Conversion of arable land (maize) to pasture will affect the soil organic matter (SOM) content. Changes in the SOM content were studied using a size- and density-fractionation method and C-13 analysis. Twenty-six years of maize cropping had resulted in a depletion of carbon stored in the macro-organic fractions (>150 mu m) and an increase in the 250 mu m), light (b.d. 150 mu m) and light (b.d. 150 mu m; b.d. >1.13 g cm(-3)) in the 0- to 20-cm layer was still 40-50% lower than in the continuous pasture plots. Average half-life times calculated from C-13 analyses ranged from 7 years in the light fractions to 56 years in heavy fractions. Fractionation results and C-13 data indicated that mechanical disturbance (plowing) during maize cropping had resulted in vertical displacement of dispersed soil carbon from the 0- to 20-cm layer down to 60-80 cm. Conversion of arable land to pasture, therefore, not only causes a regeneration of the soil carbon content, it also reduces the risk of contaminant transport by dispersed soil carbon.

Because of the importance of fine roots to the belowground C cycle, we monitored fine-root biomass and associated C fluxes in regenerating stands of trembling aspen, and mixed stands of trembling aspen and paper birch at FACTS-II, the Aspen FACE project in Rhinelander, Wisconsin. Free-air CO2 enrichment (FACE) was used to elevate concentrations of CO2 (average enrichment concentration 535\u00a0\u00b5l l-1) and O3 (53\u00a0nl l-1) in developing forest stands in 1998 and 1999. Soil respiration, soil pCO2, and dissolved organic carbon in soil solution (DOC) were monitored biweekly. Soil respiration was measured with a portable infrared gas analyzer. Soil pCO2 and DOC samples were collected from soil gas wells and tension lysimeters, respectively, at depths of 15, 30, and 125\u00a0cm. Fine-root biomass averaged 263\u00a0g m-2 in control plots and increased 96% under elevated CO2. The increased root biomass was accompanied by a 39% increase in soil respiration and a 27% increase in soil pCO2. Both soil respiration and pCO2 exhibited a strong seasonal signal, which was positively correlated with soil temperature. DOC concentrations in soil solution averaged ~12\u00a0mg l-1 in surface horizons, declined with depth, and were little affected by the treatments. A simplified belowground C budget for the site indicated that native soil organic matter still dominated the system, and that soil respiration was by far the largest flux. Ozone decreased the above responses to elevated CO2, but effects were rarely statistically significant. We conclude that regenerating stands of northern hardwoods have the potential for substantially greater C input to soil due to greater fine-root production under elevated CO2. Greater fine-root biomass will be accompanied by greater soil C efflux as soil respiration, but leaching losses of C will probably be unaffected.", "keywords": ["0106 biological sciences", "Ecology and Evolutionary Biology", "Aspen-FACE-project", "root-", "USA-", "pollutants-", "Environmental-Sciences)", "tropospheric-ozone", "forest-productivity", "01 natural sciences", "biomass-", "northern-forests", "124-38-9: CARBON DIOXIDE", "soil-carbon-flux", "terrestrial-ecosystems", "populus-tremuloides", "Cellular and Developmental Biology", "soil-carbon", "7440-44-0: CARBON", "carbon-", "fine-root", "Bioenergetics- (Biochemistry-and-Molecular-Biophysics)", "Natural Resources and Environment", "04 agricultural and veterinary sciences", "GLOBAL-ECOLOGY", "North-America", "Nearctic-region)", "Rhinelander- (Wisconsin-", "carbon-sequestration", "atmosphere-", "biomass-production", "dissolved-organic-carbon [DOC-]", "Science", "respiration-", "carbon-dioxide-enrichment", "forest-plantations", "carbon-dioxide", "carbon-storage", "fine-root-biomass", "belowground-biomass", "United-States-Wisconsin-Rhinelander", "carbon-cycle", "Health Sciences", "ozone-", "soil-respiration", "air-pollution", "global-change", "atmospheric-carbon-dioxide", "biomass", "Molecular", "15.

Tropical forests play an important role in the global carbon (C) cycle, yet the effects of N deposition on C cycling in these ecosystems are poorly understood. We used a field N-fertilization experiment in lower and upper elevation tropical rain forests in Puerto Rico to explore the responses of above- and belowground C pools to N addition. As expected, tree stem growth and litterfall productivity did not respond to N fertilization in either of these N-rich forests, indicating a lack of N limitation to net primary productivity (NPP). In contrast, soil C concentrations increased significantly with N fertilization in both forests, leading to larger C stocks in fertilized plots. However, different soil C pools responded to N fertilization differently. Labile (low density) soil C fractions and live fine roots declined with fertilization, while mineral-associated soil C increased in both forests. Decreased soil CO2 fluxes in fertilized plots were correlated with smaller labile soil C pools in the lower elevation forest (R2\u00a0=\u00a00.65, p\u00a0<\u00a00.05), and with lower live fine root biomass in the upper elevation forest (R2\u00a0=\u00a00.90, p\u00a0<\u00a00.05). Our results indicate that soil C storage is sensitive to N deposition in tropical forests, even where plant productivity is not N-limited.

Exotic earthworm invasion of northern forest soils in North America can affect soil C pools, and we examined their effects on these mechanisms by adding 13C labeled leaf litter to adjacent northern hardwood forests with and without earthworms. Two types of labeled litter were produced, one with the 13C more concentrated in structural (S) components and the other in non-structural (NS) components, to evaluate the role of biochemical differences in soil C stabilization. Earthworm invasions have reduced soil C storage in the upper 20\u00a0cm of the soil profile by 37\u00a0%, mostly by eliminating surface organic horizons. Despite rapid mixing of litter into mineral soil and its incorporation into aggregates, mineral soil C has not increased in the presence of earthworms. Incorporation of litter C into soil and microbial biomass was not affected by biochemical differences between S versus NS labeled litter although NS litter C was assimilated more readily into earthworm biomass and S litter C into fungal hyphae. Apparently, the net effect of earthworm mixing of litter and forest floor C into mineral soil, plus stabilization of that C in aggregates, is counterbalanced by earthworm bioturbation and possible priming effects.

Previous studies in the region have shown the potential of AFS to store organic carbon in the soil. In the present work, we carried out further studies to assess the main factors affecting SOC stocks in AFS. In 2014, we performed a soil sampling on 137 AFS farmers'plots to assess SOC stocks in different AFS. In 2018, a second sampling was carried out to calculate SOC storage rates using the diachronic approach on 30 most representative AFS. The results revealed that the factors 'age of the system' and 'type of organic inputs' significantly affected SOC stocks in AFS. SOC stocks increased significantly over time in AFS plots, benefiting from regular organic inputs such as manure and/or compost. In contrast, SOC stocks remained unchanged over time in AFS plots where no organic fertilization was used. Our study showed a substantial SOC storage up to 47 parts per thousand year(-1), mainly explained by regular additions of organic inputs to maintain soil fertility and crop production.

The aim of this study was to assess the future soil erosion risks and evaluate the potential conservation measures in the Rib watershed, northwestern highland Ethiopia. We used the HadGEM2-ES model with a moderate greenhouse gas (GHG) concentration scenario (RCP4.5) to project the future climate. The future land-use patterns were predicted using the CA-Markov model. We integrated the RUSLE model with GIS to estimate the spatial distribution of soil loss and identify erosion risk areas. We found that the Rib watershed is highly vulnerable to future climate and land-use changes, leading to a high soil erosion risk. Despite slight growth of forest cover during the study period, the total soil loss for the watershed was estimated to be 7.93\u2009\u00d7\u2009106\u00a0t\u00a0year\u22121 in 2017 and was predicted to increase to 9.75\u2009\u00d7\u2009106\u00a0t\u00a0year\u22121 in 2050, an increase of about 23%. The increase in forest cover was due to the expansion of the area of eucalyptus plantations which are more prone to erosion. Moreover, field survey showed that the residual native forests are sparsely vegetated and mostly used for cattle grazing, increasing the erosion risk even more. In contrast, the combined use of afforestation with native trees and physical soil conservation measures in the upper areas of the catchment could decrease soil loss by 62%. Our results stress the importance of combining soil conservation measures, including converting eucalyptus plantations to native forests, to mitigate the effects of future climate change and increased agricultural production on soil erosion.", "keywords": ["2.

Soils were incubated in microcosms during 64 days at optimum temperature and humidity. Bacterial and fungal diversity were evaluated by metagenomic 454-pyrosequencing of 16S and 18SrRNA genes, respectively.

One pool of carbon considered particularly stable across climate zones and soil types is formed when dissolved organic carbon sorbs to minerals. We quantified, for the first time, the potential of mineral soils to sorb additional dissolved organic carbon (DOC) for six soil orders. We compiled 402 laboratory sorption experiments to estimate the additional DOC sorption potential, that is the potential of excess DOC sorption in addition to the existing background level already sorbed in each soil sample. We estimated this potential using gridded climate and soil geochemical variables within a machine learning model. We find that mid- and low-latitude soils and subsoils have a greater capacity to store DOC by sorption compared to high-latitude soils and topsoils. The global additional DOC sorption potential for six soil orders is estimated to be 107 $$ pm$$ \uffc2\uffb1 13 Pg C to 1\uffc2\uffa0m depth.

Key soil parameters and plant nutrient uptake were investigated alongside stable 15\u2009N isotope methodologies to elucidate the causal mechanisms for enhanced biological N2 fixation and crop productivity. Biological N2 fixation was associated with plant Mo uptake, which was driven by reductions in soil acidity following lime and papermill (PM) biochar amendment.

The sites that have undergone revegetation (LEGS and BS) had higher densities of bacteria, fungi, phosphate solubilizers and ammonium oxidizers than the sites without vegetation. Principal component analysis showed that the LEGS site grouped with PRNH, indicating that the use of leguminous species associated with an uncontaminated soil cover layer contributed to the improvement of the biological attributes.

Conservation tillage, including no-till (NT), has been proposed as an alternative to conventional plow till (PT) to mitigate soil erosion, but past studies have reported mixed results on the effect of conservation tillage on pesticide loss. To explore the underlying factors of these differences, a meta-analysis was conducted using published data on pesticide concentration and load in agricultural runoff from NT and PT fields. Peer-reviewed articles (1985-2016) were compiled to build a database for analysis. Contrary to expectations, results showed greater concentration of atrazine, cyanazine, dicamba, and simazine in runoff from NT than PT fields. Further, we observed greater load of dicamba and metribuzin, but reduced load of alachlor from NT fields. Overall, the concentration and the load of pesticides were greater in runoff from NT fields, especially pesticides with high solubility and low affinity for solids. Thus, NT farming affects soil properties that control pesticide retention and interactions with soils, and ultimately their mobility in the environment.

However, this benefit is lost quickly during the cropping phase. The objective of this study was to evaluate SOC dynamics of an improved fallow-maize rotation under no-tillage (NT) and conventional tillage (CT) from time of fallow termination, through the next two cropping seasons. The treatments studied were improved fallows of Acacia angustissima (A. angustissima) and Sesbania sesban (S. sesban), natural fallow and continuous maize. Our hypothesis is that fallowing maintained higher SOC and lower soil bulk densities through the cropping phase when compared with continuous maize system and that NT maintained higher SOC when compared with CT. Soil organic carbon was significantly greater under fallows than under continuous maize from fallow termination to the end of the second cropping season. Soil organic carbon for the 0\u20135 cm depths was 11.0, 10.0, 9.4 and 6.6 g kg\u22121 for A. angustissima, S. sesban, natural fallow and continuous maize, respectively at fallow termination. After two cropping seasons SOC for the same depth was 8.0, 7.0, 6.1, 5.9 g kg\u22121 under CT and 9.1, 9.0, 8.0, 6.0 g kg\u22121 under NT for A. angustissima, S. sesban, natural fallow and continuous maize, respectively.

Soil bulk densities were lower under fallows when compared with continuous maize during the period of study. We concluded that fallows maintained greater SOC and NT sequestered more SOC than CT.

This study was conducted in the highlands of western Kenya, a region with high potential for agroforestry, with the objectives of assessing current biodiversity and aboveground C stocks in perennial vegetation growing on farmland, and estimating C sequestration potential in aboveground C pools. Allometric models were developed to estimate aboveground biomass of trees and hedgerows, and an inventory of perennial vegetation was conducted in 35 farms in Vihiga and Siaya districts. Values of the Shannon index ( H ), used to evaluate biodiversity, ranged from 0.01 in woodlots through 0.4\u20130.6 in food crop plots, to 1.3\u20131.6 in homegardens. Eucalyptus saligna was the most frequent tree species found as individual trees (20%), in windrows (47%), and in woodlots (99%) in Vihiga and the most frequent in woodlots (96%) in Siaya. Trees represented the most important C pool in aboveground biomass of perennial plants growing on-farm, contributing to 81 and 55% of total aboveground farm C in Vihiga and Siaya, respectively, followed by hedgerows (13 and 39%, respectively) and permanent crop stands (5 and 6%, respectively). Most of the tree C was located in woodlots in Vihiga (61%) and in individual trees growing in or around food crop plots in Siaya (57%). The homegardens represented the second C pool in importance, with 25 and 33% of C stocks in Vihiga and Siaya, respectively. Considering the mean total aboveground C stocks observed, and taking the average farm sizes of Vihiga (0.6\u00a0ha) and Siaya (1.4\u00a0ha), an average farm would store 6.5\u00a0\u00b1\u00a00.1\u00a0Mg\u00a0C\u00a0farm \u22121 in Vihiga and 12.4\u00a0\u00b1\u00a00.1\u00a0Mg\u00a0C\u00a0farm \u22121 in Siaya. At both sites, the C sequestration potential in perennial aboveground biomass was estimated at ca. 16\u00a0Mg\u00a0C\u00a0ha \u22121 . With the current market price for carbon, the implementation of Clean Development Mechanism Afforestation/Reforestation (CDM A/R) projects seems unfeasible, due to the large number of small farms (between 140 and 300) necessary to achieve a critical land area able to compensate the concomitant minimum transaction costs. Higher financial compensation for C sequestration projects that encourage biodiversity would allow clearer win\u2013win scenarios for smallholder farmers. Thus, a better valuation of ecosystem services should encourage C sequestration together with on-farm biodiversity when promoting CDM A/R projects.", "keywords": ["550", "petite exploitation agricole", "DIVERSITE SPECIFIQUE", "EXPLOITATION AGRICOLE", "01 natural sciences", "agroforestry", "eucalyptus saligna", "biodiversit\u00e9", "sistemas de explotaci\u00f3n", "STOCKAGE", "allocation", "soil fertility management", "agroforesterie", "2.

A series of field experiments were carried out during October 2004 and September 2007 in a lysimeter field to reveal the temporal changes of N leaching losses below 2-m depth from this land system as well as the effects of N fertilizer application rates on N leaching. Four N rates (0, 180, 260, and 360 kg N ha(-1) as urea) were applied in the study area. Seasonal leachate volumes were 87 and 72 mm in the first and second maize season, respectively, and 13 and 4 mm during the winter wheat and maize season in the third rotational year, respectively. The average seasonal flow-weighted NO(3)-N concentrations in leachate for the four N fertilizer application rates ranged from 8.1 to 103.7 mg N l(-1), and seasonal flow-weighted dissolved organic nitrogen (DON) concentrations in leachate varied from 0.8 to 6.0 mg N l(-1). Total amounts of NO(3)-N leaching lost throughout the 3 years were in the range of 14.6 to 177.8 kg ha(-1) for the four N application rates, corresponding to N leaching losses in the range of 4.0-7.6% of the fertilizers applied. DON losses throughout the 3 years were 1.4, 2.1, 3.6, and 6.3 kg N ha(-1) for the four corresponding fertilization rates. The application rate of 180 kg N ha(-1) was recommended based on the balance between reducing N leaching and maintaining crop yields.

During Vegetative Growth?", "description": "The objective of this work was to determine if the impact of nitrogen (N) on the release of organic carbon (C) into the soil by roots (rhizodeposition) correlated with the effect of this nutrient on some variables of plant growth. Lolium multiflorum Lam. was grown at two levels of N supply, either in sterile sand percolated with nutrient solution or in non-sterile soil. The axenic sand systems allowed continuous quantification of rhizodeposition and accurate analysis of root morphology whilst the soil microcosms allowed the study of 14C labelled C flows in physico-chemical and biological conditions relevant to natural soils. In the axenic sand cultures, enhanced N supply strongly increased the plant biomass, the plant N content and the shoot to root ratio. N supply altered the root morphology by increasing the root surface area and the density of apices, both being significantly positively correlated with the rate of organic C release by plant roots before sampling. This observation is consistent with the production of mucilage by root tips and with mechanisms of root exudation reported previously in the literature, i.e. the passive diffusion of roots solutes along the root with increased rate behind the root apex. We proposed a model of root net exudation, based on the number of root apices and on root soluble C that explained 60% of the variability in the rate of C release from roots at harvest. The effects of N on plant growth were less marked in soil, probably related to the relatively high supply of N from non-fertiliser soil-sources. N fertilization increased the shoot N concentration of the plants and the shoot to root ratio. Increased N supply decreased the partitioning of 14C to roots. In parallel, N fertilisation increased the root soluble 14C and the 14C recovered in the soil per unit of root biomass, suggesting a stimulation of root exudation by N supply. However, due to the high concentration of N in our unfertilised plants, this stimulation was assumed to be very weak because no significant effect of N was observed on the microbial C and on the bacterial abundance in the rhizosphere. Considering the difficulties in evaluating rhizodeposition in non sterile soil, it is suggested that the root soluble C, the root surface area and the root apex density are additional relevant variables that should be useful to measure along with the variables that are commonly determined when investigating how plant functioning impacts on the release of C by roots (i.e soil C, C of the microbial biomass, rhizosphere respiration).", "keywords": ["580", "2.

Field trials were conducted in 2002 and 2003\u00a0at Ikenne southwestern Nigeria to investigate the effect of weed pressures and drought stress on 2 maize (Zea mays L.) hybrids (9134-14, 9803-9) and 2 open-pollinated varieties (STREVIWD, IYFDCO1). Irrigation was withdrawn 4 weeks after planting (about four weeks to mid-flowering) in the drought stress while the adjacent watered treatment had irrigation throughout the growing period. The weed pressures were the completely weeded plots (hand weeding every week) and weedy plots (weeded once, 2 weeks after planting). The experiment was a split plot in a randomized complete block design with four replicates. Drought stress reduced the stover weight and grain yield of the maize cultivars by 6% and 34% respectively. Weed-free plots had maize with higher agronomic traits than unweeded treatments. Hybrid 9803-9 was more susceptible to drought and weed stress as indicated in the stover weight and grain yield. STREVIWD an open-pollinated variety (OPV) and Hybrid 9134-14 had superior performances in terms of grain yield and shorter anthesis silking interval.

The objective of this work was to understand the dynamics of soil carbon in intensively managed Eucalyptus plantations after the afforestation of a native savannah. The isotopic composition (\u03b4) of soil carbon (C) and soil CO2 efflux (F) were measured on a four-age chronosequence of Eucalyptus and on an adjacent savannah. \u03b4 F was used to partition F between a C3 component and a C4 component, the latter corresponding to the decomposition of a labile pool of savannah-derived soil carbon (C SL). The mean residence time of CSL was 4.6\u00a0years. This further allowed us to partition the savannah-derived soil carbon into a labile and a stable (C SS) carbon pool. C SL accounted for 30% of soil carbon in the top soil of the savannah (0\u20135\u00a0cm), and only 12% when the entire 0\u201345\u00a0cm soil layer was considered. The decrease in C SL with time after plantation was more than compensated by an increase in Eucalyptus-derived carbon, and half of the newly incorporated Eucalyptus-derived carbon in the top soil was associated with the clay and fine silt fractions in the 14-year-old. stand.

A 3-year field study (2003, 2004 and 2005) was carried out on a typical Vertisol (southern Spain), to determine the effects of tillage system on root growth in spring wheat (Triticum aestivum L) grown in continuous rotation with faba bean (Vicia faba L), within the framework of the long-term \u201cMalag\u00f3n\u201d experiment started in 1986. Tillage treatments were no-tillage (NT) and conventional tillage (CT), and the experiment was designed as a randomized complete block with three replications. The following parameters were measured: above-ground biomass, grain yield, root length density (RLD), root biomass (RB) and root N content. In the topmost 10 cm of soil, higher values were found under CT than under NT for RLD in the rainiest year (20.2 km m\u22123 vs. 9.6 km m\u22123 respectively) and for RB (512 kg ha\u22121 vs. 261 kg ha\u22121 respectively) in all study years. In deeper layers, no difference was recorded between the two tillage systems. Greater wheat root development in the upper soil layer under CT may reflect the greater soil penetration resistance found in the topmost 10 cm under NT. Root separation using a sieve with a 0.5 mm mesh screen led to a marked underestimation of RLD and RB, with values up to three times higher when using a 0.2 mm mesh screen. Mean wheat root N content in the topmost 30 cm of soil accounted for over 80% of total root N content. The highest grain yield was observed under NT, since this system provided greater water storage in the soil profile in the mostly dry study years.", "keywords": ["2.

However, the global spatial and temporal dynamics of transpiration are highly uncertain, and current estimates rely on either indirect remote sensing or empirical model formulations. Here, we show that T can be estimated reliably at the global scale using observations of plant sun-induced fluorescence (SIF). To do so, we derive T using two different methods from globally-distributed eddy-covariance measurements and compare it with satellite SIF retrievals from GOME-2 and OCO-2. Whereas most research to date has focused on the link between SIF and gross primary production (GPP), we demonstrate that SIF is as highly correlated with T (mean correlation coefficient R of 0.76 across sites for 16-day periods with GOME-2 and 0.75 at the daily scale with OCO-2). SIF shows a greater predictive skill to estimate T than traditional optical vegetation indices and its dynamics are very similar to those of T. Through the use of an advanced radiative transfer model, we also demonstrate a clear empirical link between SIF and T. At 83 FLUXNET sites, remote sensing data and flux-derived GPP and T are used to estimate the relevant parameters of the Soil Canopy Observation of Photosynthesis and Energy fluxes (SCOPE) radiative transfer model and to model SIF. While the relationship between SIF and photosynthesis (GPP) is mostly controlled by leaf biochemical properties and plant structure, the SIF-T relationship appears largely determined by air temperature and intrinsic water use efficiency.

The objective of this study was to assess impacts of long-term (>75\u00a0years) grazing during spring (SPG), summer (SUG), winter (WG) and exclosure (non-grazed control) treatments on soil nutrients, penetration resistance and infiltration tests. A soil sampling campaign was carried out to collect soil to a depth of 60\u00a0cm to analyse bulk density, soil physical and chemical parameters as well as soil compaction and infiltration. Generally, grazing treatments reduced soil organic C (SOC) stocks and C:N ratios, and modified soil properties. There was higher SOC stock (0.128\u00a0Mg\u00a0ha\u22121\u00a0yr\u22121) in the exclosure than in the SPG (0.096\u00a0Mg\u00a0ha\u22121\u00a0yr\u22121), SUG (0.099\u00a0Mg\u00a0ha\u22121\u00a0yr\u22121) and WG (0.105\u00a0Mg\u00a0ha\u22121\u00a0yr\u22121). The C:N ratios exhibited similar pattern to that of C. From the grazing treatments, the WG demonstrated 7 to 10\u00a0% additional SOC stock over the SPG and SUG, respectively.

This work aims at providing insights into the link between DOC cycling during rice cropping and organic C input to the subsoils and export with surface waters, as well as methane (CH4) emissions in a temperate paddy soil as a function of different water management practices. DOC quantity, quality and fluxes, as well as CH4 emissions were evaluated at field-scale over two cropping seasons for three water management systems including continuous flooding, dry seeding with delayed flooding, and intermittent irrigation. DOC cycling in the different water management systems were strongly linked to the reducing soil conditions resulting from field flooding. In contrast to dry seeding or intermittent irrigation, adoption of continuous flooding not only favoured the accumulation of DOC in the topsoil (>10\u201320\u00a0mg C l\u22121), but also enhanced C inputs to the subsoil (33\u201351\u00a0g C m\u22122), and exports with surface waters (18\u201344\u00a0g C m\u22122). Moreover, changes in DOC quality in paddy soils were linked to a positive feedback on the abiotic release of soil-derived DOC, and substrate availability for CH4 production.

In contrast, microbial community structure can be shifted within the first decade and so, the direct effects of tree species can be revealed. The aim of this study was to determine the alteration of soil microbial community composition 10\u00a0years after afforestation by trees with contrasting functional traits. Methods: The study was conducted at the BangorDIVERSE temperate forest experiment. Soil samples were collected under single, two and three species mixtures of alder and birch, beech and oak - early and secondary successional species, respectively, and contiguous agricultural field. Soil was analysed for total carbon (C) and nitrogen (N) contents, and microbial community structure (phospholipid fatty acids (PLFAs) analysis). Results and conclusions: The total PLFAs content (370\u2013640\u00a0nmol\u00a0g\u22121soil) in forest plots increased for 30 to 110\u00a0% compared to the agricultural soil (290\u00a0nmol\u00a0g\u22121soil). In contrast, soil C, N and C/N ratios were altered over 10\u00a0years much less - increased only up to 20\u00a0% or even decreased (for beech forest). Afforestation increased bacterial PLFAs by 20\u2013120\u00a0%, whereas it had stronger impact on the development of fungal communities (increased by 50\u2013200\u00a0%). These effects were proved for all forests, but were more pronounced under the monocultures compared to mixtures. This indicates that species identity has a stronger effect than species diversity. Principal component analysis of PLFAs revealed that under mono and three species mixtures similar microbial communities were formed. In contrast, gram-positive PLFAs and actinomycete PLFAs contributed mainly to differentiation of two species mixtures from other forests. Thus, at the early afforestation stage: i) soil biological properties are altered more than chemical, and ii) tree species identity affects more than species amount on both processes.", "keywords": ["2.

Quantitative PCR was applied to evaluate the abundance of relevant microbial groups. Phosphorus availability and microbial biomass systematically increased in the rhizosphere compared to bulk soil. P-fertilization resulted in higher abundance of targeted bacterial phyla, whole bacterial and fungal communities, and depressed mycorrhizal colonization of durum wheat, but not faba bean. Microbial biomass carbon significantly increased in the rhizosphere only in P-fertilized treatments, pointing to P limitation of microbial communities. Intercropping yielded a significant effect on rhizosphere microbial properties only at High P. Microbial biomass P increased in the rhizosphere of intercropped faba bean only at No P level, and was thus the sole finding supporting the stress-gradient hypothesis.

Thinning of native forests helps to preserve native tree species and is more sustainable than replacing native forest stands with mono-species plantations to produce timber. This study aimed to explore the effects of native forest thinning on soil-plant carbon (C) and nitrogen (N) dynamics in two experimental sites, Esk (5\u00a0years post-thinning) and Herberton (7\u00a0years post-thinning), situated in Queensland, Australia. The two sites had different thinning regimes. The final stocking rates varied between 75 and 200 stems ha\u22121 at Esk and between 250 and 400 stems ha\u22121 at Herberton. The thinned plots were compared to un-thinned plots. Soil samples were collected to measure labile C and N. Leaf samples were collected from C. variegata and C. citriodora in Esk and Herberton respectively. Thinning did not change soil total C, total N, \u03b415N and inorganic N at either Esk or Herberton. However, at Esk, intensive thinning resulted in decreases in water soluble total N (WSTN). Foliar \u03b413C did not vary with respect to thinning whereas foliar \u03b415N values were more enriched in thinned areas than those of un-thinned plots. The stepwise linear regression indicated that both foliar total N and \u03b415N were explained mainly by soil TN and WSTN. Thinning did not change soil C and N most likely due to the retention of thinned materials on site and their incorporation into soil. Foliar \u03b413C was not thinning-dependent due to homeostatic maintenance of the ratio of intercellular to ambient CO2 concentrations during photosynthesis.

Increasing food demand coupled with climate change pose a great challenge to agricultural systems. In this review we summarize recent advances in our knowledge of how plants, together with their associated microbiota, shape rhizosphere processes. We address (molecular) mechanisms operating at the plant\uffe2\uff80\uff93microbe-soil interface and aim to link this knowledge with actual and potential avenues for intensifying agricultural systems, while at the same time reducing irrigation water, fertilizer inputs and pesticide use. Combining in-depth knowledge about above and belowground plant traits will not only significantly advance our mechanistic understanding of involved processes but also allow for more informed decisions regarding agricultural practices and plant breeding. Including belowground plant-soil-microbe interactions in our breeding efforts will help to select crops resilient to abiotic and biotic environmental stresses and ultimately enable us to produce sufficient food in a more sustainable agriculture in the upcoming decades.In the attempt to foster circular economy (CE), cities are increasingly adopting urban living labs (ULLs) as sites of co-production aimed at testing alternative solutions based on the reuse of products, reduction of consumption and recycling of materials. Taking this perspective, our study adopts an exploratory research design to discover the pragmatic implications emerging from a case study. The City of Turin joined proGIreg, a European project that entails the regeneration of former industrial districts by means of nature-based solutions (NBS). Ranging from aquaponics to green roofs, seven NBS have been experimented in Turin, which rely on the use of natural systems to tackle social, economic and environmental challenges efficiently and sustainably. Among them, the most promising is related to the production and test of the \uffe2\uff80\uff98new soil\uffe2\uff80\uff99, a blend obtained by mixing earth materials coming from construction sites with compost, zeolites and mycorrhizae. The case herein presented is interesting to analyse for the multi-stakeholder management setting used, where public institutions, private companies, research institutions, citizens and associations collaborated in the co-creation and testing phase of the NBS. Consequently, the data collected through participant observation and direct interviews allow researchers to describe multi-stakeholders\uffe2\uff80\uff99 dynamics and how they work. Thus, this paper narrates a micro-contextual experience while providing a critique. Results include an analysis of the unique combination of different stakeholders, which strongly impacted on the management and the effectiveness of the entire project. By consequence, the paper offers both theoretical contributions to the relational branch of stakeholder theory and practical evidence in demonstrating the importance of the relational branch of the theory over a more traditional transactional view.

Alternative systems such as conservation agriculture and organic farming could restore better conditions for soil organisms. Improving soil life should in turn improve soil quality and farming sustainability. Here, we have compared for the first time the long-term effects of conservation agriculture, organic farming, and conventional agriculture on major soil organisms such as microbes, nematofauna, and macrofauna. We have also analyzed functional groups. Soils were sampled at the 14-year-old experimental site of La Cage, near Versailles, France. The microbial community was analyzed using molecular biology techniques. Nematofauna and macrofauna were analyzed and classified into functional groups. Our results show that both conservation and organic systems increased the abundance and biomass of all soil organisms, except predaceous nematodes. For example, macrofauna increased from 100 to 2,500 %, nematodes from 100 to 700 %, and microorganisms from 30 to 70 %. Conservation agriculture showed a higher overall improvement than organic farming. Conservation agriculture increased the number of many organisms such as bacteria, fungi, anecic earthworms, and phytophagous and rhizophagous arthropods. Organic farming improved mainly the bacterial pathway of the soil food web and endogeic and anecic earthworms. Overall, our study shows that long-term, no-tillage, and cover crops are better for soil biota than periodic legume green manures, pesticides, and mineral fertilizers.", "keywords": ["570", "biodiversit\u00e9 du sol", "[SDV]Life Sciences [q-bio]", "630", "Soil quality", "n\u00e9matofaune", "microorganisme du sol", "agriculture biologique", "Soil food web", "Land management", "11.

The durability of the commonly used silvered-glass reflectors is typically qualified by means of accelerated aging. Recently, the Spanish standardization committee UNE has published the first specific standard for this topic, which defines a set of accelerated aging tests for CSP reflectors. However, the standard does not contain pass/fail criteria. This paper proposes useful acceptance criteria for the accelerated tests defined by UNE, helping to interpret the obtained degradation results. The criteria have been determined by analyzing the collected accelerated aging data over the past 5 years in the OPAC laboratory, a joint research group of DLR and CIEMAT. Data from six different 4\u202fmm silvered-glass manufacturers is presented, covering nearly the entire market of commercially available silvered-glass mirrors, and going way beyond the recommended testing times of the UNE standard. The data may be used to benchmark initial reflective properties (before aging) and the performance during accelerated durability testing. In addition, recommendations for improvements of the standard are given and an estimate of the acceleration factor of the Copper Accelerate Salt Spray (CASS) test with respect to a highly corrosive outdoor environment is presented.", "keywords": ["reflectance", "solar reflector", "0211 other engineering and technologies", "0202 electrical engineering", " electronic engineering", " information engineering", "durability", "Qualifizierung", "02 engineering and technology", "accelerated aging testing", "7.

The consequences of deforestation and conversion to pasture for soil carbon content and dynamics were examined in two soil types differing mainly by their texture. Two chronosequences were selected, each consisting of an intact forest and three pastures of different ages (4, 8, 15 years and 3, 9, 15 years, respectively). One chronosequence is located in the central part of the Brazilian Amazon basin, where the soils are clayey ferralsols, and the second in the Eastern Brazilian Amazon Basin, where the soils are sandy clayey acrisols. In the upper layer the C content of clayey soils was three times higher than in the sandy soils, but despite the differences in soil texture, the C distribution in the particle-size fractions was quite similar. In the two chronosequences, the conversion to pasture induced a slight increase in C content. Bulk density increases were greater on soils with lower clay contents. The 13 C measurements, which allowed to calculate the distribution of C derived from forest and from pasture, showed that all the particle-size fractions incorporated C derived from pasture and that a significant proportion of the young organic matter is rapidly trapped in the finest fractions.

Local researches are necessary to gain information on buffer performance, with particular emphasis on narrow buffers. The effect of a 6\u00a0m buffer strip (BS) in reducing runoff, suspended solids and nutrients from a field growing maize, winter wheat and soybean was assessed in a field experiment conducted in North-East Italy during 1998\u20132001. The BS was composed of two rows of regularly alternating trees (Platanus hybrida Brot.) and shrubs (Viburnum opulus L.), with grass (Festuca arundinacea L.) in the inter-rows. The BS reduced total runoff by 78% compared to no-BS, in which cumulative runoff depth was 231\u00a0mm over 4 years. With no-BS runoff appeared to be influenced mostly by total rainfall, while with BS maximum rainfall intensity was more important. The filtering effect of the BS reduced total suspended solids (TSS), particularly after the second year, when the median yearly concentrations ranged from 0.28 to 0.99\u00a0mg\u00a0L\u22121 and were smaller than 0.14\u00a0mg\u00a0L\u22121, with no-BS and with BS respectively. The combination of lower concentrations and runoff volumes significantly reduced TSS losses from 6.9 to 0.4\u00a0t\u00a0ha\u22121 over the entire period. A tendency to increased concentrations of all forms of N (total, nitrate and ammonium) while passing through the BS was observed, but total N losses were reduced from 17.3 to 4.5\u00a0kg\u00a0ha\u22121 in terms of mass balance. On the contrary, P concentrations were unmodified (soluble P), or lowered (total P) by the BS, reducing total losses by about 80%. The effect on total P, composed mainly of sediment-bound forms, was related to particulate settling when passing through the BS. A numerical index (Eutrophic Load Index), integrating water quality and runoff volumes, was created to evaluate the eutrophication risk of runoff with or without the BS. It showed that the BS effect was mostly due to a reduction of runoff volumes rather than improving the overall water quality.", "keywords": ["2. Zero hunger", "13. Climate action", "14.

These soils form the basis of agricultural production systems on which significant numbers of people depend upon for livelihoods. The objectives of this study were to investigate soil acidification following the introduction of Stylosanthes in cropping systems of a tropical semi-arid region. Most soils in Northeast Thailand are sandy and acidic (pH 4.0 in CaCl2) with high rate of drainage. Soil acidification was studied over a 6-year period on plots that had been treated either with or without lime additions under different cropping patterns. In the initial first 3 years, a rotation of maize and cowpea was compared to a bare soil treatment where no vegetation was allowed to establish. During the following 3 years, a rotation of maize and Stylosanthes was compared to a continuous Stylosanthes hamata (stylo) treatment. Total soil acidification was calculated from measured pH changes and pH buffer capacity. Acidification due to root system activity was estimated from the above ground biomass production and its ash alkalinity. In the limed systems, soil pH decrease was well correlated with the ash alkalinity of the crop and its removal from the plot. Acidification was highest in the bare soil (6.3 kmol H+ ha(-1) year(-1)), due to leaching of applied N fertilizers. The cowpea-maize rotations did not increase significantly the rate of acid addition (7.6 kmol H+ ha(-1) year(-1)), since the crop residues were returned to the plot. The introduction of stylo in the cropping system resulted in a lower net acidification rate when it was cultivated in rotation with maize (1.3 kmol H+ ha(-1) year(-1)), due to the lower rate of leaching. In contrast, continuous cultivation of stylo triggered accelerated acidification (7.2 kmol H+ ha(-1) year(-1)), as a result of the large quantities of biomass with high ash alkalinity being removed from the plot. In the no-lime system, the pH of the soil profile remained stable at pH 4.0 regardless of the cropping system, even though the acidification rates were quite similar to those in the limed treatments. This would suggest that the soil was strongly buffered at pH 4.0. XRD patterns showed that kaolinite, the main clay mineral, was more disordered and less crystalline in the surface horizons than at depth. It is suggested that the dissolution of kaolinite is responsible for the buffering of soil pH at 4.0. From the dissolution equation of kaolinite, it is expected that the amount of aluminium in the topsoil would increase along with the release silica that would accelerate cementation processes between soil particles resulting in further degradation.

The objectives of this study were to investigate the impacts of conventional tillage (CT), no tillage (NT), and wheat cropping sequences on the depth distribution of dissolved organic C (DOC), soil organic C (SOC), and total N in a central Texas soil after 20 years. Soil was sampled for six depth intervals ranging from 0 to 105 cm. Conventional tillage consisted of disking, chiseling, ridging, and residue incorporation into soil, while residues remained on the soil surface for NT. The depth distribution of DOC was similar to SOC. Tillage impacts on DOC, SOC, and total N were primarily observed in surface soil (0-5 cm) under continuous wheat but also in subsurface soil depth intervals down to 55 cm for more intensive cropping sequences. On average, NT increased SOC, DOC, and total N compared to CT by 28, 18, and 33%, respectively. Soil organic C and total N were highest at 0-5 cm and decreased with depth to 30-55 cm, below which few tillage or cropping sequence effects were observed. The depth distribution of SOC and total N indicated treatment effects below levels of the maximum tillage depth, while intensive cropping increased SOC and total N for NT compared to CT to a greater depth than for monoculture wheat. High intensity cropping sequences, coupled with NT, resulted in the highest soil organic matter levels in subsurface soils, demonstrating the importance of subsurface C and N storage for potential mitigation of greenhouse gases.", "keywords": ["2.
