordination of R&I on sustainable soil and land management. Through a co-creation process together with actors, SMS collated available knowledge, actors R&I needs and identified R&I gaps that need to be addressed for successful transition towards sustainable soil and land management.
The first step was to identify existing R&I knowledge through a keyword-based analysis of scientific literature published and peer reviewed, related to sustainable soil and land management. The literature analysis ad-dressed the full range of societal challenges, soil health objectives, land use types and knowledge domains necessary to capture the socio-ecological complexity of soil health. Covering some 15,700 scientific articles, this literature analysis represents the current peer reviewed knowledge stock on sustainable soil and land management. A textual analysis using the digital platform CorTexT was undertaken to explore the identified literature and submitted to project consortium internal experts, who analysed and processed the collected information of their respective area of expertise (Annex III). The literature analysis revealed that the societal challenges \u201creduce soil degradation\u201d and \u201cimprove disaster control\u201d have been studied extensively. Con-versely, the societal challenges \u201cmitigate land take\u201d and \u201cincrease biodiversity\u201d and the knowledge domains \u201cscience-based policy support\u201d and \u201cawareness, training & education\u201d are less discussed. Factsheets present-ing the results of the literature analysis per societal challenge were developed and can be found in Annex VIII. Note that as the key-word based literature search was limited to Scopus-indexed scientific journals, other publishing formats such as conference papers, books, book chapters, non-digitalized articles, grey literature, reports, patents, etc., may be underrepresented or not included in the used data base. The exclusive use of Scopus-indexed scientific articles provided quality insurance of the material through the publication peer-review system. Nonetheless, important documents and knowledge have been incorporated by the consor-tium experts when analysing the collected literature.
The second step was to consult actors through online workshops and surveys in order to gain a practice-oriented \u2018real-life\u2019 picture of current knowledge and R&I needs for swift implementation of sustainable soil and land management. This step was seen as complementary of the published and peer-reviewed literature.
Finally, after exploring our stocktaking of R&I from existing knowledge evidenced by literature review and the actor\u2019s knowledge needs identified from actor consultations, we identified R&I gaps. The main knowledge gaps across all Mission Objectives were of socio-economic nature: drivers and causes of land degradation, knowledge management, governance and policies for inciting improved management, and interaction with other sectors are not sufficiently understood. Second, the HE Missions\u2019 focus on improving soil literacy was supported by the literature analysis and by the actor consultation, which both revealed knowledge gaps re-lated to education and capacity building in all land use types and domains affecting soil health: production, consumption, trade, policy and governance. Thirdly, there is a gap in the long-term implementation of a new mode of knowledge co-design, where researchers and practitioners together develop solutions for sustaina-ble soil and land management in a real-world context. The HE Missions\u2019 focus on Living Labs and Lighthouses has the potential to close this gap. Finally, there is a need to define several concepts (e.g. soil health, soil degradation, footprint). Such definitions should be shared and will be a basis to identify relevant indicators and respective thresholds, and to develop guidelines to support monitoring programmes in order to translate knowledge into evidence for decision making.

However, this practice causes serious soil depletion and N loss in the traditional wheat cropping system in the Loess Plateau of China. Growing summer legumes as the green manure (GM) crop is a viable solution because of its unique ability to fix atmospheric N 2 . Actually, little is known about the contribution of GM N to grain and N utilization in the subsequent crop. Therefore, we conducted a four-year field experiment with four winter wheat-based rotations (summer fallow-wheat, Huai bean\u2013wheat, soybean\u2013wheat, and mung bean\u2013wheat) and four nitrogen fertilizer rates applied to wheat (0, 108, 135, and 162\u00a0kg\u00a0N/ha) to investigate the fate of GM nitrogen via decomposition, utilization by wheat, and contribution to grain production and nitrogen economy through GM legumes. Here we showed that GM legumes accumulated 53\u201376\u00a0kg\u00a0N/ha per year. After decomposing for approximately one year, more than 32\u00a0kg\u00a0N/ha was released from GM legumes. The amount of nitrogen released via GM decomposition that was subsequently utilized by wheat was 7\u201327\u00a0kg N/ha. Incorporation of GM legumes effectively replaced 13\u201348% (average 31%) of the applied mineral nitrogen fertilizer. Additionally, the GM approach during the fallow period reduced the risk of nitrate-N leaching to depths of 0\u2013100\u00a0cm and 100\u2013200\u00a0cm by 4.8 and 19.6\u00a0kg\u00a0N/ha, respectively. The soil nitrogen pool was effectively improved by incorporation of GM legumes at the times of wheat sowing. Cultivation of leguminous GM during summer is a better option than bare fallow to maintain the soil nitrogen pool, and decrease the rates required for N fertilization not only in the Loess Plateau of China but also in other similar dryland regions worldwide.", "keywords": ["2.

We have proposed the water management based on soil redox potential (Eh) named \u2018Eh control\u2019, and demonstrated the effectiveness of Eh control in decreasing CH4 emission in pot experiments. The objective of the present study was to consider the practicability of Eh control under field conditions. Two-year experiments were carried out in a paddy field at the Agricultural and Forestry Research Center, University of Tsukuba, Japan in 2003 and 2004. Experimental factors were water management and rice (Oryza sativa L., cultivar: Koshihikari) straw treatment. Two methods of water management during rice growing period were continuous flooding and Eh control. For Eh control, drainage was carried out whenever the soil Eh decreased to \u2212150\u00a0mV, and flooding was carried out whenever the soil Eh increased to 0\u00a0mV in 2003 and 100\u00a0mV in 2004. Two methods of rice straw treatment were application and removal in the preceding winters of all straw harvested. The CH4 flux was measured by a closed chamber method and the total emission during the growing period was estimated. Rice grain and straw yields were examined by a quadrat sampling method. The yield component was analyzed only in 2004. The total CH4 emission was decreased by Eh control to 36% of continuous flooding on the 2-year average. Although straw application hastened the decrease in soil Eh when compared with straw removal, it did not affect the total CH4 emission. Rice grain and straw yields were not affected by the experimental factors. However, yield component analysis showed that Eh control increased the number of panicles per hill and resulted in increased brown rice yield. Straw application also increased the number of panicles per hill, but did not affect brown rice yield. Consequently, the present study demonstrates the practicability of Eh control under the field conditions on an experimental level. Two important suggestions were obtained from the above results. One is that Eh control decreases CH4 emission to a minimum level according to the range of soil Eh determined. Another is that it may be possible to change the range of soil Eh to a more positive value that will decrease CH4 emission more and increase rice grain yield.", "keywords": ["2. Zero hunger", "13.

A representative composite water sample collected from the Danube River was divided into 12 subsamples, and processed following two different methods, which differed in MP isolation procedures, the optical substrate utilized for the chemical imaging, and the detection limit of the spectroscopic instruments. The first instrument had a nominal pixel resolution of 5.5\u00a0\u03bcm, while the second had a nominal resolution of 25\u00a0\u03bcm.

Looking deeper into the steps of the methods showed that the MP isolation procedure contributed slightly to the difference in the result. However, the variability between individual samples was larger than the difference caused by the methods. Somewhat sample-dependent, the use of two different substrates (zinc selenide windows versus Anodisc filters) caused a substantial difference between results. This was due to a higher tendency for particles to agglomerate on the Anodisc filters, and an 'IR-halo' around particles on ZnSe windows when scanning with \u03bcFTIR. Finally, the \u03bcFTIR settings and nominal resolution caused significant differences in identifying MP size and mass estimate, which showed that the smaller the pixel size, the more accurately the particle boundary can be defined.

This study explores a novel approach that combines soil recovery with biofuel production, presenting a strategy that addresses the increasing demand for biofuels while sidestepping the food\uffe2\uff80\uff93fuel debate. It also introduces an innovative method for recovering heavy metals from soils through their translocation into the solid product of the conversion process. Phytoremediation trials were conducted under real field conditions, and the thermochemical conversion of the harvested biomass was carried out at lab scale. Field trials took place in 2021\uffe2\uff80\uff932023 in Lithuania and Serbia. In Serbia, the contamination primarily involved heavy metals, whereas the Lithuanian site was predominantly contaminated with hydrocarbons from petroleum products. The harvested biomass underwent pretreatment and was then used as feedstock for conversion into high\uffe2\uff80\uff90energy carriers. The conversion products were evaluated for their potential to substitute fossil fuels. Finally, the value chain, encompassing key stakeholders and factors impacting the profitability of this approach, was established, and initial estimates were made regarding the size of individual cost components.Increasing temperatures and a reduction in the frequency and severity of freezing events have been linked to species distribution shifts. Across the globe, mangrove ranges are expanding toward higher latitudes, likely due to diminishing frequency of freezing events associated with climate change. Continued warming will alter coastal wetland plant dynamics both above\uffe2\uff80\uff90 and belowground, potentially altering plant capacity to keep up with sea level rise. We conducted an in situ warming experiment, in northeast Florida, to determine how increased temperature (+2\uffc2\uffb0C) influences co\uffe2\uff80\uff90occurring mangrove and salt marsh plants. Warming was achieved using passive warming with three treatment levels (ambient, shade control, warmed). Avicennia germinans, the black mangrove, exhibited no differences in growth or height due to experimental warming, but displayed a warming\uffe2\uff80\uff90induced increase in leaf production (48%). Surprisingly, Distichlis spicata, the dominant salt marsh grass, increased in biomass (53% in 2013 and 70% in 2014), density (41%) and height (18%) with warming during summer months. Warming decreased plant root mass at depth and changed abundances of anaerobic bacterial taxa. Even while the poleward shift of mangroves is clearly controlled by the occurrences of severe freezes, chronic warming between these freeze events may slow the progression of mangrove dominance within ecotones.

The degree of stratification, or stratification ratio (SR), can be used as an indicator of soil quality because surface organic matter is essential to erosion control, water infiltration, and the conservation of nutrients. In the semiarid regions of the Mediterranean which are devoted to rain-fed crop production, soil has low organic carbon content because of the high mineralization rates of soil organic matter and the lack of crop residue after periods of drought. Twenty-year effects (1985\u20132006) of tillage systems on soil organic carbon (SOC) stratification were studied in a Vertic Luvisol with a loam texture. SOC was expressed in carbon concentration (Cc) and in equivalent soil mass (esm). The tillage treatments used were conventional tillage (CT), minimum tillage (MT), and no-tillage (NT). These treatments were under winter wheat (Triticum aestivum L.), vetch (Vicia sativa L.) and pea (Pisum sativum L.) rotation (W-VP). Similarly, several stratification ratios (SRs) were assessed as indicators of SOC's time evolution. Before the start of the experiment the crop rotation was cereal-fallow (C-F). In each treatment and replication four soil layers of the same thickness (10\u00a0cm) were sampled to obtain soil bulk density (BD) and Cc. After 20 years the study revealed that the adoption of a W-VP rotation was at least as important as the shift from CT to NT in the increase of stocked SOC in the soil profile. This last treatment was the tillage system with the highest SOC, whereas no significant differences were encountered between MT and CT. The average SOC was 14% higher in NT than in MT and CT. This trend has been systematically observed practically since 1996 to the present in all treatments. The steady state of SOC sequestration was reached after 11 years of starting the experiment in NT and 12 years in CT and MT. SOC, expressed as Cc and esm, showed the highest stratification in NT, second highest in MT and lowest in CT. In NT, stocked SOC increased from 1996 to 2005 in the top layer but it declined systematically in the bottom layer.", "keywords": ["2.

This decrease may be mitigated by the addition of exogenous organic matter (EOM). The aim of this study was to assess the effect of EOMs, including compost from manure, slurry, and straw (Ag); industrial organic compost from sewage sludge (Ra); animal meal from animal by-products (Mb); and digestate from a biogas fry factory (Dg) on soil thermal conductivity, heat capacity, thermal diffusivity, water content, and bulk density in the top (0\u201315-cm) layer of two soils in Poland and the Czech Republic. Irrespective of EOM type, the total yearly nitrogen application rate being 200\u00a0kg N\u00a0ha\u22121 (100%) was from a given EOM at the rates 0, 50, 75, and 100% and the remaining parts from the mineral fertilizer. The study was conducted in 2013\u20132014 in Poland (Braszowice) and the Czech Republic (Puste Jakartice) on loam silt and clay silt loam, respectively, as part of a cross-border cooperation project. The soil properties were examined using classical descriptive statistics, semivariograms, and kriging-interpolated maps. Analysis of linear regressions (trends) showed that the EOM application rate influenced (positively or negatively) the soil properties in most measurement occasions. The variability of all soil properties was low and medium (coefficient of variation 7.3\u201334%). Geostatistical analysis indicated that the spatial dependence (C0/(C0\u2009+\u2009Cs)) of the soil properties on the EOM-amended plots was very strong or moderate. The maps revealed that the heterogeneity and degree of patch fragmentation were greater for thermal conductivity and heat capacity than for thermal diffusivity, water content, and bulk density. In general, all the soil properties were spatially more variable in the Braszowice than Puste Jakartice soil and in spring than autumn in both sites. The spatial analysis and maps enhance the comprehensive understanding of changes in soil thermal properties in response to EOM application. Suitability of the results from the field experiments in models predicting some thermal properties based on soil bulk density and water content in relation to EOM addition was indicated. Expressing the amount of EOMs added using the organic carbon content basis (% kg OC/kg of soil) instead of the nitrogen content basis allowed identifying areas on the kriging-interpolated maps where the distribution of soil thermal properties resembled that of soil organic carbon content, water content, and bulk density. Thus, the effect of EOMs on soil thermal properties is considered along with changes in soil water content and bulk density. The results will be helpful in forecasting effects of exogenous organic matter on the soil thermal properties affecting surface-energy partitioning, temperature distribution in soil, and plant growth.", "keywords": ["2.

In this study, a field fertilization experiment was conducted in a light sandy loam soil from the Huang-Huai-Hai Plain of China to determine the variation in soil available P, P composition and phosphatase activities with 23 years of continuous application of maize straw or cattle manure in combination with chemical fertilizers at the depth of 0\u201320\u00a0cm, with special attention paid to their relationships. The experiment was arranged in a randomized block design with three replications for each treatment, including the unfertilized control (CK), chemical nitrogen (N) with phosphorus (P) and potassium (K) (NPK), NPK plus maize straw (NPKS), and NPK plus cattle manure (NPKM). Results indicated that all fertilization treatments significantly increased soil P concentration and crop yields. Among the fertilization treatments, NPKM treatment showed the significantly highest total P and available P concentrations, while no significant difference in either wheat or maize yield between NPK, NPKS and NPKM treatments was found. Compared to the application of chemical NPK fertilizers alone, the NPKS treatment significantly increased soil organic P, pyrophosphate and orthophosphate concentrations, as well as soil phosphatase activities. The increase in orthophosphate concentration under the NPKS treatment may be associated with the hydrolysis of organic P and pyrophosphate catalyzed by acid phosphomonoesterase (AcP), phosphodiesterase (PD) and inorganic pyrophosphatase (IPP), which was conducive to keeping soil available P concentration under NPKS treatment at an appropriate level that could not only satisfy crop P demand but also have no negative impacts on the environment. However, the increase of orthophosphate and available P concentrations under NPKM treatment may be primarily related to the manure P inputs, and although NPKM treatment significantly increased soil inorganic P concentration in comparison to other fertilization treatments, it also increased the risk of P leaching. Overall, from the perspective of P nutrient management, our results suggest that NPKS treatment might be an effective long-term fertilization practice in the light sandy loam soil of Huang-Huai-Hai Plain of China.", "keywords": ["2.

While producing renewable energy from biomass is necessary, impacts of harvesting corn stover on soil organic carbon (SOC) sequestration, agricultural productivity, and environmental quality must be also carefully and objectively assessed. We conducted a 2 1/2 year study of stover management in long-term (N8 yr) no-tillage (NT) continuous corn systems under three contrasting soils in Ohio to determine changes in SOC sequestration, CO2 emissions, soil physical properties, and agronomic productivity. These measurements were made on a Rayne silt loam (RSL) (fine-loamy, mixed, active, mesic Typic Hapludult) with 6% slope, Celina silt loam (CSL) (fine, mixed, active, mesic Aquic Hapludalfs) with 2% slope, and Hoytville clay loam (HCL) (fine, illitic, mesic Mollic Epiaqualfs) with b1% slope. Stover treatments consisted of removing 0, 25, 50, 75, and 100% of corn stover following each harvest. At the start of the experiment in May 2004, these percentages of removal corresponded to 5, 3.75, 2.5, 1.25, and 0M g ha \u22121 yr \u22121 of stover left on the soil surface, respectively. Annual stover removal rate of N25% reduced SOC and soil productivity, but the magnitude of impacts depended on soil type and topographic conditions. Stover removal rate of 50% reduced grain yield by about 1.94 Mg ha \u22121 , stover yield by 0.97 Mg ha \u22121 , and SOC by 1.63 Mg ha \u22121 in an unglaciated, sloping, and erosion-prone soil (Pb0.05). The initial water infiltration rates were significantly reduced by N25% of stover removal on a RSL and CSL. Plant available water reserves and earthworm population were significantly reduced by 50% of stover removal at all soils. Increases in soil compaction due to stover removal were moderate. Stover removal impacts on SOC, crop yield, and water infiltration for HCL were not significant. Results from this study following 2 1/2 yr of stover management suggest that only a small fraction (\u226425%) of the total corn stover produced can be removed for biofuel feedstocks from sloping and erosion-prone soils.", "keywords": ["2.

An 11-yr-old field experiment on a sandy loam soil in Denmark was used to compare several crop rotations with respect to a range of physical, chemical and biological characteristics related to carbon (C) and nitrogen (N) flows. Four organic rotations and an inorganic fertilizer-based system were selected to evaluate effects of fertilizer type, catch crops, of grass-clover used as green manure, and of animal manure application. Soil was sampled from winter wheat and spring barley plots on 19 September 2007, 14 April 2008 and 22 September 2008, i.e. before, during, and after the growth season. The soils were analyzed for multiple attributes: total soil organic carbon (SOC), total N, microbial biomass N (MBN), potentially mineralizable N (PMN), and levels of potential ammonium oxidation (PAO) and denitrifying enzyme activity (DEA). In situ measurements of soil heterotrophic carbon dioxide (CO2) respiration and nitrous oxide emissions were conducted in plots with winter wheat. In April 2008, prior to field operations, intact soil cores were collected at two depths (0\u20135 and 5\u201310 cm) in plots under winter wheat. Water retention characteristics of each core were determined and used to calculate relative gas diffusivity (DP/Do). Finally, crop growth was monitored and grain yields measured at harvest maturity. The different management strategies between 1997 and 2007 led to soil carbon inputs that were on average 18\u201368% and 32\u201391% higher in the organic than inorganic fertilizer-based rotations for the sampled winter wheat and spring barley crops, respectively. Nevertheless, SOC levels in 2008 were similar across systems. The cumulative soil respiration for the period February to August 2008 ranged between 2 and 3 t CO2\u2013C ha\u22121 and was correlated (r = 0.95) with average C inputs. In the organic cropping systems, pig slurry application and inclusion of catch crops generally increased soil respiration, PMN and PAO. At field capacity, relative gas diffusivity at 0\u20135 cm depth was >50% higher in the organic than the inorganic fertilizer-based system (P < 0.05). Crop yields in 2008 were generally lower in the low-input organic rotations than in the high-input inorganic fertilizer-based system; only spring barley in rotations with pig slurry application and incorporation of a catch crop prior to sowing obtained grain yields similar to levels achieved in the system where inorganic fertilizer was applied. These results suggest that within organic cropping systems, both microbial activity and crop yields could be enhanced through inclusion of catch crops. However, the timing of catch crop incorporation is critical.", "keywords": ["2. Zero hunger", "microbial biomass", "Nutrient turnover", "inorganic fertilizer", "15.

When the target variables are numeric, the task at hand is called multi-target regression (MTR). An example task of this type is the assessment of quality of agricultural waters in Ireland according to three indicators: biological water quality, nitrogen concentration and phosphorus concentration. Multi-target regression models are typically learnt from labeled training examples, where the values of both the dependent variables (labels) and the independent variables are provided, in a setting known as supervised learning. Many different approaches to supervised multi-target regression have been developed, among which predictive clustering trees and ensembles thereof stand out due to their effectiveness and efficiency. Recently, these approaches have been extended to exploit not only labeled examples, but also unlabeled examples, where only the values of the independent variables are provided, a setting known as semi-supervised learning. In practice, training data can also contain partially labeled examples, where the values of some of the dependent variables are provided and others are missing (in addition to fully labeled examples where all target values are provided and completely unlabeled examples where no target values are provided). For the task of water quality assessment in Ireland, we encounter this kind of partially labeled data. Existing supervised and semi-supervised MTR approaches typically ignore partially labeled data. In this paper, we propose the use of semi-supervised predictive clustering trees for MTR that can handle partially labeled examples. We apply these to the task of assessment of water quality in Ireland, showing that better performance can be achieved if partially labeled examples are exploited, rather than discarded. We build both local models (collections of single-target models predicting each target separately) and global models (multi-target models simultaneously predicting all targets), showing that global models are both smaller and easier to interpret, and also overfit less (and have better performance) as compared to local models.", "keywords": ["0202 electrical engineering", " electronic engineering", " information engineering", "0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "02 engineering and technology", "14.

Since 2007, a middle- to long-term experiment was established in Heyang County, Shaanxi, a region typical of the Loess Plateau, to evaluate the impact of no-tillage (NT), subsoiling tillage (ST) and conventional tillage (CT) on crop yield, water use, and soil water dynamics for winter wheat (Triticum aestivum L.) continuous cropping (WWC), spring maize (Zea mays L.) continuous cropping (SMC), and spring maize-winter wheat rotation cropping (MWR) systems. The highest four-year average wheat yield amounting to 5958\u00a0kg\u00a0ha\u22121 was attained in MWR-ST, while the highest maize yield advantage averaging 772\u00a0kg\u00a0ha\u22121 was obtained in SMC-NT.

At key growth stages, the higher soil water content (SWC) in the 0\u2013200\u00a0cm soil profile was maintained in the conservation tillage and MWR system for wheat but in the conservation tillage and SMC system for maize. The longer-duration fallows did not produce a better effect on SWS at the sowing stage, while the reduction of soil disturbance enhanced SWS compared with CT.

As microbial communities have a high potential to adapt to changing conditions, they are expected to be resilient towards this kind of short-term perturbations and return to their pre-perturbed state quickly. Here, we conducted a lab incubation experiment to evaluate the resilience of soil microbial communities to single-pulse perturbations.

We incubated temperate forest soil at constant temperature (20 \u00b0C) and water content, and exposed it to strong single-pulse perturbations, which nonetheless mimic common pulse-events in temperate soils (glucose addition at 4 mg g\u22121 soil, or freeze-thawing overnight at \u221220 \u00b0C). We subsequently measured microbial community composition and microbial storage compounds via phospho- and neutral lipid fatty acid (PLFA and NLFA) profiling, as well as C/N stoichiometry of microbial biomass and dissolved organic carbon and nitrogen in the soil solution shortly after (0.4, 1, 4, and 6 days) and after longer time periods (84 and 160 days) following the perturbations.

Transferring the soils from their natural environment to the laboratory and incubating them under controlled conditions led to a continuous change of microbial community structure over time, along with an increase in microbial biomass and dissolved N in both perturbed and control soils over the time of the experiment. Against the background of this \u2018press-disturbance\u2019, caused by the permanently changed conditions, we see immediate and long-lasting effects of the single pulse events on microbial community composition, C storage and C/N stoichiometry. Both perturbations significantly influenced the microbial community structure (based on PLFA profiles), microbial biomass N and dissolved N up to 160 days, as well as fungal and bacterial biomass and storage (based on absolute PLFA and NLFA concentrations) up to 84 days. Both perturbations increased microbial N (+59.6 \u00b5g g\u22121 dw) and decreased dissolved N (\u221240.3 \u00b5g g\u22121 dw) after 160 days, and significantly altered C/N ratios in microbial and dissolved pools (particularly in the first 6 days of the experiment).

Our results demonstrate that single-pulse perturbations can have long-term legacies in soil microbial ecosystems. In our experiment they led to alternative system states which differed from the unperturbed control in multiple parameters even after 160 days. This indicates that soil microbial communities exhibit a low resistance and resilience towards single-pulse perturbations, and may easily be pushed on alternative trajectories by short but strong environmental pulses.", "keywords": ["0301 basic medicine", "2.

Increasing atmospheric CO2 concentration has led to concerns about potential effects on production agriculture as well as agriculture's role in sequestering C. In the fall of 1997, a study was initiated to compare the response of two crop management systems (conventional and conservation) to elevated CO2. The study used a split\uffe2\uff80\uff90plot design replicated three times with two management systems as main plots and two CO2 levels (ambient=375\uffe2\uff80\uff83\uffce\uffbcL\uffe2\uff80\uff83L\uffe2\uff88\uff921 and elevated CO2=683\uffe2\uff80\uff83\uffce\uffbcL\uffe2\uff80\uff83L\uffe2\uff88\uff921) as split\uffe2\uff80\uff90plots using open\uffe2\uff80\uff90top chambers on a Decatur silt loam (clayey, kaolinitic, thermic Rhodic Paleudults). The conventional system was a grain sorghum (Sorghum bicolor (L.) Moench.) and soybean (Glycine max (L.) Merr.) rotation with winter fallow and spring tillage practices. In the conservation system, sorghum and soybean were rotated and three cover crops were used (crimson clover (Trifolium incarnatum L.), sunn hemp (Crotalaria juncea L.), and wheat (Triticum aestivum L.)) under no\uffe2\uff80\uff90tillage practices. The effect of management on soil C and biomass responses over two cropping cycles (4 years) were evaluated. In the conservation system, cover crop residue (clover, sunn hemp, and wheat) was increased by elevated CO2, but CO2 effects on weed residue were variable in the conventional system. Elevated CO2 had a greater effect on increasing soybean residue as compared with sorghum, and grain yield increases were greater for soybean followed by wheat and sorghum. Differences in sorghum and soybean residue production within the different management systems were small and variable. Cumulative residue inputs were increased by elevated CO2 and conservation management. Greater inputs resulted in a substantial increase in soil C concentration at the 0\uffe2\uff80\uff935\uffe2\uff80\uff83cm depth increment in the conservation system under CO2\uffe2\uff80\uff90enriched conditions. Smaller shifts in soil C were noted at greater depths (5\uffe2\uff80\uff9310 and 15\uffe2\uff80\uff9330\uffe2\uff80\uff83cm) because of management or CO2 level. Results suggest that with conservation management in an elevated CO2 environment, greater residue amounts could increase soil C storage as well as increase ground cover.

However, limited research has been done to determine how this will influence C and N dynamics and soil functioning. The aim of this work was to investigate the effects of different bioenergy by-products on C and N mineralisation, nutrient availability and microbial content and activity of amended soil and compare them to other more commonly used organic amendments. Two agricultural soils were amended (0.5% w/w) with four different bioenergy by-products (anaerobic digestate, rapeseed meal, bioethanol residue, biochar) and three other commonly used organic amendments (sewage sludge and two composts) and incubated at 20\u00a0\u00b0C in the laboratory for 30 days. During incubation, soil CO2 and N2O evolution were measured every 4\u00a0h by an automatic chromatographic system. After 2, 7 and 30 days of incubation, soil samples were analysed for K2SO4\u2013extractable C, N, NO3\u2212, NH4+ and P, microbial biomass C and three enzymatic activities (\u03b2-glucosidase, alkaline phosphatase and leucine aminopeptidase). Soil amendment led to a general increase in soil respiration, available N and P and microbial content and activity, but with remarkably different dynamics and values. Particularly, rapeseed meal and the bioethanol by-product led to N2O emissions and the greatest increases in soil respiration, N availability and enzymatic activity compared with the other amendments. The exception was represented by biochar that did not cause any significant variation with respect to the control, but promoted C accumulation. According to their impact on soil biochemical properties, the materials can be ranked as follows: rapeseed meal, bioethanol residue\u00a0>\u00a0anaerobic digestate, sewage sludge\u00a0>\u00a0composts\u00a0>\u00a0biochar. For each measured parameter, soil properties did not affect the response pattern found for the different treatments, but modified the magnitude of the response. In particular, soil respiration and enzymatic activity were higher in the slightly acidic soil, while greater values of available P were found in the alkaline soil. This study clearly indicates that the impact on GHG emissions and soil functioning of bioenergy by-products needs to be taken into account for a correct life cycle assessment of the bioenergy chain. Moreover, when properly managed, they may represent an effective alternative to usual amendments to improve the quality and nutrient balance of amended soils.", "keywords": ["2.

Data on soil-profile distribution of C and related soil properties are, however, limited, particularly for semiarid regions. We assessed soil C pool and soil structural properties such as aggregate stability and strength to 1\u00a0m soil depth across three long-term (\u226521\u00a0year) NT and conventional till (CT) experiments along a precipitation gradient in the central Great Plains of the USA. Tillage systems were in continuous winter wheat (Triticum aestivum L.) on a loam at Hutchinson and winter wheat\u2013sorghum [Sorghum bicolor (L.) Moench]-fallow on silt loams at Hays and Tribune, Kansas. Mean annual precipitation was 889\u00a0mm for Hutchinson, 580\u00a0mm for Hays, and 440\u00a0mm for Tribune. Changes in profile distribution of soil properties were affected by differences in precipitations input among the three sites. At Hutchinson, NT had 1.8 times greater SOC pool than CT in the 0\u20132.5-cm depth, but CT had 1.5 times greater SOC pool in the 5\u201320-cm. At Hays, NT had 1.4 times greater SOC pool than CT in the 0\u20132.5-cm depth. Differences in summed SOC pool for the whole soil profile (0\u20131\u00a0m depth) between NT and CT were not significant at any site. The summed SOC pool with depth between NT and CT were only significant above the 5\u00a0cm depth at Hutchinson and 2.5\u00a0cm depth at Hays. At Hutchinson, NT stored 3.4\u00a0Mg\u00a0ha\u22121 more SOC than CT above 5\u00a0cm depth. At Hays, NT stored 1.35\u00a0Mg\u00a0ha\u22121 more SOC than CT above 2.5\u00a0cm depth. Moreover, NT management increased mean weight diameter of aggregates (MWDA) by 3 to 4 times for the 0\u20135-cm depth at Hutchinson and by 1.8 times for the 0\u20132.5-cm depth at Hays. It also reduced air-dry aggregate tensile strength (TS) for the 0\u20135-cm depth at Hutchinson and Hays and for the 0\u20132.5-cm depth at Tribune. The TS (r\u00a0=\u00a0\u22120.73) and MWDA (r\u00a0=\u00a00.81) near the soil surface were more strongly correlated with SOC concentration at Hutchinson than at Hays and Tribune attributed to differences in precipitation input. Results suggested NT impacts on increasing SOC pool and improving soil structural properties decreased with a decrease in precipitation input. Changes in soil properties were larger at Hutchinson (880\u00a0mm of precipitation) than at Hays and Tribune (\u2264580\u00a0mm). While NT management did not increase SOC pool over CT for the whole soil profile, the greater near-surface accumulation of SOC in NT than in CT was critical to the improvement in soil structural properties.

To gain insight into microbial function following increased atmospheric CO2 concentration, we investigated the influence of 9 years of enriched CO2 (600 \uffce\uffbcl litre\uffe2\uff88\uff921) on the function and structural diversity of soil microorganisms in a grassland ecosystem under free air carbon dioxide enrichment (FACE), as affected by plant species (Trifolium repens L. and Lolium perenne L. in monocultures and mixed culture) and nitrogen (N) supply. We measured biomass and activities of enzymes covering cycles of the most important elements (C, N and P). The microbial community was profiled by molecular techniques of phospholipid fatty acid (PLFA) and denaturing gradient gel electrophoresis (DGGE) analysis. The enrichment in CO2 increased soil microbial biomass (+48.1%) as well as activities of invertase (+36.2%), xylanase (+22.9%), urease (+23.8%), protease (+40.2%) and alkaline phosphomonoesterase (+54.1%) in spring 2002. In autumn, the stimulation of microbial biomass was 25% less and that of enzymes 3\uffe2\uff80\uff9312% less than in spring. Strong correlations between activities of invertase, protease, urease and alkaline phosphomonoesterase and microbial biomass were found. The stimulation of microbial activity in the enriched atmosphere was probably caused by changes in the quantity and kind of root litter and rhizodeposition. The response of soil microorganisms to enriched CO2 was most pronounced under Trifolium monoculture and under greater N supply. The PLFA analysis revealed that total PLFA contents were greater by 24.7% on average, whereby the proportion of bioindicators representative of Gram\uffe2\uff80\uff90negative bacteria increased significantly in the enriched CO2 under less N\uffe2\uff80\uff90fertilized Lolium culture. Discriminant analysis showed marked differences between the PLFA profiles of the three plant communities. Shannon diversity indices calculated from DGGE patterns were greater (+12.5%) in the enriched CO2, indicating increased soil bacterial diversity. We conclude that greater microbial biomass and enzyme activity buffer the potential increase in C sequestration occurring from greater C addition in enriched CO2 due to greater mineralization of soil organic matter.

A soil-to-food analysis", "description": "Despite the social concern about the generalization of antibiotic resistance hotspots worldwide, very little is known about the contribution of different potential sources to the global risk. Here we present a quantitative analysis of the distribution of Antibiotic Resistance Genes (ARGs) in soil, rhizospheric soil, roots, leaves and beans in tomato, lettuce and broad beans crops (165 samples in total), grown in nine commercial plots distributed in four geographical zones in the vicinity of Barcelona (North East Spain). We also analyzed five soil samples from a nearby forest, with no record of agricultural activities. DNA samples were analyzed for their content in the ARGs sul1, tetM, qnrS1, blaCTX-M-32, blaOXA-58, mecA, and blaTEM, plus the integron intI1, using qPCR methods. In addition, soil microbiomes from the different plots were analyzed by amplicon-targeted 16S rRNA gene sequencing. Our data show a decreasing gradient of ARG loads from soil to fruits and beans, the latter showing only from 0.1 to 0.01% of the abundance values in soil. The type of crop was the main determinant for both ARG distribution and microbiome composition among the different plots, with minor contributions of geographic location and irrigation water source. We propose that soil amendment and/or fertilization, more than irrigation water, are the main drivers of ARG loads on the edible parts of the crop, and that they should therefore be specifically controlled.", "keywords": ["0301 basic medicine", "2.
