These datasets are 'ready-to-use' for modeling purposes, as they include target soil properties and features in a tidy tabular format. Three target soil properties are present in every dataset: (1) soil organic matter (SOM) or soil organic carbon (SOC), (2) pH, and (3) clay content, while the features for modeling are dataset-specific. The primary goal of `LimeSoDa` is to enable more reliable benchmarking of machine learning methods in digital soil mapping and pedometrics. All the associated materials and data from LimeSoDa can be downloaded in this data repository.

We do provide cross validation (CV) accuracy plots in this repository for both the overall sample (_CV_plots.tif). These plots compare CV predictions with observed values relative to a 1:1 line. Values plotted near the 1:1 line are more accurate. Note that values are plotted in hex-bin density scatter plots because of the large number of observations (most are &gt;3000). Predictions are also evaluated with the U.S. soil survey laboratory database soil organic carbon (SOC) data. The SOC measurements were coverted to OM matter values using the common 1.724 conversion factor. The converted OM values are compared to predicted OM values using an accuracy plot (OM_SOC_plots.tif).

The _bt indicates that the map has been back transformed from ln or sqrt transformation used in modeling. The following elements may also exist on the end of filenames indicating other spatial files that characterize a given model's uncertainty (see below). _95PI_h: Indicates the layer is the upper 95% prediction interval value. _95PI_l: Indicates the layer is the lower 95% prediction interval value. _95PI_relwidth: Indicates the layer is the 95% relative prediction interval (RPI). The RPI is a standardization of the prediction interval that indicates that model is constraining uncertainty relative to the original sample. RPI values less than one represent uncertainty is being improved by the model relative to the original sample, and values less than 0.5 indicate low uncertainty in predictions.

However, little is known about how modifications of the diversity of soil microbial communities induced by fresh organic matter (FOM) inputs can regulate carbon cycling. Here, we investigated the decomposition of two 13C labeled crop residues (wheat and alfalfa) and the dynamics of the genetic structure and taxonomic composition of the soil bacterial communities decomposing 13C labeled FOM and native unlabeled soil organic matter (SOM), respectively. It was achieved by combining the stable isotope probing method with molecular tools (DNA genotyping and pyrosequencing of 16S rDNA). Although a priming effect (PE) was always induced by residue addition, its intensity increased with the degradability of the plant residue. The input of both wheat and alfalfa residues induced a rapid dynamics of FOM-degrading communities, corresponding to the stimulation of bacterial phyla which have been previously described as copiotrophic organisms. However, the dynamics and the identity of the bacterial groups stimulated depended on the residue added, with Firmicutes dominating in the wheat treatment and Proteobacteria dominating in the alfalfa treatment after 3\u00a0days of incubation. In both treatments, SOM-degrading communities were dominated by Acidobacteria, Verrucomicrobia, and Gemmatimonadetes phyla which have been previously described as oligotrophic organisms. An early stimulation of SOM-degrading populations mainly belonging to Firmicutes and Bacteroidetes groups was observed in the alfalfa treatment whereas no change occurred in the wheat treatment. Our findings support the hypothesis that the succession of bacterial taxonomic groups occurring in SOM- and FOM-degrading communities during the degradation process may be an important driver of the PE, and consequently of carbon dynamics in soil.", "keywords": ["0301 basic medicine", "2.

However, many uncertainties still exist regarding which parameters drive the amplitude and the direction of the biochar priming. We conducted a quantitative analysis of 1170 groups of data from 27 incubation studies using boosted regression trees (BRTs). BRT is a machine learning method combining regression trees and a boosting algorithm, which can effectively partition independent influences of various factors on the target variable in the complex ecological processes. The BRT model explained a total of 72.4% of the variation in soil carbon (C) priming following biochar amendment, in which incubation conditions (36.5%) and biochar properties (33.7%) explained a larger proportion than soil properties (29.8%). The predictors that substantially accounted for the explained variation included incubation time (27.1%) and soil moisture (5.0%), biochar C/N ratio (6.2%), nitrogen content (5.5%), pyrolysis time during biochar production (5.1%), biochar pH (4.5%), soil C content (5.2%), sand (4.7%) and clay content (4.1%). In contrast, other incubation conditions (temperature, biochar dose, whether nutrient was added), biochar properties (biochar C, feedstock type, ash content, pyrolysis temperature, whether biochar was activated) and soil properties (nitrogen content, silt content, C/N ratio, pH, land use type) had small contribution (each <\u20094%). Positive priming occurred within the first 2\u00a0years of incubations, with a change to negative priming afterwards. The priming was negative for low N biochar or in high-moisture soils but positive on their reverse sides. The size of negative priming increased with rising biochar C/N ratio, pyrolysis time and soil clay content, but deceased with soil C/N ratio.

We hypothesized that functional diversity offers a more predictive means of characterizing the impact of crop rotations on SOC concentrations than species diversity per se. Furthermore, we hypothesized that functional diversity can either increase or decrease SOC depending on its associated carbon (C) input to soil. We compiled a database of 27 cropping system sites and 169 cropping systems, recorded the species and functional diversity of crop rotations, SOC concentrations (g C kg/soil), nitrogen (N) fertilizer applications (kg\uffc2\uffa0N\uffc2\uffb7ha\uffe2\uff88\uff921\uffc2\uffb7yr\uffe2\uff88\uff921), and estimated C input to soil (Mg\uffc2\uffa0C\uffc2\uffb7ha\uffe2\uff88\uff921\uffc2\uffb7yr\uffe2\uff88\uff921). We categorized crop rotations into three broad categories: grain\uffe2\uff80\uff90only rotations, grain rotations with cover crops, and grain rotations with perennial crops. We divided the grain\uffe2\uff80\uff90only rotations into two sub\uffe2\uff80\uff90categories: cereal\uffe2\uff80\uff90only rotations and those that included both cereals and a legume grain. We compared changes in SOC and C input using mean effect sizes and 95% bootstrapped confidence intervals. Cover cropped and perennial cropped rotations, relative to grain\uffe2\uff80\uff90only rotations, increased C input by 42% and 23% and SOC concentrations by 6.3% and 12.5%, respectively. Within grain\uffe2\uff80\uff90only rotations, cereal\uffc2\uffa0+\uffc2\uffa0legume grain rotations decreased total C input (\uffe2\uff88\uff9216%), root C input (\uffe2\uff88\uff9212%), and SOC (\uffe2\uff88\uff925.3%) relative to cereal\uffe2\uff80\uff90only rotations.

Our results show that increasing the functional diversity of crop rotations is more likely to increase SOC concentrations if it is accompanied by an increase in C input. Functionally diverse perennial and cover cropped rotations increased both C input and SOC concentrations, potentially by exploiting niches in time that would otherwise be unproductive, that is, increasing the \uffe2\uff80\uff9cperenniality\uffe2\uff80\uff9d of crop rotations.</p>", "keywords": ["Crops", " Agricultural", "2.

SOC changes for the 0\uffe2\uff80\uff9320 and 0\uffe2\uff80\uff9340\uffe2\uff80\uff89cm depths varied between \uffe2\uff88\uff9225 and 42\uffe2\uff80\uff89Mg\uffe2\uff80\uff89ha\uffe2\uff88\uff921, following a normal distribution centered near zero. After replacing native vegetation by Eucalyptus plantations, mean SOC changes were \uffe2\uff88\uff921\uffc2\uffb75 and 0\uffc2\uffb73\uffe2\uff80\uff89Mg\uffe2\uff80\uff89ha\uffe2\uff88\uff921 for the 0\uffe2\uff80\uff9320 and 0\uffe2\uff80\uff9340\uffe2\uff80\uff89cm depths, respectively. These are very low figures in comparison to C stocks usually sequestered in aboveground biomass and were statistically nonsignificant as demonstrated by a t\uffe2\uff80\uff90test at p\uffe2\uff80\uff89&lt;\uffe2\uff80\uff890\uffc2\uffb705. Similar low, nonsignificant SOC changes were estimated after data were stratified into first or second rotation cycles, soil texture and biome (savanna, rainforest or grassland). Although strong SOC losses or gains effectively occurred in some cases, their underpinning causes could not be generally identified in the present work and must be ascribed in a case basis, considering the full set of environmental and management conditions. We conclude that Eucalyptus spp. plantations in average have no net effect on SOC stocks in Brazil.

Warming will also cause more precipitation to fall as rain, further enhancing the thaw of previously frozen ground. Yet, the impact of those perturbations on the geochemistry of Arctic rivers remains a subject of debate. Here, we determined the geochemical composition of waters from various contrasting non\uffe2\uff80\uff90glacial permafrost catchments and investigated their impact on a glacially dominated river, the Zackenberg River (Northeast Greenland), during late summer (August 2019). We also studied the effect of rainfall on the geochemistry of the Zackenberg River, its non\uffe2\uff80\uff90glacial tributaries, and a nearby independent non\uffe2\uff80\uff90glacial headwater stream Gr\uffc3\uffa6nse. We analyzed water properties, quantified and characterized dissolved organic matter (DOM) using absorbance and fluorescence spectroscopy and radiocarbon isotopes, and set this alongside analyses of the major cations (Ca, Mg, Na, and K), dissolved silicon (Si), and germanium/silicon ratios (Ge/Si). The glacier\uffe2\uff80\uff90fed Zackenberg River contained low concentrations of major cations, dissolved Si and dissolved organic carbon (DOC), and a Ge/Si ratio typical of bulk rock. Glacial DOM was enriched in protein\uffe2\uff80\uff90like fluorescent DOM and displayed relatively depleted radiocarbon values (i.e., old DOM). Non\uffe2\uff80\uff90glacial streams (i.e., tributaries and Gr\uffc3\uffa6nse) had higher concentrations of major cations and DOC and DOM enriched in aromatic compounds. They showed a wide range of values for radiocarbon, Si and Ge/Si ratios associated with variable contributions of surface runoff relative to deep active layer leaching. Before the rain event, Zackenberg tributaries did not contribute notably to the solute export of the Zackenberg River, and supra\uffe2\uff80\uff90permafrost ground waters governed the supply of solutes in Zackenberg tributaries and Gr\uffc3\uffa6nse stream. After the rain event, surface runoff modified the composition of Gr\uffc3\uffa6nse stream, and non\uffe2\uff80\uff90glacial tributaries strongly increased their contribution to the Zackenberg River solute export. Our results show that summer rainfall events provide an additional source of DOM and Si\uffe2\uff80\uff90rich waters from permafrost\uffe2\uff80\uff90underlain catchments to the discharge of glacially dominated rivers. This suggests that the magnitude and composition of solute exports from Arctic rivers are modulated by permafrost thaw and summer rain events. This event\uffe2\uff80\uff90driven solute supply will likely impact the carbon cycle in rivers, estuaries, and oceans and should be included into future predictions of carbon balance in these vulnerable Arctic systems.</p", "keywords": ["[SDV] Life Sciences [q-bio]", "550", "[SDV]Life Sciences [q-bio]", "supra-permafrost groundwater", "Zackenberg", "dissolved silicon", "dissolved organic matter", "551", "PARAFAC"]}, "links": [{"href": "https://doi.org/10.1002/ppp.2250"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Permafrost%20and%20Periglacial%20Processes", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1002/ppp.2250", "name": "item", "description": "10.1002/ppp.2250", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1002/ppp.2250"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2024-09-09T00:00:00Z"}}, {"id": "10.1016/j.foreco.2012.07.045", "type": "Feature", "geometry": null, "properties": {"updated": "2026-04-03T16:16:54Z", "type": "Journal Article", "created": "2012-08-27", "title": "The Manipulation Of Organic Residues Affects Tree Growth And Heterotrophic Co2 Efflux In A Tropical Eucalyptus Plantation", "description": "Fast-growing plantations are increasingly being established on tropical soils, where fertility is largely supported by soil organic matter (SOM) and where different management options of harvest organic residues is thought to impact the long-term sustainability of these plantations.

Three treatments were setup in 0.125 ha plots and replicated in three blocks at the harvesting of a Congolese Eucalyptus stand, resulting in an aboveground organic residue mass ranging from 0 to 6.3 kg m \ufffd 2 . The mineralization of SOM was deduced in each treatment by partitioning sources of soil CO2 effluxes using decomposition experiments and by upscaling specific root respiration. Soil CO2 effluxes were greatly affected by seasons and organic residue manipulation, although there were no significant changes in topsoil water content and topsoil temperature over most of the study period. Aboveground organic residue was the first contributor to soil CO2 efflux in the two treatments with a litter layer. Organic residue management did not significantly influence the mineralization of SOM in our study, probably due to the low quality of Eucalyptus litter, or to the hypothetical lack of dissolved organic carbon transfers from litter to soil.

The experimental approach combined the placement of labelled litter (delta13C=-37.9 per thousand ) with forest girdling in a 35-year-old Norway spruce stand, resulting in four different treatment combinations: GL (girdled, litter), GNL (girdled, no litter), NGL (not girdled, litter), and NGNL (not girdled, no litter). Monthly sampling of soil CO2 efflux and delta13C of soil respired CO2 between May and October 2002 allowed the partitioning of the flux into that derived from the labelled litter, and that derived from native soil organic matter and roots. The effect of forest girdling on soil CO2 efflux was detectable from June (girdling took place in April), and resulted in GNL fluxes to be about 50% of NGNL fluxes by late August. The presence of litter resulted in significantly increased fluxes for the first 2 months of the experiment, with significantly greater litter derived fluxes from non-girdled plots and a significant interaction between girdling and litter treatments over the same period. For NGL collars, the additional efflux was found to originate only in part from litter decomposition, but also from the decay of native soil organic matter. In GL collars, this priming effect was not significant, indicating an active role of the rhizosphere in soil priming. The results therefore indicate mutual positive feedbacks between litter decomposition and rhizosphere activity. Soil biological analysis (microbial and fungal biomass) of the organic layers indicated greatest activity below NGL collars, and we suppose that this increase indicates the mechanism of mutual positive feedback between rhizosphere activity and litter decomposition. However, elimination of fresh C input from both above- and belowground (GNL) also resulted in greater fungal abundance than for the NGNL treatment, indicating likely changes in fungal community structure (i.e. a shift from symbiotic to saprotrophic species abundance).", "keywords": ["570", "Soil ecology", "Microbial biomass", "Models", " Biological", "630", "Soil", "Biomass", "Picea", "Forest girdling; Microbial biomass; Soil CO; 2; efflux; Soil organic matter; Stable C isotopes;", "Ecosystem", "Soil Microbiology", "Soil CO2 efflux", "Feedback", " Physiological", "Soil organic matter", "Carbon Isotopes", "Fungi", "04 agricultural and veterinary sciences", "Carbon Dioxide", "15.

Although cultivation strongly affects important ecosystem processes such as biomass accumulation, soil organic matter dynamics, and nitrogen cycling, recovery of these processes after abandonment is insufficiently understood. We examined soil carbon and nitrogen pools and nitrogen dynamics for 16 plots on a central Massachusetts sand plain, over 80% of which had been cultivated and subsequently abandoned at least 40 years ago. The two youngest old-field forests, located on sites abandoned 40-60 years prior to our sampling, had the lowest mineral soil carbon content (0-15\u2009cm), 31% less than the average of unplowed soils. Soil carbon concentration and loss-on-ignition were significantly higher in unplowed soils than in all plowed soils, but these differences were offset by the higher bulk density in formerly plowed soils, leading to no significant differences in C content between plowed and unplowed soil. Soil C:N ratios were lower in formerly plowed soils (26.2) than in unplowed soils (28.0). While soil N content was not affected by land-use history or vegetation type, net N mineralization showed much greater variation. In situ August net nitrogen mineralization varied nearly 40-fold between stand types: lowest in pitch pine and white pine stands (-0.13 and 0.10\u2009kg\u2009N\u2009ha-1\u200928\u2009day-1), intermediate in scrub oak stands (0.48\u2009kg\u2009N\u2009ha-1\u200928\u2009day-1) and highest in aspen and mixed oak stands (1.34-3.11\u2009kg\u2009N\u2009ha-1\u200928\u2009day-1). Mineralization was more strongly related to present vegetation than to land-use history or soil N content. Appreciable net nitrification was observed only in the most recently abandoned aspen plot (0.82\u2009kg\u2009N\u2009ha-1\u200928\u2009day-1), suggesting that recent disturbance and residual agricultural lime stimulated nitrification. Carbon:nitrogen ratios increased and pH declined with stand age. Higher bulk density, lower loss-on-ignition and C:N ratios, and slightly lower C concentrations in the surface mineral soil are the persistent legacies of agriculture on soil properties. Short-term agricultural use and the low initial C and N concentrations in these sandy soils appear to have resulted in less persistent impacts of agriculture on soil C and N content and N cycling.", "keywords": ["0106 biological sciences", "soil-properties", "Forests", "Environmental-Sciences)", "01 natural sciences", "nitrogen", "variation-", "Soil", "Quercus", "soil-nitrogen", "nitrogen-", "cultivation-", "cycling-", "soil-organic-matter", "vegetation-history", "sandy-soils", "soil-carbon", "2.

The ability of additions of labile organic matter (green and animal manure) to improve productivity primarily by enhanced nutrient availability was contrasted with the ability of stable organic matter (biochar and sawdust) to improve productivity by enhancing SOC. Maize productivity declined by 66% during the first 35\u00a0years of continuous cropping after forest clearing. Productivity remained at a low level of 3.0\u00a0t\u00a0grain\u00a0ha-1 across the chronosequence stretching up to 105\u00a0years of continuous cultivation despite full N\u2013phosphorus (P)\u2013potassium (K) fertilization (120\u2013100\u2013100\u00a0kg ha\u22121). Application of organic resources reversed the productivity decline by increasing yields by 57\u2013167%, whereby responses to nutrient-rich green manure were 110% greater than those from nutrient-poor sawdust. Productivity at the most degraded sites (80\u2013105\u00a0years since forest clearing) increased in response to green manure to a greater extent than the yields at the least degraded sites (5\u00a0years since forest clearing), both with full N\u2013P\u2013K fertilization. Biochar additions at the most degraded sites doubled maize yield (equaling responses to green manure additions in some instances) that were not fully explained by nutrient availability, suggesting improvement of factors other than plant nutrition. There was no detectable influence of texture (soils with either 11\u201314 or 45\u201349% clay) when low quality organic matter was applied (sawdust, biochar), whereas productivity was 8, 15, and 39% greater (P\u00a0<\u00a00.05) on sandier than heavier textured soils with high quality organic matter (green and animal manure) or only inorganic nutrient additions, respectively. Across the entire degradation range, organic matter additions decreased the need for additional inorganic fertilizer N irrespective of the quality of the organic matter. For low quality organic resources (biochar and sawdust), crop yields were increasingly responsive to inorganic N fertilization with increasing soil degradation. On the other hand, fertilizer N additions did not improve soil productivity when high quality organic inputs were applied. Even with the tested full N\u2013P\u2013K fertilization, adding organic matter to soil was required for restoring soil productivity and most effective in the most degraded sites through both nutrient delivery (with green manure) and improvement of SOC (with biochar).", "keywords": ["Soil nutrients", "2.

Biocrusts are a major biotic feature of drylands and have large impacts on the C cycle, yet it is largely unknown whether they modulate the responses of POC and MAOC to climate change. Here, we assessed the effects of simulated climate change (control, reduced rainfall (RE), warming (WA), and RE\uffe2\uff80\uff89+\uffe2\uff80\uff89WA) and initial biocrust cover (low (&lt;\uffe2\uff80\uff8920%) versus high (&gt;\uffe2\uff80\uff8950%)) on the mineral protection of soil C and soil organic matter quality in a dryland ecosystem in central Spain for 9\uffc2\uffa0years.

These results suggest that the accumulation of soil C under warming treatments may be transitory in soils with low initial biocrust cover. In soils with high initial biocrust cover, climate change treatments did not affect SOC, neither POC nor MAOC fraction. Overall, our results indicate that biocrust communities modulate the negative effect of climate change on SOC, because no losses of soil C were observed with the climate manipulations under biocrusts.

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. Increment in soil carbon after afforestation of tropical savannah with Eucalyptus is therefore expected despite a rapid disappearance of the labile savannah-derived carbon because a large fraction of savannah-derived carbon is stable.", "keywords": ["P33 - Chimie et physique du sol", "0106 biological sciences", "570", "550", "SAVANNAH", "SEQUESTRATION", "ORGANIC-MATTER DYNAMICS", "01 natural sciences", "630", "zone tropicale", "PLANTATION", "[SDV.BV]Life Sciences [q-bio]/Vegetal Biology", "EUCALYPTUS", "[SDV.BV] Life Sciences [q-bio]/Vegetal Biology", "sol tropical", "savane", "http://aims.fao.org/aos/agrovoc/c_1301", "13C", "TROPICAL PLANTATION", "http://aims.fao.org/aos/agrovoc/c_3048", "CHANGEMENT D'USAGE DES TERRES", "http://aims.fao.org/aos/agrovoc/c_35657", "Eucalyptus", "http://aims.fao.org/aos/agrovoc/c_162", "CO2 EFFLUX", "FRACTIONATION", "http://aims.fao.org/aos/agrovoc/c_1811", "LAND-USE CHANGE", "04 agricultural and veterinary sciences", "CHRONOSEQUENCE", "15.

Agroforestry practices may also promote mineral N fertilization and the use of N2-fixing legumes that favor the emission of non-CO2 greenhouse gases (GHG) (N2O and CH4). The present study evaluates the net GHG balance in two adjacent coffee plantations, both highly fertilized (250 kg N ha-1 year-1): a monoculture (CM) and a culture shaded by the N2-fixing legume tree species Inga densiflora (CIn). C stocks, soil N2O emissions and CH4 uptakes were measured during the first cycle of both plantations. During a 3-year period (6-9 years after the establishment of the systems), soil C in the upper 10 cm remained constant in the CIn plantation (+0.09 \u00b1 0.58 Mg C ha-1 year-1) and decreased slightly but not significantly in the CM plantation (-0.43 \u00b1 0.53 Mg C ha-1 year-1). Aboveground carbon stocks in the coffee monoculture and the agroforestry system amounted to 9.8 \u00b1 0.4 and 25.2 \u00b1 0.6 Mg C ha-1, respectively, at 7 years after establishment. C storage rate in the phytomass was more than twice as large in the CIn compared to the CM system (4.6 \u00b1 0.1 and 2.0 \u00b1 0.1 Mg C ha-1 year-1, respectively). Annual soil N2O emissions were 1.3 times larger in the CIn than in the CM plantation (5.8 \u00b1 0.5 and 4.3 \u00b1 0.3 kg N-N2O ha-1 year-1, respectively). The net GHG balance at the soil scale calculated from the changes in soil C stocks and N2O emissions, expressed in CO2 equivalent, was negative in both coffee plantations indicating that the soil was a net source of GHG. Nevertheless this balance was in favor of the agroforestry system. The net GHG balance at the plantation scale, which includes additionally C storage in the phytomass, was positive and about 4 times larger in the CIn (14.59 \u00b1 2.20 Mg CO2 eq ha-1 year-1) than in the CM plantation (3.83 \u00b1 1.98 Mg CO2 eq ha-1 year-1). Thus converting the coffee monoculture to the coffee agroforestry plantation shaded by the N2-fixing tree species I. densiflora would increase net atmospheric GHG removals by 10.76 \u00b1 2.96 Mg CO2 eq ha-1 year-1 during the first cycle of 8-9 years.", "keywords": ["P33 - Chimie et physique du sol", "570", "571", "[SDV]Life Sciences [q-bio]", "F08 - Syst\u00e8mes et modes de culture", "http://aims.fao.org/aos/agrovoc/c_1920", "stockage", "Funders: EU CASCA project", "http://aims.fao.org/aos/agrovoc/c_24345", "01 natural sciences", "630", "agroforestry", "leguminous tree", "soil organic matter", "http://aims.fao.org/aos/agrovoc/c_7427", "andosol", "gaz \u00e0 effet de serre", "http://aims.fao.org/aos/agrovoc/c_1721", "http://aims.fao.org/aos/agrovoc/c_34841", "http://aims.fao.org/aos/agrovoc/c_1666", "http://aims.fao.org/aos/agrovoc/c_1301", "Inga", "syst\u00e8me de culture", "http://aims.fao.org/aos/agrovoc/c_35657", "0105 earth and related environmental sciences", "agroforesterie", "2.

The natural fallow system consisted of natural regrowth of mainly Chromolaena odorata shrub as fallow vegetation. The cover crop fallow system consisted of Pueraria phaseoloides, a herbaceous legume as fallow vegetation. The alley cropping system consisted of woody hedgerows of Leucaena leucocephala as fallow vegetation. The fallow lengths were 0 (continuous cropping), 1, 2 and 3 years after 1 year of maize/cassava intercropping. Biomass produced from natural fallow and cover crop fallow was burnt during the land preparation. Fertilizer was not applied throughout the study. Without fertilizer application, maize yield declined from above 3.0 t ha\u22121 to below 0.5 t ha\u22121 during 12 years of cultivation (1989\u20132000) on a land cleared from a 23-year old secondary forest. Temporal change in cassava tuber yield was erratic. Mean maize grain yields from 1993\u20132000 except for 1999 were higher in cover crop fallow system (1.89 t ha\u22121) than in natural fallow system (1.73 t ha\u22121), while natural fallow system outperformed alley cropping system (1.46 t ha\u22121). During the above 7 years, mean cassava tuber yield in cover crop system (7.7 t ha\u22121) did not differ from natural fallow system (8.2 t ha\u22121), and both systems showed higher cassava tuber than the alley cropping system (5.7 t ha\u22121). The positive effect of fallowing on crop yields was observed for both crops in the three systems, however, insignificant effects were seen when fallow length exceeded 1 year for cover crop and alley cropping, and 2 years for natural fallow. Soil pH, organic carbon, available P and exchangeable Ca, Mg and K decreased considerably after 12 years of cultivation, even in a 3-year fallow subplot. After 12 years, soil organic carbon (SOC) within 0\u20135 cm depth in alley cropping (13.9 g kg\u22121) and natural fallow (13.7 g kg\u22121) was higher than in cover crop fallow (11.6 g kg\u22121). Whereas significant increase in SOC with either natural fallow or alley cropping was observed only after 2 or 3 years of fallow, the SOC in the 1-year fallow alley cropping subplot was higher than that in continuous cropping natural fallow subplot. It can be concluded from our study that in transforming shifting cultivation to a permanent cropping, fallow with natural vegetation (natural fallow), herbaceous legumes (cover crop fallow) and woody legumes (alley cropping) can contribute to the maintenance of crop production and soil fertility, however, length of fallow period does not need to exceed 2 years. When the fallow length is reduced to 1 year, a better alternative to natural regrowth fallow would be the cover crop for higher maize yield and alley cropping for higher soil organic matter. For fallow length of 2 years, West African farmers would be better off with the natural fallow system.", "keywords": ["0106 biological sciences", "2.

Our results showed a rapid SOM decrease in the first few months after the conversion. The bulk chemical composition as seen by solid-state 13C NMR spectroscopy was similar under grassland and arable land, whereas different landuse had an impact on the contribution of plant litter compounds to SOM. SOM of arable soil had higher lignin contents and lower contents of non-cellulosic neutral carbohydrates than grassland soil. After grassland conversion, the most prominent change was an increase of the SOM\u2019s content of non-cellulosic carbohydrate above the contents recorded for grassland or arable land. Principal component analysis indicated that SOM chemical characteristics of converted grassland even after 2 years are similar to those of initial grassland.

A meta-analysis", "description": "The combined application of organic resources (ORs) and mineral fertilizers is increasingly gaining recognition as a viable approach to address soil fertility decline in sub-Saharan Africa (SSA). We conducted a meta-analysis to provide a comprehensive and quantitative synthesis of conditions under which ORs, N fertilizers, and combined ORs with N fertilizers positively or negatively influence Zea mays (maize) yields, agronomic N use efficiency and soil organic C (SOC) in SSA. Four OR quality classes were assessed; classes I (high quality) and II (intermediate quality) had >2.5% N while classes III (intermediate quality) and IV (low quality) had <2.5% N and classes I and III had <4% polyphenol and <15% lignin. On the average, yield responses over the control were 60%, 84% and 114% following the addition of ORs, N fertilizers and ORs + N fertilizers, respectively. There was a general increase in yield responses with increasing OR quality and OR-N quantity, both when ORs were added alone or with N fertilizers. Surprisingly, greater OR residual effects were observed with high quality ORs and declined with decreasing OR quality. The greater yield responses with ORs + N fertilizers than either resource alone were mostly due to extra N added and not improved N utilization efficiency because negative interactive effects were, most often, observed when combining ORs with N fertilizers. Additionally, their agronomic N use efficiency was not different from sole added ORs but lower than N fertilizers added alone. Nevertheless, positive interactive effects were observed in sandy soils with low quality ORs whereas agronomic use efficiency was greater when smaller quantities of N were added in all soils. Compared to sole added ORs, yield responses for the combined treatment increased with decreasing OR quality and greater yield increases were observed in sandy (68%) than clayey soils (25%). While ORs and ORs + N fertilizer additions increased SOC by at least 12% compared to the control, N fertilizer additions were not different from control suggesting that ORs are needed to increase SOC. Thus, the addition of ORs will likely improve nutrient storage while crop yields are increased and more so for high quality ORs. Furthermore, interactive effects are seldom occurring, but agronomic N use efficiency of ORs + N fertilizers were greater with low quantities of N added, offering potential for increasing crop productivity.", "keywords": ["Soil nutrients", "0106 biological sciences", "Soil management", "Soil Science", "Plant Science", "fertilidad del suelo", "maize", "Soil fertility", "Soil degradation", "Agronomic n use efficiency", "01 natural sciences", "Soil quality", "ma\u00edz", "Soil", "abonos npk", "npk fertilizers", "Field Scale", "2.

A long-term (11-yr) experiment on a clay loam Orthic Humic Gleysol at Ridgetown, Ontario, Canada was used to evaluate the impact of fertilizer N applications (in-season zero N (\u2212N) compared to (+N) 100 and 80\u00a0kg\u00a0N\u00a0ha-1\u00a0yr.-1 to corn (Zea mays L.) and wheat (Triticum aestivum L.), respectively) on soil attributes.

Data on the C sink capacity of such plantations will provide valuable information for designing improved management strategies for afforestation programmes aimed at mitigating CO2 emissions. The study was carried in the temperate forest of southern Europe, one of the most productive timber production systems in Europe. The study, designed to control most of the variability at regional level, involved a network of 120 paired plots (former pasture land-new plantations of different ages) established to construct three well-replicated chronosequences of the most common tree species in humid temperate systems. The mean rates of C sequestration (biomass and soil) estimated throughout the rotation ranged between 8.7 and 14.6\u00a0Mg\u00a0C\u2009ha\u22121\u00a0year\u22121 (Eucalyptus nitens>Eucalyptus globulus>Pinus radiata), and the contribution of the soil (forest floor plus mineral soil) ranged from 8 to 18% (Eucalyptus nitens>Pinus radiata>Eucalyptus globulus). The humid temperate climate and the sandy loam texture of the soils favoured large losses of SOC from the uppermost mineral soils during the 10\u00a0year after afforestation. The higher loss of SOC in the Pinus radiata soil (26% of initial SOC) than in the Eucalyptus soil (19.45% of initial SOC) was attributed to the lower transfer of organic C to the mineral soil, as a result of the lower litter decomposition rate and the lower belowground litter input from associated vegetation. The rapid development of tree biomass favoured the subsequent C sequestration in biomass and soils. The C sink capacity of forest plantations can be maximized by elongating the rotation length and adopting suitable management strategies for each species. This is especially important in intensive forest plantations in which the high intensity of harvesting may prevent accumulation of SOC in the long term.", "keywords": ["0106 biological sciences", "Eucalyptus", "Pinus radiata", "Tree biomass", "Soil organic matter", "Afforestation", "13.

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.

Although the quantity of soil DOM has been inventoried  across diverse spatio-temporal scales, the underlying mechanisms  accounting for variability in DOM dynamics remain unclear, especially in  upland ecosystems. Here, a gradient of SOM storage across twelve croplands  in northeast China was used to understand links between DOM dynamics,  microbial metabolism, and abiotic conditions. We assessed the composition,  biodegradability and key biodegradable components of DOM. In addition, SOM  and mineral-associated organic matter (MAOM) composition, soil enzyme  activities, oxygen availability, soil texture, iron (Fe), Fe-bound organic  matter and nutrient concentrations were quantified to clarify the drivers  of DOM quality (composition and biodegradability). The proportion of  biodegradable DOM increased exponentially with decreasing initial DOM  concentration due to larger fractions of depolymerized DOM that was rich  in small-molecular phenols and proteinaceous components. Unexpectedly, the  composition of DOM was decoupled from that of SOM or MAOM, but  significantly related to enzymatic properties. These results indicate that  microbial metabolism exhibited a dominant role in DOM generation. As DOM  concentration declined, increased soil oxygen availability regulated DOM  composition and enhanced its biodegradability mainly through mediating  microbial metabolism and Fe oxidation. The oxygen-induced oxidation of  Fe(II) to Fe(III) removed complex DOM compounds with large molecular  weight. Moreover, increased oxygen availability stimulated  oxidase-catalyzed depolymerization of aromatic substances, and promoted  production of protein-like DOM components due to lower enzymatic C/N  acquisition ratio. As global changes in temperature and moisture will have  large impacts on soil oxygen availability, the role of oxygen in  regulating DOM dynamics highlights the importance of integrating soil  oxygen supply with microbial metabolism and Fe redox status to improve  model predictions of soil carbon under climate change.", "keywords": ["2.

However, rigorous empirical evidence from Southeast Asia, particularly in the Cambodian agro-ecosystem, is still scarce. We hypothesized that high and diversified biomass-C inputs in CA might be the first step toward to increase SOC in the topsoil by creating the C flow to support C storage overtime. Thus, the aim of this study was to quantify the short-term (i.e., five year) impacts of soil management and cropping systems on soil organic C (SOC), soil total N (STN), particulate organic C (POC) and mineral-associated organic C (MAOC). There were three distinct experiments comprised of a combination of cover and main crops including rice-, soybean- and cassava-based cropping systems, hereafter designated as RcCS, SbCS and CsCS, respectively. The experimental plots were laid out in a randomized complete block design with three replicates. Soil management treatments included conventional tillage (CT) and no-till (NT) and a selected adjacent area of reference vegetation (RV). Soil sampling was conducted in 2011 and 2013 at seven depths (0\u20135, 5\u201310, 10\u201320, 20\u201340, 40\u201360, 60\u201380 and 80\u2013100\u00a0cm). Soil management and crop sequences significantly affected SOC and STN stocks in all three cropping systems. On average, NT SOC stocks at 0\u20135\u00a0cm depth was greater than those of CT by 10%, 20% and 18% and STN stocks by 8%, 25% and 16% for RcCS, SbCS and CsCS, respectively. SOC levels followed the order RV\u00a0>\u00a0NT\u00a0>\u00a0CT. SOC stocks in the subsoil layers were consistently lower in NT than in CT in all three cropping systems. POC stocks at 0\u20135\u00a0cm depth in NT were on average 22%, 20% and 78% greater than those in CT in RcCS, SbCS and CsCS, respectively. However, significant differences were detected only in RcCS and CsCS. The major POC stocks were found at 0\u201320\u00a0cm depth. NT treatments in SbCS stored 9% greater MAOC stocks at 0\u20135\u00a0cm depth than those in CT, and an increasing trend of NT was observed in RcCS and CsCS. In all three cropping systems, NT systems with diversified crop species significantly increased SOC stocks ranging by 6 to 28% and POC stocks by 56\u2013127% in the surface soils and tended to restore SOC and POC in the subsoil layers after five years. The results leads to accept the hypothesis that short-term CA associated with high biomass-C inputs (particularly bi-annual rotations) promotes SOC recovery in the topsoil layer and creates a potential to increase SOC in the subsoil layers when deep-rooting cover crops are included in crop rotations.", "keywords": ["P33 - Chimie et physique du sol", "cycle du carbone", "sol", "Glycine max", "Manihot esculenta", "F08 - Syst\u00e8mes et modes de culture", "teneur en mati\u00e8re organique", "agro\u00e9cologie", "Oryza sativa", "01 natural sciences", "utilisation des terres", "agriculture alternative", "http://aims.fao.org/aos/agrovoc/c_5388", "http://aims.fao.org/aos/agrovoc/c_33990", "teneur en azote", "http://aims.fao.org/aos/agrovoc/c_4073", "biomasse", "http://aims.fao.org/aos/agrovoc/c_36669", "http://aims.fao.org/aos/agrovoc/c_4579", "savane", "syst\u00e8me de culture", "http://aims.fao.org/aos/agrovoc/c_3301", "http://aims.fao.org/aos/agrovoc/c_8511", "http://aims.fao.org/aos/agrovoc/c_35657", "0105 earth and related environmental sciences", "2.

We found 1) no significant effect of shade trees on coffee production overall; 2) evidence that shade trees do affect flowering and subsequent cherry development, with effects strongly dependent on climate and annual variations in coffee plant physiology; 3) Erythrina shade trees significantly increased soil litter and relative infiltration rate of water in the soil, both linked to soil conservation and decrease in erosion; 4) even in highly fertilized environments, Erythrina trees do fix N which was taken up by adjacent coffee plants. The lack of significant negative effect of shade trees on overall coffee yield and the observation of the provision of other useful services was not unexpected, because of 1) the low density of shade trees in the study site (100\u2013350 trees/ha pruned twice a year on average) and 2) the sensitivity of coffee yields to other interacting effects such as climate, pests and diseases and physiological variations in the plant.

We have considered organic matter addition, no-tillage, crop rotation and organic agriculture as 'promising practices'; no organic matter input, conventional tillage, monoculture and conventional farming were taken as the respective references or 'standard practice' (baseline). Relative effects were analysed through indicator response ratio (RR) under each paired practice. For this we considered data of 30 long-term experiments collected from 13 case study sites in Europe and China as collated in the framework of the EU-China funded iSQAPER project. These were complemented with data from 42 long-term experiments across China and 402 observations of long-term trials published in the literature. Out of these, we only considered experiments covering at least five years. The results show that OM addition favourably affected all the indicators under consideration. The most favourable effect was reported on earthworm numbers, followed by yield, SOM content and soil aggregate stability. For pH, effects depended on soil type; OM input favourably affected the pH of acidic soils, whereas no clear trend was observed under NT. NT generally led to increased aggregate stability and greater SOM content in upper soil horizons. However, the magnitude of the relative effects varied, e.g. with soil texture. No-tillage practices enhanced earthworm populations, but not where herbicides or pesticides were applied to combat weeds and pests. Overall, in this review, yield slightly decreased under NT. Crop rotation had a positive effect on SOM content and yield; rotation with ley very positively influenced earthworms' numbers. Overall, crop rotation had little impact on soil pH and aggregate stability \u2212 depending on the type of intercrop; alternatively, rotation of arable crops only resulted in adverse effects. A clear positive trend was observed for earthworm abundance under organic agriculture. Further, organic agriculture generally resulted in increased aggregate stability and greater SOM content.

Since independence in the 1960s, grazing lands have been opened to all without specific guidance, and the vulnerability of the pastures to degradation has increased. Rotational grazing is postulated as a possible solution to provide higher pasture productivity, higher animal loads per unit land, and perhaps improved soil carbon storage. The objective of this study was to conduct a simulation-based assessment of the impact of rotational grazing management on pasture biomass production, grazing efficiency, animal grazing requirement satisfaction, and soil carbon storage in the Madiama Commune, Mali. The results showed that grazing intensity is the primary factor influencing the productivity of annual pastures and their capacity to provide for animal grazing requirements. Rotating the animals in paddocks is a positive practice for pasture protection that showed advantage as the grazing pressure increased. Increasing the size of the reserve biomass not available for grazing, which triggers the decision of taking the animals off the field, provided better pasture protection but reduced animal grazing requirements satisfaction. In terms of soil carbon storage, all management scenarios led to reduction of soil carbon at the end of the 50-year simulation periods, ranging between 4% and 5% of the initial storage. The differences in reduction as a function of grazing intensity were of no practical significance in these soils with very low organic matter content, mostly resistant to decomposition.", "keywords": ["Carbon sequestration", "Livestock management", "2.

Additionally, markets outside of the Protocol are developing for soil C sequestration.  In theory, C markets present win-win opportunities for buyers and sellers of C stocks. In practice, however, C markets are very complex. They presuppose the existence and integration of technical capacity to enhance C storage in production systems, the capacity for resource users to adopt and maintain land resource practices that sequester C, the ability for dealers or brokers to monitor C stocks at a landscape level, the institutional capacity to aggregate C credits, the financial mechanisms for incentive payments to reach farmers, and transparent and accountable governance structures that can ensure equitable distribution of benefits. Hence, while C payments may contribute to increasing rural incomes and promoting productivity enhancement practices, they may also expose resource users to additional social tensions and institutional risks.", "keywords": ["Carbon sequestration", "Poverty reduction", "Clean Development Mechanism (CDM)", "01 natural sciences", "12.

In Madagascar, cropping systems based on direct seeding with permanent vegetation cover provide a new means for sustainable agriculture to protect the environment and make the most of natural resources. This study assessed the effects of different direct seeding mulch-based cropping systems on soil microbial biomass and activities. The soil was andic Dystrustept. Samples of the soil were taken from 0 to 5\u00a0cm soil layer of three direct seeding mulch-based cropping systems (DMC using crop residues and living mulches). The samples were compared with samples from conventionally tilled plots (CT) and natural fallows (NF). The field experiments were carried out over a 12-year-period and two types of amendment were applied once a year at sowing, farmyard manure (FYM) and farmyard manure combined with an NPK chemical fertilizer. The C and N content, microbial basal respiration and biomass and \u03b2-glucosidase, urease and acid phosphatase activities were determined. The results showed that there was no interaction between soil management strategies and the use of fertilizer. Furthermore, the fertilizer did not affect the soil C and N content or the acid phosphatase and urease activities. Farmyard manure with added NPK had a significantly greater effect than farmyard manure on its own, increasing the microbial biomass, soil respiration and \u03b2-glucosidase activity up to 26%, 52% and 20%, respectively but there was no significant difference between natural fallows and direct seeding mulch-based cropping systems. However, conventional tillage showed a significantly lower soil microbial biomass, C content, microbial respiration and urease activity than natural fallows. The results for direct seeding mulch-based systems varied according to the microbial activities measured. However, soil \u03b2-glucosidase and acid phosphatase activities were significantly higher for the direct seeding mulch-based systems using crop residues than for the direct seeding mulch-based systems using living mulches. Direct seeding mulch-based systems with Desmodium uncinatum living mulch had significantly lower microbial biomass and respiration than the other direct seeding mulch-based systems. There was less evidence of change in the soil between natural fallow and direct seeding mulch-based systems but a higher build-up of some microbial properties was obtained for direct seeding mulch-based systems soil than in conventionally tilled soils and natural fallow.", "keywords": ["crop residues", "Glycine max", "http://aims.fao.org/aos/agrovoc/c_7170", "living mulch", "microbial activity", "Zea mays", "630", "http://aims.fao.org/aos/agrovoc/c_36167", "micro-organisme du sol", "http://aims.fao.org/aos/agrovoc/c_33553", "http://aims.fao.org/aos/agrovoc/c_3301", "http://aims.fao.org/aos/agrovoc/c_4510", "http://aims.fao.org/aos/agrovoc/c_16118", "http://aims.fao.org/aos/agrovoc/c_35657", "F07 - Fa\u00e7ons culturales", "2.

At the end of 13 years, soil samples were taken to a depth of 100 cm, and analysed for bulk density, chemical composition and 13 C natural abundance. Under a continuous sequence of wheat (winter) and soybean (summer) the stock of soil organic C to 100 cm depth under ZT (168 Mg ha \u22121 ) was not significantly different (LSD at P = 0.05 of 11 Mg ha \u22121 ) to that under CT (168 Mg ha \u22121 ). However, in the rotations with vetch planted as a winter green-manure crop (R2 and R3), soil C stocks were approximately 17 Mg ha \u22121 higher under ZT than under CT. Between 46 and 68% of this difference occurred at 30\u201385 cm depth. The 13 C abundance data indicated that under ZT the decomposition of the original native SOM was not affected by the different composition of crops in the different rotations, but under CT the rotations R2 and R3, which included vetch and maize, stimulated the decay of the original native SOM compared to the continuous wheat/soybean sequence (R1). It appears that the contribution of N2 fixation by the leguminous green manure (vetch) in the cropping system was the principal factor responsible for the observed C accumulation in the soil under ZT, and that most accumulated C was derived from crop roots. \u00a9 2003 Elsevier B.V.

We evaluated the role of two representative Cerrado Oxisols (350 and 650\u00a0g clay\u00a0kg\u22121) as sources or sinks of atmospheric C when managed under three tillage systems (conventional tillage (CT), reduced tillage (RT), and no-till (NT)) in 8- and 5-year long-term experiments. A literature review was also carried out and the mean C sequestration rates in no-till soils of tropical and subtropical regions of Brazil were calculated and compared with values for soils from temperate regions of the world. The original C stocks in 0\u201320\u00a0cm layer of soils under native Cerrado were higher in the clayey (54.0\u00a0Mg\u00a0ha\u22121) than in the sandy clay loam soil (35.4\u00a0Mg\u00a0ha\u22121), suggesting a higher physical stability of organic matter associated with variable clay minerals in the clayey Oxisol. The original C stocks of the native Cerrado soils appear not to have decreased after 23 years of conventional tillage in the sandy clay loam Oxisol, except when the soil had been subjected to erosion (15% loss of C), or after 25 years in the clayey Oxisol. Compared to conventionally tilled soil, the C stocks in no-till sandy clay loam Oxisol increased by 2.4\u00a0Mg\u00a0ha\u22121 (C sequestration rate\u00a0=\u00a00.30\u00a0Mg\u00a0ha\u22121\u00a0year\u22121) and in the clayey Oxisol by 3.0\u00a0Mg\u00a0ha\u22121 (C sequestration rate\u00a0=\u00a00.60\u00a0Mg\u00a0ha\u22121\u00a0year\u22121). The mean rate of C sequestration in the no-till Brazilian tropical soils was estimated to be 0.35\u00a0Mg\u00a0ha\u22121\u00a0year\u22121, similar to the 0.34\u00a0Mg\u00a0ha\u22121\u00a0year\u22121 reported for soils from temperate regions but lower than the 0.48\u00a0Mg\u00a0ha\u22121\u00a0year\u22121 estimated for southern Brazilian subtropical soils. Considering the large area (about 70 million hectares) of the Cerrado which is currently used and potentially available for cropland, the adoption of no-till systems could turn the Cerrado soils into a significant sink for atmospheric C and contribute to the mitigation of global climate change.", "keywords": ["Carbon sequestration", "2.

The objective of this report is to assess the feasibility of using SOC-SR as an index for estimating SOC sequestration in NT soils. The effect of a plow tillage (PT) and NT chronosequence on the SR of SOM pools was assessed in an Oxisol in Southern Brazil (50\u00b023\u2032W and 24\u00b036\u2032S). The chronosequence consisted of six sites: (i) native field (NF); (ii) PT of the native field (PNF-1) involving conversion of natural vegetation to cropland; (iii) NT for 10 years (NT-10); (iv) NT for 20 years (NT-20); (v) NT for 22 years (NT-22); (vi) conventional tillage for 22 years (CT-22). Soil samples were collected from four depths (0\u20135\u00a0cm; 5\u201310\u00a0cm; 10\u201320\u00a0cm; 20\u201340\u00a0cm layer) and soil parameters comprised by SOM pools [i.e., C, N, S, particulate organic C (POC), particulate N (PN), stable C (SC) and stable N (SN), microbial biomass C (MBC) and microbial biomass N (MBN), basal respiration (BR), dissolved organic C (DOC), total polysaccharides (TP) and labile polysaccharides (LP)] were measured. In undisturbed NF soil, the SR of all parameters increased with increase in soil depth. In contrast, the SR decreased in PT, and the SOM was uniformly distributed in the soil profile. All NT treatments restored the SR, and were characterized with higher values of all measured parameters compared to NF. The SR for SOC ranged from 1.12 to 1.51 for CT-22 compared with 1.64\u20132.61 SR for NT surface and sub-soil layers, respectively. The SR for POC and PN were higher than those for stable C and N. However, SR for the biological pools (e.g., MBC, MBN and BR) were the highest and strongly correlated with the rate of SOC sequestration. An increase in SR of SOC was also positively correlated with the rate and amount of SOC sequestered. Regression analyses indicated a strong correlation between SR of SOC and all parameters monitored in this study. The data showed that the SR of SOC is an efficient indicator of C sequestration in long-term NT management.", "keywords": ["Carbon sequestration", "2.

Therefore, the impact of soil water and integrated fertilization after eight years on prokaryotic microbial communities in different compartments of root zone and their association with wheat nitrogen (N) absorption and yield were investigated. The results showed that compared with fertilization treatments (F), water regimes (W) more drastically modulated the prokaryotic microbial community structure and diversity in bulk soil, rhizosphere and endosphere. The increase of irrigation improved the prokaryotic diversity in the rhizosphere and endosphere while decreased the diversity in the bulk soil. Application of organic fertilizers significantly improved soil organic matter (SOM) and nutrient contents, increased rhizosphere and endophytic prokaryotic microbial diversity, and elevated the relative abundance of aerobic ammonia oxidation and nitrification-related functional microorganisms in rhizosphere and endosphere. Increasing irrigation elevated the relative abundance of functional microorganisms related to aerobic ammonia oxidation and nitrification in the rhizosphere and endosphere. Soil water content (SWC) and NH4+-N as well as NO3\u2212-N were key predictors of prokaryotic microbial community composition under W and F treatments, respectively. Appropriate application of irrigation and organic fertilizers increased the relative abundance of some beneficial bacteria such as Flavobacterium. Water and fertilization treatments regulated the prokaryotic microbial communities of bulk soil, rhizosphere and endosphere by altering SWC and SOM, and provided evidence for the modulation of prokaryotic microorganisms to promote nitrogen uptake and wheat yield under long-term irrigation and fertilization. Conclusively, the addition of organic manure (50 %) with inorganic fertilizers (50 %) and reduced amount of irrigation (pre-sowing and jointing-period irrigation) decreased the application amount of chemical fertilizers and water, while increased SOM and nutrient content, improved prokaryotic diversity, and changed prokaryotic microbial community structure in the wheat root zone, resulting in enhanced nutrient uptake and wheat yield.", "keywords": ["0106 biological sciences", "Yield", "Microorganism", "Microbial population biology", "Nitrogen", "Soil Science", "Organic chemistry", "Plant Science", "01 natural sciences", "Environmental science", "Agricultural and Biological Sciences", "Soil", "Symbiotic Nitrogen Fixation in Legumes", "Soil water", "Genetics", "Fertilizers", "Biology", "Irrigation", "Soil Microbiology", "Triticum", "2.

The objectives of our study were: (1) to quantify the effects of contrasting organic residue (OR) retention methods on tree growth and soil nutrient pools over a full  Eucalyptus  rotation and (2) to assess the potential of soil analyses to predict yields of fast-growing plantations established on tropical sandy soils. An experiment was set up in the Congo at the harvesting of the first rotation after afforestation of a native herbaceous savanna. Six treatments were set up in 0.26\u00a0ha plots and replicated in 4 blocks, with OR mass at planting ranging from 0 to 46.5\u00a0Mg\u00a0ha \u22121 . Tree growth over the whole rotation was highly dependent on OR management at planting. Over-bark trunk volume 7 years after planting ranged from 96\u00a0m 3 \u00a0ha \u22121  in the treatment with forest floor and harvest residue removal at planting to 164\u00a0m 3 \u00a0ha \u22121  in the treatment with the largest amount of OR. A comparison of nutrient stocks within the ecosystem at planting and at the end of the rotation suggested that nutrient contents in OR were largely involved in the different response observed between treatments. OR management treatments did not significantly modify most of the nutrient concentrations in the upper layers of the mineral soil. Conventional soil analyses performed before planting and at ages 1 and 3 years were unable to detect differences between treatments despite large differences in tree growth. In contrast, linear regressions between stand aboveground biomass at harvesting and OR mass at planting (independent variable) showed that OR mass was an excellent predictor of stand yield ( R  2 \u00a0=\u00a00.99). A large share of soil fertility comes from organic material above the mineral soil in highly weathered sandy soils and OR mass at planting might be used in conjunction with soil analyses to assess the potential of these soils to support forest plantations.", "keywords": ["0106 biological sciences", "570", "http://aims.fao.org/aos/agrovoc/c_7170", "[SDV]Life Sciences [q-bio]", "rendement des cultures", "Slash", "F62 - Physiologie v\u00e9g\u00e9tale - Croissance et d\u00e9veloppement", "for\u00eat tropicale", "01 natural sciences", "630", "http://aims.fao.org/aos/agrovoc/c_10176", "http://aims.fao.org/aos/agrovoc/c_24904", "sol tropical", "http://aims.fao.org/aos/agrovoc/c_16118", "http://aims.fao.org/aos/agrovoc/c_5387", "2.

This study evaluated bulk soil C and nitrogen (N) contents and C and N dynamics in three soil organic matter (SOM) fractions separated by density. The study was based on three tillage systems on farmer managed experiments (conventional tillage (CT), ripping (RP), direct seeding (DS)) and adjacent natural forest (NF) in Haplic Arenosols (sandy) and Rhodic Ferralsols (clayey) of Zimbabwe. Carbon stocks were significantly larger in forests than tillage systems, being significantly lower in sandy soils (15 and 14\u00a0Mg\u00a0C\u00a0ha\u2212\u00a01) than clayey soils (23 and 21\u00a0Mg\u00a0C\u00a0ha\u2212\u00a01) at 0\u201310 and 10\u201330\u00a0cm respectively. Nitrogen content followed the same trend. At the 0\u201310\u00a0cm depth, SOC stocks increased under CT, RP and DS by 0.10, 0.24, 0.36\u00a0Mg\u00a0ha\u2212\u00a01\u00a0yr\u2212\u00a01 and 0.76, 0.54, 0.10\u00a0Mg\u00a0ha\u2212\u00a01\u00a0yr\u2212\u00a01 on sandy and clayey soils respectively over a four year period while N stocks decreased by 0.55, 0.40, 0.56\u00a0Mg\u00a0ha\u2212\u00a01 and 0.63, 0.65, 0.55\u00a0Mg\u00a0ha\u2212\u00a01 respectively.

Tillage systems on sandy soils had the smallest average free light fraction (fLF) and occluded light fraction (oLF) C stocks (25.3\u00a0\u00b1\u00a01.3 g m\u2212\u00a02 and 7.3\u00a0\u00b1\u00a01.2\u00a0g\u00a0m\u2212\u00a02) at 0\u201330\u00a0cm when compared with corresponding NF (58.4\u00a0\u00b1\u00a04 g\u00a0m2 and 18.5\u00a0\u00b1\u00a01.0\u00a0g\u00a0m\u2212\u00a02).

Results suggest that oLF and MaHF C and N are better protected under DS and RP where they are less vulnerable to mineralisation while fLF contributes more in CT. Thus, DS and RP can be important in maintaining and improving soil quality although their practicability can be hampered by unsupportive institutional frameworks. Under prevailing climatic and management conditions, improvement of residue retention could be a major factor that can distinguish the potential of different management practices for C sequestration. The exploitation of the benefits of RP or DS and the corresponding sustainability of systems need support for surface cover retention which should also be extended to conventional tillage.", "keywords": ["2.

The objective of this study is to assess the long-term cumulative effects of change in land-use type on some soil properties in the continental lowland ecosystems of Western Serbia. Three adjacent land-use types (deciduous forest, natural grassland and arable soils that have been converted from forests for more than 100\u00a0years) were chosen for the study. Disturbed and undisturbed soil samples were collected from nine sites at each of the three different land-use types from the depths of 0\u201310, 10\u201320 and 20\u201330\u00a0cm in noncarbonated Fluvisol. Conversion of forest to grassland and arable soil has led to significant decrease in total porosity (TP), infiltration rate (IR) and soil organic matter (SOM). The bulk density (BD) was lower in forest compared to the adjacent grassland and arable (ex-forest) soils. In addition, microaggregate stability, determined by the clay dispersion ratio (CDR) and aggregated silt and clay (ASC) indices, was significantly higher in forest than in grassland and arable soil. In conclusion, the results of this study indicate that removal of permanent vegetation in the conversion process from forest and grassland areas to cultivated land may lead to loss of soil productivity and serious soil degradation. Obviously, there is a need for greater attention to developing sustainable land use practices in management of these ecosystems to prevent further degradation of soils in the region.", "keywords": ["2.

However, most present knowledge on the impact of agroforestry systems on soil organic carbon (SOC) storage comes from tropical systems. This study was conducted in southern France, in an 18-year-old agroforestry plot, where hybrid walnuts ( Juglans regia  \u00d7  nigra  L.) are intercropped with durum wheat ( Triticum turgidum  L. subsp.  durum ), and in an adjacent agricultural control plot, where durum wheat is the sole crop. We quantified SOC stocks to 2.0\u00a0m depth and their spatial variability in relation to the distance to the trees and to the tree rows. The distribution of additional SOC storage in different soil particle-size fractions was also characterized. SOC accumulation rates between the agroforestry and the agricultural plots were 248\u00a0\u00b1\u00a031\u00a0kg\u00a0C\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01  for an equivalent soil mass (ESM) of 4000\u00a0Mg\u00a0ha \u2212\u00a01  (to 26\u201329\u00a0cm depth) and 350\u00a0\u00b1\u00a041\u00a0kg\u00a0C\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01  for an ESM of 15,700\u00a0Mg\u00a0ha \u2212\u00a01  (to 93\u201398\u00a0cm depth). SOC stocks were higher in the tree rows where herbaceous vegetation grew and where the soil was not tilled, but no effect of the distance to the trees (0 to 10\u00a0m) on SOC stocks was observed. Most of the additional SOC storage was found in coarse organic fractions (50\u2013200 and 200\u20132000\u00a0\u03bcm), which may be rather labile fractions. All together our study demonstrated the potential of alley cropping agroforestry systems under Mediterranean conditions to store SOC, and questioned the stability of this storage.", "keywords": ["[SDV.SA]Life Sciences [q-bio]/Agricultural sciences", "http://aims.fao.org/aos/agrovoc/c_28568", "Juglans regia", "F08 - Syst\u00e8mes et modes de culture", "culture associ\u00e9e", "Triticum turgidum", "630", "spectroscopie infrarouge", "zone m\u00e9diterran\u00e9enne", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "http://aims.fao.org/aos/agrovoc/c_35657", "agroforesterie", "2.
