This work evaluates the release of phosphorus contained in the digestate from the anaerobic digestion of pig manure, through an acidification process. The objective of this acidification is to increase the amount of phosphorus available in the digestate liquid fraction and, subsequently, recover this element by chemical precipitation in the form of struvite or calcium phosphate. Two digestate samples (one fresh and one old) were studied and treated by adding various amounts of sulphuric acid to the different digestate fractions (raw digestate, solid fraction and liquid fraction). For the raw digestate, phosphorus releases higher than 95% were obtained for pH 4.0. In the last part of the experiment, the influence of acid pre-treatment on the reaction yield of phosphorus precipitation, in the form of struvite or calcium phosphate, was determined. Improvements in reaction yield were obtained up to 15% for struvite and 80% for calcium phosphate, increasing also in 7.5 times the amount of phosphorus available in the digestate liquid fraction, for both cases.

Biochar production and its use in agriculture can play a key role in climate change mitigation and help improve the quality and management of waste materials coming from agriculture and forestry. Biochar is a carbonaceous material obtained from thermal decomposition of residual biomass at relatively low temperature and under oxygen limited conditions (pyrolysis). Biochar is currently a subject of active research worldwide because it can constitute a viable option for sustainable agriculture due to its potential as a long-term sink for carbon in soil and benefits for crops. However, to date, the results of research studies on biochar effects on crop production show great variability, depending on the biochar type and experimental conditions. Therefore, it is important to identify the beneficial aspects of biochar addition to soil on crop yield in order to promote the adoption of this practice in agriculture. In this study, the effects of two types of biochar from agricultural wastes typical of Southern Spain: wheat straw and olive tree pruning, combined with different mineral fertilization levels on the growth and yield of wheat (Triticum durum L. cv. Vitron) were evaluated. Durum wheat was pot-grown for 2 months in a growth chamber on a soil collected from an agricultural field near C\u00f3rdoba, Southern Spain. Soil properties and plant growth variables were studied in order to assess the agronomic efficiency of biochar. Our results show that biochar addition to a nutrientpoor, slightly acidic loamy sand soil had little effect on wheat yield in the absence of mineral fertilization. However, at the highest mineral fertilizer rate, addition of biochar led to about 20\u201330 % increase in grain yield compared with the use of the mineral fertilizer alone. Both biochars acted as a source of available P, which led to beneficial effects on crop production. In contrast, the addition of biochar resulted in decreases in available N and Mn. A maximum reduction in plant nutrient concentration of 25 and 80% compared to nonbiochar-treated soils for N and Mn, respectively, was detected. This fact was related to the own nature of biochar: low available nitrogen content, high adsorption capacity, and low mineralization rate for N; and alkaline pH and high carbonate content for Mn. Our results indicate that biochar-based soil management strategies can enhance wheat production with the environmental benefits of global warming mitigation. This can contribute positively to the viability and benefits of agricultural production systems. However, the nutrient\u2013biochar interactions should receive special attention due to the great variability in the properties of biochar-type materials.", "keywords": ["2.

Soil inorganic P availability decreased after N addition due to the changes in both microbial properties and plant uptake.\u2022 Context Soil phosphorus (P) availability is considered an important factor in influencing the biomass production of plants. Sustained inputs of nitrogen (N) through atmospheric deposition or N fertilizers, particularly in temperate forests, may change the composition and availability of P and thus affect long-term forest productivity.\u2022 Aims The objective of this study was to assess soil P availability, P fractions, and microbial properties including microbial biomass P and acid phosphatase activity after 9 consecutive years of N addition in a larch (Larix gmelinii) plantation, northeastern China.\u2022 Methods From 2003 to 2011, NH4NO3 was added to replicate plots (three 20\u00a0m\u2009\u00d7\u200930\u00a0m plots) in the larch plantation each year at a rate of 100\u00a0kg\u00a0N\u00a0ha\u22121\u00a0year\u22121. Soil samples from 0\u201310-cm and 10\u201320-cm depths were collected in N addition plots and control (no N addition) plots.\u2022 Results N addition significantly decreased soil NaHCO3-Pi (Pi is inorganic P), microbial biomass P, and acid phosphatase activity but increased the NaOH-Pi concentration. N addition appeared to induce a decrease in soil inorganic P availability by changing pH and P uptake by trees. In addition, N addition significantly decreased the NaOH-Po (Po is organic P) concentration, possibly because of increased P mineralization. However, the total P and other P fractions were unaffected by N fertilization.\u2022 Conclusion Our results suggested that N addition enhanced P uptake by trees, whereas it reduced soil inorganic P availability as well as microbial biomass and activity related to soil P cycling in the larch plantation.", "keywords": ["[SDV] Life Sciences [q-bio]", "2.

However, no differences were found in N2 fixation between mild and severe FTCs, but N2 fixation in mosses from the temperate heath was less susceptible to FTCs than those from colder sites, suggesting adapted temperate diazotroph communities. Mosses lost little N, most at constant, positive temperatures, while more phosphate was lost from mosses exposed to FTCs, depending on the positioning along the climate gradient, mirroring nutrient demand and limitation.

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.

Grazing reduced aboveground biomass, foliar P and N stocks by 45%, 38% and 45%, respectively, compared to ungrazed plots, although the foliar P concentration was 20% greater in grazed plots.

The French Soil Quality Monitoring Network (RMQS) is a national program for the assessment and long-term monitoring of the quality of French soils. This network is based on the monitoring of 2240 sites representative of French soils and their land use. These sites are spread over the whole French territory (metropolitan and overseas) along a systematic square grid of 16 km x 16 km cells. The network covers a broad spectrum of climatic, soil and land-use conditions (croplands, permanent grasslands, woodlands, orchards and vineyards, natural or scarcely anthropogenic land and urban parkland). The physical, chemical and biological properties of the soil are measured on each site. These soil analyses were carried out by the Soil Analysis Laboratory of INRAE (Arras, France). The spatial and temporal variability of soil properties are explained by biophysical variables, sources of contamination, history of land-use and management practices on each plot. The first sampling campaign in metropolitan France took place from 2000 to 2009 and the second campaign has begun in 2016. At each site, 25 core samples were taken by layer with an auger within a 20 m \u00d7 20 m plot and combined into a composite sample. Analyses used in this study only concern the surface layer (generally 0\u201330 cm layer) of samplings from the first campaign in metropolitan France. The dataset published contains all the raw data used in the statistical analysis in order to make them available for any further study.

The soil used was chromosol and the applied wastewater sludge biochar was 10tha(-1). The results showed that the application of biochar improves the production of cherry tomatoes by 64% above the control soil conditions. The ability of biochar to increase the yield was attributed to the combined effect of increased nutrient availability (P and N) and improved soil chemical conditions upon amendment. The yield of cherry tomato production was found to be at its maximum when biochar was applied in combination with the fertiliser. Application of biochar was also found to significantly increase the soil electrical conductivity as well as phosphorus and nitrogen contents.

However, its use is associated with emissions of ammonia (NH(3)), nitrous oxide (N(2)O) and nitric oxide (NO), which have both economic and environmental impact. Urease activity inhibitors have been proposed as a means to reduce NH(3) emissions, although limited information exists about their effect on N(2)O and NO emissions. In this context, a field experiment was carried out with a barley crop (Hordeum vulgare L.) under Mediterranean conditions to test the effectiveness of the urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT) on reducing these gaseous N losses from surface applied urea. Crop yield, soil mineral N concentrations, dissolved organic carbon (DOC), denitrification potential, NH(3), N(2)O and NO fluxes were measured during the growing season. The inclusion of the inhibitor reduced NH(3) emissions in the 30 d following urea application by 58% and net N(2)O and NO emissions in the 95 d following urea application by 86% and 88%, respectively. NBPT addition also increased grain yield by 5% and N uptake by 6%, although neither increase was statistically significant. Under the experimental conditions presented here, these results demonstrate the potential of the urease inhibitor NBPT in abating NH(3), N(2)O and NO emissions from arable soils fertilized with urea, slowing urea hydrolysis and releasing lower concentrations of NH(4)(+) to the upper soil layer.", "keywords": ["2.

Dissolved organic matter (DOM) plays a central role in driving soil biogeochemistry, but little information is available on the effects of plastic residues, especially microplastic, on soil DOM. We conducted a soil-incubation experiment in a climate-controlled chamber with three levels of microplastic added to loess soil collected from the Loess Plateau in China: 0% (control, CK), 7% (M1) and 28% (M2) (w/w). We analysed the soil contents of dissolved organic carbon (DOC), dissolved organic nitrogen (DON), NH4+, NO3-, dissolved organic phosphorus (DOP), and PO43- and the activities of fluorescein diacetate hydrolase (FDAse) and phenol oxidase. The higher level of microplastic addition significantly increased the nutrient contents of the DOM solution. The lower level of addition had no significant effect on the DOM solution during the first seven days, but the rate of DOM decomposition decreased in M1 between days 7 and 30, which increased the nutrient contents. The microplastic facilitated the accumulation of high-molecular-weight humic-like material between days 7 and 30. The DOM solutions were mainly comprised of high-molecular-weight humic-like material in CK and M1 and of high-molecular-weight humic-like material and tyrosine-like material in M2. The Microplastic stimulated the activities of both enzymes.

In this study, a novel decision support tool (DST) was developed, which brought all these factors together in one place for five nutrient scenarios. A systematic literature review was conducted to create a database containing 75 media with an associated static scoring system across seven criteria (% of nutrient concentration reduction, removal of other pollutants, lifetime, hydraulic conductivity, negative externalities) and a dynamic scoring system across two criteria (delivery cost and availability). The DST was tested using case studies from Ireland, Belgium and USA with different agricultural practices and nutrient scenarios. It was then validated by SWOT (strength, weakness, opportunities and threats) analysis. The DST provided a rapid, easily modifiable screening of many media-based treatments for specific dual or single nutrient-based water drainage problems.

To address this question, common bean (Phaseolus vulgaris L. cv. El Djadida) and maize (Zea mays L. cv. Filou), were grown as sole- and inter-crops in two experimental sites; S1 (P-deficient) and S2 (P-sufficient) during two growing seasons (2011 and 2012). Growth, nodulation and grain yield were assessed and correlated with the rhizosphere soil P availability. Results showed that P availability significantly increased in the rhizosphere of both species, especially in intercropping under the P-deficient soil conditions. This increase was associated with high efficiency in use of the rhizobial symbiosis (high correlation between plant biomass and nodulation), plant growth and resource (nitrogen (N) and P) use efficiency as indicated by higher land equivalent ratio (LER > 1) and N nutrition index (for maize) in intercropping over sole cropping treatments. Moreover, the rhizosphere P availability and nodule biomass were positively correlated (r2 = 0.71, p < 0.01 and r2 = 0.62, p < 0.01) in the intercropped common bean grown in the P-deficient soil during 2011 and 2012. The increased P availability presumably improved biomass and grain yield in intercropping, though it mainly enhanced grain yield in intercropped maize. Our findings suggest that modification in the intercropped common bean rhizosphere-induced parameters facilitated P uptake, plant biomass and grain yield for the intercropped maize under P-deficiency conditions.", "keywords": ["[SDV.SA]Life Sciences [q-bio]/Agricultural sciences", "580", "2.

In combination with changing production scenarios as a result of climate change, this means an improved understanding is needed of how low nutrient availability and climatic stress factors affect yields and yield stability.We examined the long-term effects mineral and organic fertilisation on a nutrient-depleted field, and observed large annual variations: depending on the year, average spring barley yields under unfertilised management (U) were between 17-75% lower than the reference N1/2P1/2K1/2 (60-10-60 kg ha(-1)). Yields increased up to 174% under N1P1K1 (120-20-120 kg ha(-1)), while animal manure applications at an N availability level corresponding to N-1 were between 79 and 137%. No temporal yield trends could be observed, but long-term changes of Olsen-P and exchangeable K were related to the nutrient balances (inputs-offtake) (r(2) = 0.60 and 0.59, respectively, P < 0.001).Multiple linear regression analysis was used to examine the effects of the treatments in combination with annual weather variations. The results could be split into two outcomes, 1) a general relation between yields and temperatures for the periods of early spring (P < 0.01, multiple R-2 = 0.31) and summer (P < 0.001, multiple R-2 =0.45), and 2) an interaction between temperature and nutrient applications during crop establishment, leading to a diverse response of relative yields (P < 0.001 multiple R-2 =0.64), i.e. relative yield losses under the unfertilised treatment (U) were greater in years with lower spring temperatures, and, conversely, the increased nutrient availability in the fully mineral and organically fertilised treatments could partially alleviate the negative effects.After 13 years of repeated fertilisation, inputs were suspended for a single year and only N was applied to evaluate the residual effects. Yields were significantly affected by the different fertilisation histories (P < 0.001). Likewise, apparent nitrogen recovery tended to improve with previous inputs, but the observations were highly variable.Overall, the analyses agree with the notion that brief periods of stress at a critical stage may significantly affect yields, and confirmed that management of sufficient nutrient availability is critical for maintaining high and stable yields.

The Quesungual slash-and-mulch agroforestry system (QSMAS) of western Honduras offers a promising alternative to traditional slash-and-burn (SB) agriculture for the mountainous tropical dry forest zones of Central America, but the overall influence of this system on soils is not fully understood. We examined earthworm populations, soil fertility and soil organic matter (SOM) dynamics under QSMAS and SB agriculture, with secondary forest (SF) as a reference. Both QSMAS and SB consisted of treatments with and without inorganic fertilizer (N\u2013P\u2013K) additions, resulting in five management treatments, each present on three replicate farms. Baseline soil samples (0\u201315\u00a0cm) were collected prior to forest clearing and establishment of QSMAS plots in 2003 and in SB and SF plots in 2005 to determine initial soil concentrations of C and N. Soils were sampled in 2006 and 2007 for bulk soil C and N and P availability, as well as for aggregate fractionation and determination of C and N within the different aggregate size fractions. Earthworm populations were assessed in July 2007. Earthworm numbers and biomass were higher under QSMAS than under SB (13.4 vs. 0.8\u00a0g fresh biomass m \u2212\u00a02 ; respectively). Significant interactions between cropping system and fertilization suggest that QSMAS increased the availability of added inorganic P, 3 times more under QSMAS than for SB. Comparisons with SF, indicated that both cropping systems resulted in a dramatic loss of C (average 5\u00a0g\u00a0C\u00a0kg \u2212\u00a01 soil) since treatment implementation, and that this loss was mainly associated with the disruption of C rich large macroaggregates (>\u00a02000\u00a0\u00b5m). After taking into account baseline soil C differences between plots, no major differences in total SOM losses were found between QSMAS and SB management. However, earlier establishment of QSMAS plots suggests that the overall rate of C loss since treatment establishment was lower for QSMAS than for SB. Results from this study suggest that the Quesungual agroforestry system offers great potential to improve soil fertility and biological health in the region relative to traditional slash-and-burn agriculture.", "keywords": ["2.

The factors that govern nutrient retention and cycling in VFS are complex and act in all three dimensions. A key element that determines VFS effectivity is flow type, e.g., sheet vs. concentrated flow. These aspects are, however, often insufficiently accounted for in VFS research and design recommendations. In this study, we attempt to tackle these shortcomings by examining the nutrient distribution in detail at two field-VFS transitions, applying a three-dimensional sampling array together with extensive laboratory analyses. Concentrated runoff was the dominant type we found and we argue that flow convergence is the norm rather than the exception. Further complicating this issue is that entry locations of runoff may vary, calling for more sophisticated sampling designs. Overall trends were similar across the analyzed nutrient fractions (different K- and P-pools) and there were distinct trends of decreasing nutrients along the longitudinal (from the field to the VFS) and vertical planes. The horizontal plane (from outside to inside the area of concentrated flow) showed mostly inconclusive or U-shaped gradients. Both sites were similar and close to each other, nevertheless, there were significant differences that affected nutrient retention in the VFS which were linked to site-specific factors. The spatial extent (i.e., width) is often considered the main variable in VFS designs. However, other VFS traits such as vegetation type and structure, as well as external factors such as field topography and the severity of erosive events are equally important and should be attributed more significance.", "keywords": ["Phosphorus", "Agriculture", "15.

The Fe in the crystal structure of vivianite can be substituted by other divalent metal cations such as Mn2+ or Mg2+. Since Mg is much more abundant in coastal porewaters than Mn, the more frequent reports of Mn substitution in vivianites of coastal sediments has been suggested to indicate a preferential incorporation of Mn over Mg into the crystal structure of vivianite. However, although both Mn and Mg substitution in vivianite are environmentally relevant, it is yet unknown whether Mn or Mg is preferentially incorporated and how these isomorphic substitutions alter the crystal structure and morphology of vivianite, parameters which may influence vivianite reactivity. Here, we studied the incorporation of Mn and/or Mg in vivianites formed by co-precipitation at pH 7 in the presence of varying dissolved Mn and/or Mg concentrations and solution salinities resembling an estuarine gradient from 0 to 9 psu. In total, 19 different vivianites were synthesized, with up to 50% of Fe substituted by Mn and Mg. Thermodynamic equilibrium calculations showed that aqueous Mg speciation was altered with increasing salinity, while Mn speciation was less affected, likely explaining the preferential incorporation of Mn in the vivianite structure at higher salinities. 57Fe-M\u00f6ssbauer spectroscopy revealed that both Mn and Mg were preferentially incorporated in the double-octahedral Fe position, at which intervalence charge transfer is possible during the oxidation of vivianite. In contrast to Mg, which is redox inactive, incorporated Mn can participate in heteronuclear intervalence charge transfer with Fe. Thus, incorporation of either cation may impact the reactivity of vivianite under oxidizing conditions in element specific ways. Results of complementary analyses including X-ray diffraction, electron microscopy and Fe K-edge X-ray absorption spectroscopy further showed that incorporation of Mn and/or Mg led to smaller particle size, increased crystal roughness and thinner crystals, as well as systematic changes in unit cell parameters. These observed changes in crystal morphology might impact the reactivity of vivianite in natural environments and thus the effect of cation incorporation in vivianite should be considered when studying Fe and P cycling in coastal sediments.", "keywords": ["M\u00f6ssbauer Spectroscopy", "550", "Isomorphic substitution", "13.

We demonstrate the suitability of SRXCT for observing the root system of wheat plants growing in two soils (Calcisol and Ultisol) in response to placement of different phosphorus fertilisers. To optimize scanning quality, we tested the use of an inverse \u2018mask\u2019 in front of the soil cores to achieve a more uniform attenuation along the sample, thereby avoiding saturation of the detector along the thinnest parts of the soil cores. Secondly, we developed a deep learning approach for segmentation and quantification of root length and diameter.

The lightly grazed sites had significantly higher herbaceous diversity, total abundance, basal cover and aboveground biomass, and a lower percentage of bare ground compared with the heavy grazed sites. Grazing pressure had no effect on the density and number of woody species as well as on the proportion of encroaching woody species. The light grazing sites had higher organic carbon, phosphorus and exchangeable bases, and therefore a higher pH and higher electrical conductance, indicating an improved soil nutrient status compared with heavy grazing sites, mainly attributed to the higher basal cover and standing biomass at light grazed sites, and the export of nutrients through grazing and dung collection from the heavily grazed sites. There were significantly higher soil nutrients, species diversity, aboveground biomass and basal cover in the light grazing sites compared with heavy grazing sites.

Near to Kuruman, commercial farms have practiced rotational grazing for decades. In communal areas of former homeland Bophuthatswana, similar strategies were used prior to 1994. Nowadays, a continuous grazing system is common. We hypothesized that these changes in management affected soil properties. To test this, we sampled soils at communal and commercial land along a gradient with increasing distance to water points. The results revealed that communal systems with continuous grazing showed enlarged spatial gradients. The soils were depleted in most nutrients close to the water relative to those of commercial systems. In contrast, as the distance to the water increased, the nutrient stocks of these communal systems were higher. Changes in soil nutrient stocks were related to a zone of increased bush encroachment (up to 25%). Specific analyses (phosphorus fractions, particulate organic carbon, \u03b413C) confirmed that the soils of the communal grazing systems benefited from the shift of grass-dominated to bush-dominated system with woody Acacia vegetation, while the rangeland degraded in the sense that it lost palatable grass species.", "keywords": ["Continuous grazing", "0106 biological sciences", "2.

The effects of tillage and crop rotation on soil physico-chemical properties, soil organic carbon (SOC) and N have been studied widely in long and short-term experiments. However, their effects on nutrient levels and fertility losses have not been extensively studied in Mediterranean soils. We determined SOC, N, P, K, Fe, Mn, Cu and Zn distribution in the soil profile and in plant uptake, on a Calciortidic Haploxeralf in Spain. Three tillage systems [CT, conventional tillage (mouldboard plow); MT, minimum tillage and NT, no tillage] and three crop rotations [BB, continuous barley (Hordeum vulgare v. Tipper), FB, fallow-barley and VB, vetch (Vicia sativa v. Muza)-barley] were compared. SOC and N were higher for CT than for MT and NT in the first year, but higher for NT and MT than CT in the next years. In the 0-15 cm depth, SOC and N in NT also became higher than in MT for the fourth crop season. In the 15-30 depths, NT and MT had also higher SOC than CT since the second year. However, NT had only higher N than MT after three crop seasons. The increase in SOC was 75% for NT and MT while CT had a decrease of 17% in the 0-15 cm layer. The increase in N was 154% for NT, 108% for MT and 30% for CT in the upper 15 cm. NT had higher P, K and Cu than MT and higher P, K, Fe, Mn, Cu and Zn than CT in the upper layers due to the higher SOC level and to the fact that these systems maintain surface-applied K and P fertilizer. On the other hand, neither SOC nor N were affected by crop rotation. Tillage and rotation interactions were not significant for SOC, N and, in general, nutrient levels in the different soil depths. In general, the main factor that affected SOC, N and nutrients was tillage, which had reduced influence with depth. Highest yield was for CT-FB and CT-VB, but not different from NT-FB and NT-VB, meanwhile highest nutrient levels were obtained for interactions that included NT. These results suggest that NT, and to a lesser extend MT, preserved SOC and nutrient levels in the upper layers and, with NT-VB and NT-FB interaction, could also obtain high yields and keep soil fertility in the upper depths during the first 4 years. \u00a9 2006 Elsevier B.V.

In this study, a decision support tool was used to identify appropriate media that may be placed in filters for the removal of DRP and NH4. The selected media for this study were sand and zeolite. Both media were placed in acrylic tubes each with an internal diameter of 0.01 m and with lengths ranging from 0.1 to 0.4 m, and their performance for simultaneous removal of DRP and NH4 (1 mg DRP and NH4-N L\u22121) from water was evaluated. The data generated from the RSSCTs were used to model DRP and NH4 removals in 0.4 m-long laboratory columns of internal diameter 0.1 m, which had the same media configuration as the small columns and were operated using the same influent concentrations. The developed model successfully predicted the effluent concentration of both the DRP and NH4-N from the large columns.

Frequent reclamation of wetlands and grasslands and intensive agricultural activity have induced significant changes in both land use/cover and soil physicochemical properties in the riparian zones of the middle Heihe River basin of China. The present study aims to explore whether land use/land cover change (LUCC) can well explain the variations in soil properties in the riparian zones of the middle Heihe River basin. To achieve this, we mapped LUCC and quantified the type of land use change using remote sensing images, topographic maps, and GIS analysis techniques. Forty-two sites were selected for soil and vegetation sampling. Then, physical and chemical experiments were employed to determine soil moisture, soil bulk density, soil pH, soil organic carbon, total nitrogen, total potassium, total phosphorous, available nitrogen, available potassium, and available phosphorous. The Independent-Samples Kruskal-Wallis Test, principal component analysis, and a scatter matrix were used to analyze the effects of LUCC on soil properties. The results indicate that the majority of the parameters investigated were affected significantly by LUCC. In particular, soil moisture and soil organic carbon can be explained well by land cover change and land use change, respectively. Furthermore, changes in soil moisture could be attributed primarily to land cover changes. Changes in soil organic carbon were correlated closely with the following land use change types: wetlands-arable, forest-grasslands, and grasslands-desert. Other parameters, including pH and total K, were also found to exhibit significant correlations with LUCC. However, changes in soil nutrients were shown to be induced most probably by human agricultural activity (i.e. fertilize, irrigation, tillage, etc.), rather than by simple conversions from one land use/cover types to the others.", "keywords": ["2.

Wie P in Sedimenten gebunden ist, wirkt sich auf dessen Bioverf\u00fcgbarkeit aus. Unter reduzierenden, sulfid-freien Bedingungen kann das eisenhaltige Phosphatmineral Vivianit eine wesentliche Rolle bei der P-Bindung in K\u00fcstensedimenten spielen und somit die Wasserqualit\u00e4t positiv beeinflussen. Trotz der Bedeutung von Vivianit f\u00fcr die Regulierung der P-Verf\u00fcgbarkeit in K\u00fcstensedimenten sind die in-situ Bildung, Zusammensetzung und Stabilit\u00e4t von Vivianit nur unzureichend untersucht. In dieser Doktorarbeit wurden Feldexperimente mit einer Laborstudie kombiniert, um die Bildungs- und Umwandlungsprozesse von Vivianit in gezeitenbeeinflussten Sedimenten und den Einfluss der isomorphen Substitution auf diese Prozesse aufzudecken. Diese Erkenntnisse bieten wertvolle Einblicke in die Prozesse des P-Kreislaufs in K\u00fcstensedimenten und sind bedeutend f\u00fcr die Entwicklung industrieller Anwendungen, die darauf abzielen, den anthropogenen P-Kreislauf zu schlie\u00dfen. Im ersten Teil der Arbeit wurde eine Methode entwickelt, bei der isotopisch 57Fe-markiertes Ferrihydrit mit dem Sediment vermischt wurde, um die Vivianitbildung in-situ in gezeitenbeeinflussten Sedimenten zu verfolgen. Mit dieser Methode konnte gezeigt werden, dass sich Vivianit innerhalb von sieben Wochen in gezeitenbeeinflussten Sedimenten mit g\u00fcnstigen geochemischen Bedingungen bilden kann. Die Adsorption von Phosphat an Ferrihydrit war ein wesentlicher Vorl\u00e4ufer f\u00fcr die Bildung von Vivianit. Die reduktive Aufl\u00f6sung des Ferrihydrits bildete wahrscheinlich lokale Bedingen, welche n\u00f6tig waren, um die Vivianitbildung auszul\u00f6sen. W\u00e4hrend das gebildete Vivianit nur ein kleiner Teil des Eisen (Fe)-Pools war (bis zu 15%), machte es bis zu 72% des P-Pools aus basierend auf st\u00f6chiometrischen Berechnungen. Diese Ergebnisse zeigen, dass Vivianit eine entscheidende Rolle bei der Regulierung der P-Retention in K\u00fcstensedimenten spielen kann. In der Umwelt enth\u00e4lt Vivianit h\u00e4ufig andere zweiwertige Kationen, wie Mangan (Mn) und Magnesium (Mg), die in der Kristallstruktur Fe ersetzen. Im zweiten Experiment wurde untersucht, ob Mn oder Mg bei unterschiedlichen Salzgehalten bevorzugt eingebaut wird und wie die isomorphe Substitution die Kristallstruktur und Morphologie ver\u00e4ndert. Die Synthese von neunzehn Vivianiten mit unterschiedlichen Mn- und/oder Mg-Konzentrationen bei verschiedenen Salzgehalten ergab, dass bei niedriger Ionenst\u00e4rke sowohl Mn als auch Mg Fe in der Kristallstruktur gleichwertig ersetzen k\u00f6nnen, wobei Mn bei h\u00f6herer Ionenst\u00e4rke bevorzugt wurde. Vivianit weist zwei unterschiedliche Fe-Atompositionen auf. Die Substitution von Fe durch Mn und/oder Mg fand vorzugsweise an der Atomposition statt, welche Elektronentransfer ausf\u00fchren kann, wodurch Vivianit gegen Oxidation stabilisiert wird. Somit kann sich die isomorphe Substitution wahrscheinlich direkt auf das Oxidationsverhalten von Vivianit auswirken. Au\u00dferdem f\u00fchrte die isomorphe Substitution zu kleineren, raueren Kristallen mit geringerer Kristallinit\u00e4t. Diese beobachteten Ver\u00e4nderungen k\u00f6nnten sich auf die Reaktivit\u00e4t von Vivianit in der Umwelt auswirken, weshalb die isomorphe Substitution bei der Untersuchung der Reaktivit\u00e4t von Vivianit ber\u00fccksichtigt werden sollte. Umweltver\u00e4nderungen, einschlie\u00dflich des Anstiegs des Meeresspiegels, k\u00f6nnten die Bildung von Sulfid in derzeit nicht sulfidischen Sedimenten, die Vivianit enthalten, verst\u00e4rken und zu thermodynamisch instabilen Bedingungen f\u00fcr Vivianit f\u00fchren. Das letzte Experiment untersuchte die in-situ Stabilit\u00e4t von unsubstituiertem und Mn-Mg-substituiertem Vivianit, gemischt mit Meeressand und mit oder ohne die Zugabe von Kalziumkarbonat. Die Mischungen wurden 56 Tage lang in zwei Gezeitenzonen inkubiert, von denen ein Standort eine niedrige und der andere eine hohe Sulfidkonzentration aufwies. Die Inkubation von unsubstituiertem und Mn-Mg-substituiertem Vivianit bei unterschiedlichen Sulfidkonzentrationen ergab eine teilweise Aufl\u00f6sung von Vivianit, die durch die isomorphe Substitution deutlich verst\u00e4rkt wurde. Der gr\u00f6\u00dfte Teil der verbleibenden Mineralphase wurde weiterhin als Vivianit charakterisiert, was darauf hindeutet, dass ein Teil des Vivianits \u00fcber die Versuchsdauer erhalten blieb. Bei niedrigen Sulfidkonzentrationen war Gr\u00fcner Rost das Hauptumwandlungsprodukt, das wahrscheinlich einen Teil des freigesetzten Phosphats adsorbierte. Bei hohem Sulfidgehalt dominierte die Bildung von Fe-Sulfidmineralen, welche aufgrund der geringen Sorptionskapazit\u00e4t f\u00fcr Phosphat zu einem erh\u00f6hten P-Verlust f\u00fchrte. Ein erh\u00f6htes Sorptionspotenzial f\u00fcr Phosphat durch die Zugabe von Kalziumkarbonat k\u00f6nnte den Phosphatverlust geringf\u00fcgig verringern. Diese Ergebnisse zeigen, dass vivianithaltige Sedimente als Quelle f\u00fcr bioverf\u00fcgbares Phosphat dienen k\u00f6nnen, wenn sich die geochemischen Bedingungen \u00e4ndern. Diese Arbeit liefert neue experimentelle Ans\u00e4tze zur Untersuchung und Quantifizierung von Umwandlungs- und Bildungsprozessen von Vivianit. Die Ergebnisse zeigen eine schnelle in-situ Bildungskinetik, w\u00e4hrend die Aufl\u00f6sung von Vivianit unter den untersuchten Bedingungen langsam verl\u00e4uft. Die schnelle in-situ Bildungskinetik deutet darauf hin, dass die Vivianitbildung die P-Retention in Umgebungen mit sowohl schwankenden als auch stabilen geochemischen Bedingungen regulieren kann. Die Ver\u00e4nderungen der Kristallstruktur und -morphologie durch isomorphe Substitution erh\u00f6hten das Ausma\u00df der Aufl\u00f6sung und Umwandlung des Vivianits. Aufgrund der langsamen in-situ Aufl\u00f6sung k\u00f6nnte Vivianit bei kurzfristigen Umweltst\u00f6rungen eine stabile P-Retentionsphase darstellen. Langfristig destabilisierende Bedingungen k\u00f6nnten jedoch zu einer vollst\u00e4ndigen Aufl\u00f6sung f\u00fchren und die P-Retentionskapazit\u00e4t des Sediments schw\u00e4chen. Die Ergebnisse unterstreichen die Bedeutung von Vivianit als P-Retentionsphase in salzarmen K\u00fcstensedimenten, k\u00f6nnten aber auch f\u00fcr das Verst\u00e4ndnis von Bildungs- und Umwandlungsprozessen von Vivianit in anderen Umweltsystemen, wie limnischen Sedimenten und B\u00f6den in Feuchtgebieten, von Bedeutung sein.

The objective of this study was to examine how P-acquisition strategies of three main crops are affected by the application of sewage sludges, compared with a mineral P fertilizer. We carried out a 3-months greenhouse pot experiment and compared the response of P-acquisition traits among wheat, barley and canola in a soil amended with three sludges or a mineral P fertilizer. Results showed that the P-acquisition strategy differed among crops. Compared with canola, wheat and barley had a higher specific root length and a greater root carboxylate release and they acquired as much P from sludge as from mineral P. By contrast, canola shoot P content was greater with sludge than with mineral P. This was attributed to a higher root-released acid phosphatase activity which promoted the mineralization of sludge-derived P-organic. This study showed that contrasted P-acquisition strategies of crops allows increased use of renewable P resources by optimizing combinations of crop and the type of P fertilizer applied within the cropping system.90% DW.

In addition, changes in the length of the growing season may increase plant productivity and the\u00a0rate of labile C input below ground. We carried out an experiment in which inorganic nutrients (NH 4 NO 3 and NaPO 4 ) and organic substrates (glucose and glycine) were added to soils sampled from across the mountain birch forest-tundra heath ecotone in northern Sweden (organic and mineral soils from the forest, and organic soil only from the heath). Carbon dioxide production was then monitored continuously over the following 19 days. Neither inorganic N nor P additions substantially affected soil respiration rates when added separately. However, combined N and P additions stimulated microbial activity, with the response being greatest in the birch forest mineral soil (57% increase in CO 2 production compared with 26% in the heath soil and 8% in the birch forest organic soil). Therefore, mineralisation rates in these soils may\u00a0be stimulated if the overall nutrient availability to microbes increases in response to global change, but N deposition alone is unlikely to enhance decomposition. Adding either, or both, glucose and glycine increased microbial respiration.

These positive \u2018priming\u2019 effects were lost following N addition in forest mineral soil, and following both N and P additions in the heath soil.

A split plot design with four replications was laid-out on a loamy-sand Ferric Lixisol with till and no-till as main treatments and fertiliser types as sub-treatments. Soil was fractionated physically into coarse (0.250\u20132 mm), medium (0.053\u2013 0.250 mm) and fine fractions (< 0.053 mm). Particulate organic carbon (POC) accounted for 47\u201353% of total soil organic carbon (SOC) concentration and particulate organic nitrogen (PON) for 30\u201337% of total soil nitrogen concentration. The POC decreased from 53% of total SOC in 2000 to 47% of total SOC in 2001. Tillage increased the contribution of POC to SOC. No-till led to the lowest loss in SOC in the fine fraction compared to tilled plots. Well-decomposed compost and single urea application in tilled as well as in no-till plots induced loss in POC. Crop N uptake was enhanced in tilled plots and may be up to 226 kg N ha \ufffd 1 against a maximum of 146 kg N ha \ufffd 1 in no-till plots. Combining crop residues and urea enhanced incorporation of new organic matter in the coarse fraction and the reduction of soil carbon mineralisation from the fine fraction. The PON and crop N uptake are strongly correlated in both till and no-till plots. Mineral-associated N is more correlated to N uptake by crop in tilled than in no-till plots. Combining recalcitrant organic resources and nitrogen fertiliser is the best option for sustaining crop production and reducing soil carbon decline in the more stabilised soil fraction in the semi-arid West Africa. # 2005 Published by Elsevier B.V.", "keywords": ["2.

Microorganisms, when stimulated by the presence of new inputs of labile organic carbon, can mineralize (\u2018prime\u2019) soil organic matter to acquire nutrients. We used stable carbon isotopes to assess how nutrient demand and soil properties constrain mineralization of added labile (sucrose) carbon and pre-existing (primed) soil carbon in tropical forest soils. In a series of lowland tropical forest soils from Panama, we found that the mineralization of fresh labile carbon was accelerated foremost by phosphorus addition, whereas the mineralization of pre-existing soil carbon was constrained foremost by nitrogen addition. However, there was variation in the relative importance of these nutrients in different soils and the largest effects on the acceleration of sucrose metabolism and constraint of priming occurred following the addition of nitrogen and phosphorus together. The respiration responses due to sucrose or primed soil carbon mineralization were reduced at pH below 4.8 and above 6.0. We conclude that in these tropical forest soils, phosphorus availability is more important in promoting microbial mineralization of sucrose carbon, whereas nitrogen availability is more important in constraining the priming of pre-existing soil organic carbon. This response likely arises because nitrogen is more closely coupled to organic matter cycling, whereas phosphorus is abundant in both organic and inorganic forms. These results suggest that the greatest impact of priming on soil carbon stocks will occur in moderately acidic tropical forest soils of low nitrogen availability. Given long-term changes in both atmospheric carbon dioxide and nitrogen deposition, the impact of priming effects on soil carbon in tropical forest soils may be partially constrained by the abundance of nitrogen.", "keywords": ["2.

Here we investigated the effects of different N, P and NP fertilizer levels (4 N levels without P; 4 P levels without N; and 4 P levels with constant N addition) on the abundances of 9 microbial groups involved in N dynamics. Real time PCR was used to target free N2 fixers, nitrifiers (bacterial and archaea ammonia oxidizers, AOB and AOA, respectively; and the nitrite oxidizers Nitrobacter and Nitrospira), nitrate reducers, nirK- and nirS-nitrite reducers, and nitrous oxide reducers. Soil physical-chemical characteristics and potential nitrification, PNR, were also measured. N fertilization increased the abundances of AOB and Nitrobacter but did not affect the abundances of the other groups. P fertilization decreased the abundances of N2 fixers, nitrate reducers and AOA, and increased the abundances of Nitrobacter and nitrous oxide reducers. NP fertilization decreased the abundances of AOA and nirK-nitrite reducers. Using a correlation network analysis, we demonstrate the strong coupling generally observed in these grasslands between N2 fixers, AOA, Nitrospira, narG-nitrate reducers and nirK-denitrifiers (most of them responding to N/P availability, and being known to be favored by low oxygen availability); and between AOB and Nitrobacter (known to be favored by high oxygen and high N levels) that controlled changes in PNR.

Moreover, common theories of stoichiometric decomposition and microbial N mining predict opposing effects of N supply on SOC turnover. We hypothesized that the effect of N deposition on SOC turnover depends on initial soil nutrient conditions. Thus, we sampled tropical forests and rubber gardens with pronounced gradients of nutrient availability from the topsoil to the deep subsoil (up to 400 cm) and measured substrate-induced respiration (SIR) for 30 days in four treatments (C, CN, CP, CNP additions). A natural 13C abundance approach was conducted to quantify priming effects (PE) of the added C on SOC mineralization. For this purpose we assessed the 13CO2 isotope composition after adding a C4 sugar to the C3 soil; to correct for isotopic fractionation a treatment with C3 sugar additions served as control. We found that nutrient additions to topsoil did neither alter cumulative CO2 release within 30 days (SIRacc) nor PE (PE = 1.6, i.e., sugar additions raised the release of SOC-derived CO2 by a factor of 1.6). In the upper subsoil (30-100 cm), however, both CN and CP additions increased SIRacc (by 239% and 92%, respectively) and the PE (PE = 5.2 and 3.3, respectively) relative to the treatments that received C only (PE = 1.7), while CNP additions revealed the largest increase of SIRacc (267%) and PE (PE = 6.0). In the deep subsoil (>130 cm depth), only the CNP addition consistently increased SIRacc (by 871%) and PE (PE = 5.2) relative to only C additions (PE = 2.0). We conclude that microbial activity was not limited by nutrients in the topsoil but was co-limited by both N and P in the subsoil. The results imply that microbes mine nutrients from previously unavailable pools under the conditions that 1) deficiency actually exists, 2) co-limitation is alleviated, and 3) nutrient reserves are present. Yet, as opposed to microbial nutrient mining theories, we showed that the subsoil PE is highest when nutrient supply matches microbial demand. As a result also N deposition might exert variable effects on SOC turnover in tropical soils: it might have no effect in nutrient-rich topsoils and in co-limited subsoils without P reserves but might increase SOC turnover in co-limited subsoils with potentially acquirable P reserves.", "keywords": ["soil organic carbon", "2.

Growing plants with high P recycling capacity may increase the importance of organic forms in phosphate availability mainly in undisturbed soils. The aim of this study was to evaluate the effect of long period of cultivation of different winter species under different soil management systems in the distribution of soil organic P forms, in the P content stored into the soil microbial biomass (SMB) and in the acid phosphatase enzyme activity. The experiment was established in 1986 with six winter treatments (blue lupine, hairy vetch, oat, radish, wheat and fallow) implanted in a Rhodic Hapludox in southern Brazil, under no-tillage system (NT) and conventional tillage system (CT). The crops were cultivated with rational use of chemical phosphate fertilizer, according to plant needs and soil type maintaining high levels of soil organic carbon leading to P organic form accumulation. Growing crops during the winter period in highly weathered subtropical soil increases the importance of microbial interactions in the P cycle, especially in the NT, where a large amount of crop residues is annually added to the soil surface, increasing soil organic P level, P content stored into the SMB and acid phosphatase enzyme activity.", "keywords": ["2.
