A long-term experiment (1972\uffe2\uff80\uff931992) run in Benin consisted of two phases: a depletion phase (1972\uffe2\uff80\uff931980) with varying levels of mineral and organic fertilisation, and a regeneration phase (1981\uffe2\uff80\uff931992) where all plots received full fertilisation and organic matter additions. Soils were sampled at 0\uffe2\uff80\uff9320\uffc2\uffa0cm depth in 1973, 1974, 1982, and 1989 to assess fertility changes. Mineral fertilisation (N, P, K) and plant biomass management (crop residue retention and biomass additions) significantly influenced seed cotton and maize grain yields during the depletion phase. Soil organic carbon declined consistently in all treatments during depletion but remained stable during regeneration. The long-term effect was evident only in seed cotton yield during depletion. In contrast, due to high variability, maize grain yield showed no consistent trend. The combined use of organic resources and mineral fertilisers helped maintain crop productivity but led to declining soil chemical properties in this Ferralsol. The analysis of this outdated yet unpublished dataset shed light on how long-term soil depletion effects persist over time, even when soil fertility management is restored, indicating a sort of \uffe2\uff80\uff98soil memory\uffe2\uff80\uff99. The persistence of these effect suggests that regenerative interventions must begin before critical thresholds of degradation are crossed. Future research should focus on alternative measures to restore/maintain soil fertility not evaluated in this experiment, such as conservation tillage or legume integration, to provide long-term benefits for smallholder farmers facing soil fertility challenges.</p", "keywords": ["Crop residues", "diversification", "propri\u00e9t\u00e9 physicochimique du sol", "IMPACT", "http://aims.fao.org/aos/agrovoc/c_7170", "rendement des cultures", "Cotton-maize yields", "Nutrient cycling", "http://aims.fao.org/aos/agrovoc/c_875", "fertilisation", "CARBON", "CROP PRODUCTIVITY", "http://aims.fao.org/aos/agrovoc/c_10176", "Long-term experiment", "mauvaise herbe", "http://aims.fao.org/aos/agrovoc/c_2018", "http://aims.fao.org/aos/agrovoc/c_7165", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "COMPOST", "pratique culturale", "http://aims.fao.org/aos/agrovoc/c_8511", "http://aims.fao.org/aos/agrovoc/c_10795", "http://aims.fao.org/aos/agrovoc/c_7168", "http://aims.fao.org/aos/agrovoc/c_35657", "Gossypium", "Soil organic carbon", "MEMORY", "http://aims.fao.org/aos/agrovoc/c_7182", "Soil's memory", "non-travail du sol", "http://aims.fao.org/aos/agrovoc/c_8fc04948", "http://aims.fao.org/aos/agrovoc/c_331583", "STATE", "ORGANIC-MATTER", "fertilit\u00e9 du sol", "s\u00e9questration du carbone", "http://aims.fao.org/aos/agrovoc/c_8347", "YIELD", "d\u00e9gradation du sol", "conservation des sols", "MINERAL FERTILIZER", "http://aims.fao.org/aos/agrovoc/c_3335", "gestion int\u00e9gr\u00e9e de la fertilit\u00e9 des sols", "http://aims.fao.org/aos/agrovoc/c_2344", "mati\u00e8re organique du sol"]}, "links": [{"href": "https://doi.org/10.1007/s10705-025-10429-1"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Nutrient%20Cycling%20in%20Agroecosystems", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1007/s10705-025-10429-1", "name": "item", "description": "10.1007/s10705-025-10429-1", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1007/s10705-025-10429-1"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-08-20T00:00:00Z"}}, {"id": "0b644920-ff5e-4aac-a124-8b478bda606c", "type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[2.75, 49.45], [2.75, 50.85], [6.5, 50.85], [6.5, 49.45], [2.75, 49.45]]]}, "properties": {"themes": [{"concepts": [{"id": "biota"}], "scheme": "https://standards.iso.org/iso/19139/resources/gmxCodelists.xml#MD_TopicCategoryCode"}, {"concepts": [{"id": "Nature et environnement"}, {"id": "Sol et sous-sol"}], "scheme": "https://metawal.wallonie.be/thesaurus/theme-geoportail-wallon"}, {"concepts": [{"id": "biologie"}, {"id": "dynamique naturelle"}, {"id": "sol"}], "scheme": "http://geonetwork-opensource.org/gemet-theme"}, {"concepts": [{"id": "structure du sol"}, {"id": "cycle du carbone"}, {"id": "for\u00eat"}, {"id": "organisme du sol"}, {"id": "mati\u00e8re organique"}, {"id": "sol"}, {"id": "chimie des sols"}, {"id": "biologie du sol"}, {"id": "d\u00e9terioration du sol"}, {"id": "d\u00e9gradation du sol"}, {"id": "prairie"}, {"id": "carbone organique"}, {"id": "carbone organique total"}, {"id": "carbone"}, {"id": "fertilit\u00e9 du sol"}], "scheme": "http://geonetwork-opensource.org/gemet"}, {"concepts": [{"id": "Reporting INSPIRE"}, {"id": "Extraction_DIG"}, {"id": "WalOnMap"}, {"id": "BDInfraSIG"}, {"id": "Open Data"}, {"id": "PanierTelechargementGeoportailNO"}], "scheme": "https://metawal.wallonie.be/thesaurus/infrasig"}, {"concepts": [{"id": "Sols"}], "scheme": "http://inspire.ec.europa.eu/theme"}, {"concepts": [{"id": "R\u00e9gional"}], "scheme": "http://inspire.ec.europa.eu/metadata-codelist/SpatialScope"}, {"concepts": [{"id": "Observation de la terre et environnement"}], "scheme": "http://data.europa.eu/bna/asd487ae75"}, {"concepts": [{"id": "2023/138"}], "scheme": "http://data.europa.eu/r5r/applicableLegislation"}], "rights": "Conditions d'acc\u00e8s et d'utilisation sp\u00e9cifiques", "updated": "2023-06-20T12:48:33.221Z", "type": "Dataset", "created": "2016-12-30", "language": "fre", "title": "CARBIOSOL - Uncertainties of Total Organic Carbon Contents - period 2004-2014", "description": "Cette couche de donn\u00e9es reprend les incertitudes des teneurs en COT dans les sols sous cultures et prairies permanentes du territoire wallon entre la p\u00e9riode 2004-2014.\n\nCette couche de donn\u00e9es reprend les incertitudes (ici coefficient de variation - CV) de mod\u00e9lisation pour les teneurs en COT pr\u00e9dites dans les sols sous cultures et prairies du territoire wallon pour la p\u00e9riode 2004-2014.

For this reason, we have carried out a thirty-two-year-old long-term trial in Kabete, Kenya. These soils were treated with organic (maize stover (MS) at 10 t ha\u22121, farmyard manure (FYM) at 10 t ha\u22121) and inorganic fertilizers 120 kg N, 52.8 kg P (N2P2), N2P2 + MS, N2P2 + FYM, a control, and a fallow for over 30 years. We examined 16S rRNA gene and 28S rRNA gene fingerprints of bacterial and fungal diversity by PCR amplification and denaturing gradient gel electrophoresis separation, respectively. The PCR bacterial community structure and diversity were negatively affected by N2P2 and were more closely related to the bacterial structure in the soils without any addition (control) than that of soils with a combination of inorganic and organic or inorganic fertilizers alone. The effect on fungal diversity by N2P2 was different than the effect on bacterial diversity since the fungal diversity was similar to that of the N2P2 + FYM and N2P2 + MS-treated. However, soils treated with organic inputs clustered away from soils amended with inorganic inputs. Organic inputs had a positive effect on both bacterial and fungal diversity with or without chemical fertilizers.

However, the precise relationships between soil properties and microbial diversity are poorly known. Here, we study the effect of agricultural management on soil microbial diversity and C turnover in tropical grassland of north-eastern Laos. Three years after native grassland conversion into agricultural land, we compared soils from five land use management systems: one till versus two no-till rotational cropping systems, one no-till improved pasture and the natural grassland. Soils were incubated in microcosms during 64 days at optimum temperature and humidity. Bacterial and fungal diversity were evaluated by metagenomic 454-pyrosequencing of 16S and 18SrRNA genes, respectively. Changes in soil respiration patterns were evaluated by monitoring 12C- and 13C-CO2 release after soil amendment with 13C-labelled wheat residues. Results show that residue mineralization increased with bacterial richness and diversity in the tilled treatment 7 days after soil amendment. Native soil organic C mineralization and priming effect increased with fungal richness and diversity in improved pasture and natural grassland. No-till cropping systems represented intermediate situations between tillage and pasture systems.

Our aim was to test this hypothesis for intercropped durum wheat and faba bean along a P-fertilizer gradient. A field experiment was conducted in a long-term P-fertilizer trial with three rates of P-fertilization (No, Low and High P). Microbial biomass was assessed by chloroform fumigation-extraction. Quantitative PCR was applied to evaluate the abundance of relevant microbial groups. Phosphorus availability and microbial biomass systematically increased in the rhizosphere compared to bulk soil. P-fertilization resulted in higher abundance of targeted bacterial phyla, whole bacterial and fungal communities, and depressed mycorrhizal colonization of durum wheat, but not faba bean. Microbial biomass carbon significantly increased in the rhizosphere only in P-fertilized treatments, pointing to P limitation of microbial communities. Intercropping yielded a significant effect on rhizosphere microbial properties only at High P. Microbial biomass P increased in the rhizosphere of intercropped faba bean only at No P level, and was thus the sole finding supporting the stress-gradient hypothesis. P-fertilization was the main driver of microbial communities in this field trial, and P-fertilizer application modulated the species-specific effect in the intercrop.

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.

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.

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.

Long term fallow is no longer possible in densely populated tropical areas, but legume cover crops can help maintain soil fertility. Our work aimed to study changes in soil carbon in a sandy loam Ultisol in Benin, which involved a 12\uffe2\uff80\uff90year experiment on three maize cropping systems under manual tillage: traditional no\uffe2\uff80\uff90input cultivation (T), mineral fertilized cultivation (NPK), and association with Mucuna pruriens (M). The origin of soil carbon was also determined through the natural abundance of soil and biomass 13C.

After 12 years of experimentation, carbon originating from maize in litter\uffe2\uff80\uff90plus\uffe2\uff80\uff90soil (0\uffe2\uff80\uff9340 cm) represented less than 4% of both total carbon and overall maize residue carbon. In contrast, carbon originating from mucuna in litter\uffe2\uff80\uff90plus\uffe2\uff80\uff90soil represented more than 50% of both total carbon and overall mucuna residue carbon in M, possibly due to accelerated mineralization of native soil carbon (priming effect) and slow mulch decomposition. Carbon originating from weeds in litter\uffe2\uff80\uff90plus\uffe2\uff80\uff90soil represented c. 10% of both total carbon and overall weed residue carbon in T and NPK.

Integrating soil erosion and water sediment data with local perceptions of land degradation in an upland village of northern Laos, this study tests the validity of the official environmental discourse.

A long-term experiment (1972\uffe2\uff80\uff931992) run in Benin consisted of two phases: a depletion phase (1972\uffe2\uff80\uff931980) with varying levels of mineral and organic fertilisation, and a regeneration phase (1981\uffe2\uff80\uff931992) where all plots received full fertilisation and organic matter additions. Soils were sampled at 0\uffe2\uff80\uff9320\uffc2\uffa0cm depth in 1973, 1974, 1982, and 1989 to assess fertility changes. Mineral fertilisation (N, P, K) and plant biomass management (crop residue retention and biomass additions) significantly influenced seed cotton and maize grain yields during the depletion phase. Soil organic carbon declined consistently in all treatments during depletion but remained stable during regeneration. The long-term effect was evident only in seed cotton yield during depletion. In contrast, due to high variability, maize grain yield showed no consistent trend. The combined use of organic resources and mineral fertilisers helped maintain crop productivity but led to declining soil chemical properties in this Ferralsol. The analysis of this outdated yet unpublished dataset shed light on how long-term soil depletion effects persist over time, even when soil fertility management is restored, indicating a sort of \uffe2\uff80\uff98soil memory\uffe2\uff80\uff99. The persistence of these effect suggests that regenerative interventions must begin before critical thresholds of degradation are crossed. Future research should focus on alternative measures to restore/maintain soil fertility not evaluated in this experiment, such as conservation tillage or legume integration, to provide long-term benefits for smallholder farmers facing soil fertility challenges.</p", "keywords": ["Crop residues", "propri\u00e9t\u00e9 physicochimique du sol", "IMPACT", "rendement des cultures", "Cotton-maize yields", "http://aims.fao.org/aos/agrovoc/c_875", "fertilisation", "CARBON", "Long-term experiment", "mauvaise herbe", "http://aims.fao.org/aos/agrovoc/c_2018", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "COMPOST", "http://aims.fao.org/aos/agrovoc/c_8511", "http://aims.fao.org/aos/agrovoc/c_10795", "http://aims.fao.org/aos/agrovoc/c_35657", "Cotton\u2013maize yields", "http://aims.fao.org/aos/agrovoc/c_7182", "Soil's memory", "non-travail du sol", "http://aims.fao.org/aos/agrovoc/c_8fc04948", "STATE", "[SDV] Life Sciences [q-bio]", "http://aims.fao.org/aos/agrovoc/c_8347", "ORGANIC-MATTER", "s\u00e9questration du carbone", "fertilit\u00e9 du sol", "Soil\u2019s memory", "http://aims.fao.org/aos/agrovoc/c_3335", "gestion int\u00e9gr\u00e9e de la fertilit\u00e9 des sols", "mati\u00e8re organique du sol", "diversification", "http://aims.fao.org/aos/agrovoc/c_7170", "Nutrient cycling", "CROP PRODUCTIVITY", "http://aims.fao.org/aos/agrovoc/c_10176", "B\u00e9nin", "http://aims.fao.org/aos/agrovoc/c_7165", "pratique culturale", "http://aims.fao.org/aos/agrovoc/c_7168", "Longterm experiment", "Gossypium", "Soil organic carbon", "MEMORY", "http://aims.fao.org/aos/agrovoc/c_331583", "YIELD", "d\u00e9gradation du sol", "conservation des sols", "MINERAL FERTILIZER", "http://aims.fao.org/aos/agrovoc/c_2344"]}, "links": [{"href": "https://doi.org/11370/a5fba259-dd61-43ac-8b8a-86b2d5fd6cef"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Nutrient%20Cycling%20in%20Agroecosystems", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "11370/a5fba259-dd61-43ac-8b8a-86b2d5fd6cef", "name": "item", "description": "11370/a5fba259-dd61-43ac-8b8a-86b2d5fd6cef", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/11370/a5fba259-dd61-43ac-8b8a-86b2d5fd6cef"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-08-20T00:00:00Z"}}, {"id": "530b194d-5f66-482f-b536-22db24249f91", "type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[2.75, 49.45], [2.75, 50.85], [6.5, 50.85], [6.5, 49.45], [2.75, 49.45]]]}, "properties": {"themes": [{"concepts": [{"id": "biota"}], "scheme": "https://standards.iso.org/iso/19139/resources/gmxCodelists.xml#MD_TopicCategoryCode"}, {"concepts": [{"id": "Nature et environnement"}, {"id": "Sol et sous-sol"}], "scheme": "https://metawal.wallonie.be/thesaurus/theme-geoportail-wallon"}, {"concepts": [{"id": "Sols"}], "scheme": "http://inspire.ec.europa.eu/theme"}, {"concepts": [{"id": "dynamique naturelle"}, {"id": "biologie"}, {"id": "sol"}], "scheme": "http://geonetwork-opensource.org/gemet-theme"}, {"concepts": [{"id": "biologie du sol"}, {"id": "for\u00eat"}, {"id": "cycle du carbone"}, {"id": "d\u00e9terioration du sol"}, {"id": "organisme du sol"}, {"id": "structure du sol"}, {"id": "carbone organique"}, {"id": "d\u00e9gradation du sol"}, {"id": "fertilit\u00e9 du sol"}, {"id": "carbone"}, {"id": "mati\u00e8re organique"}, {"id": "chimie des sols"}, {"id": "sol"}, {"id": "prairie"}, {"id": "carbone organique total"}], "scheme": "http://geonetwork-opensource.org/gemet"}, {"concepts": [{"id": "BDInfraSIG"}, {"id": "Extraction_DIG"}, {"id": "Reporting INSPIRE"}, {"id": "WalOnMap"}, {"id": "Open Data"}, {"id": "PanierTelechargementGeoportailNO"}], "scheme": "https://metawal.wallonie.be/thesaurus/infrasig"}, {"concepts": [{"id": "R\u00e9gional"}], "scheme": "http://inspire.ec.europa.eu/metadata-codelist/SpatialScope"}, {"concepts": [{"id": "Observation de la terre et environnement"}], "scheme": "http://data.europa.eu/bna/asd487ae75"}, {"concepts": [{"id": "2023/138"}], "scheme": "http://data.europa.eu/r5r/applicableLegislation"}], "rights": "Conditions d'acc\u00e8s et d'utilisation sp\u00e9cifiques", "updated": "2023-06-21T06:18:06.216Z", "type": "Dataset", "created": "2016-12-30", "language": "fre", "title": "CARBIOSOL - Total organic carbon stocks - period 2005-2014", "description": "Cette couche de donn\u00e9es spatialise les stocks de Carbone Organique total (COT) des sols agricoles du territoire wallon.\n\nLa qualit\u00e9 d\u2019un sol peut \u00eatre \u00e9valu\u00e9e gr\u00e2ce \u00e0 l\u2019\u00e9tude de divers param\u00e8tres physiques, chimiques ou biologiques.

Le r\u00e9sultat en sortie du mod\u00e8le est une couche raster des stocks de COT (dans les trente premiers centim\u00e8tres du sol) \u00e0 40 m\u00e8tres de r\u00e9solution et spatialement continue sur l'ensemble du territoire agricole wallon. \n\nPour plus de d\u00e9tails sur la constitution des couches cartographiques g\u00e9n\u00e9r\u00e9es dans le cadre du projet CARBIOSOL, veuillez-vous r\u00e9f\u00e9rer \u00e0 la fiche de m\u00e9tadonn\u00e9es documentant la s\u00e9rie de couches de donn\u00e9es.\n\nPour l'\u00e9tude relative aux stocks de COT, les donn\u00e9es utilis\u00e9es en entr\u00e9e du mod\u00e8le sont :\n- des mesures (observations) de stock de carbone organique total du sol en chaque site d'\u00e9chantillonnage du r\u00e9seau de surveillance des sols (RSS) CARBOSOL pour la p\u00e9riode 2005-2014. Le stock de COT est calcul\u00e9 suivant une relation consid\u00e9rant i) la profondeur d'\u00e9chantillonnage (m), ii) la teneur en carbone organique total (COT - %C) dans le sol, iii) la proportion volumique en \u00e9l\u00e9ments grossiers et iv) la densit\u00e9 apparente de l'horizon (kg/cm\u00b3).\n\n- les co-variables environnementales : l'altitude, les temp\u00e9ratures et pr\u00e9cipitations, l'occupation du sol, des param\u00e8tres connus des sols (classe de drainage naturel, fractions granulom\u00e9triques, etc.). Ces facteurs ont une influence potentielle sur les stocks de carbone organique.\n\nLes stocks sont exprim\u00e9s en M\u00e9gagramme de Carbone par hectare (MgC/ha). Ils sont utilis\u00e9s pour r\u00e9aliser des bilans Carbone au niveau r\u00e9gional ainsi que pour du reporting europ\u00e9en et mondial.", "formats": [{"name": "TIFF (.tif"}, {"name": " .tiff)"}, {"name": "WWW:LINK"}, {"name": "ESRI:REST"}, {"name": "OGC:WMS"}, {"name": "atom:feed"}], "keywords": ["Nature et environnement", "Sol et sous-sol", "Sols", "dynamique naturelle", "biologie", "sol", "biologie du sol", "for\u00eat", "cycle du carbone", "d\u00e9terioration du sol", "organisme du sol", "structure du sol", "carbone organique", "d\u00e9gradation du sol", "fertilit\u00e9 du sol", "carbone", "mati\u00e8re organique", "chimie des sols", "sol", "prairie", "carbone organique total", "BDInfraSIG", "Extraction_DIG", "Reporting INSPIRE", "WalOnMap", "Open Data", "PanierTelechargementGeoportailNO", "Digital Soil Mapping", "carbiosol", "carbosol", "teneur en carbone", "Aardewerk", "horizon de surface", "sol", "COSW", "DTM", "mod\u00e9lisation", "COT", "CO2", "horizon de sol", "R\u00e9gional", "Observation de la terre et environnement", "2023/138"], "contacts": [{"name": null, "organization": "Helpdesk carto du SPW (SPW -
