The period covered by this map is from February 1949 to July 1972. The layer was created by spatial modelling method developed by UCL in the framework of the CARBIOSOL convention.  For more details on the mapping layers generated in the CARBIOSOL project, please refer to the metadata sheet documenting the data layer series.  In each pixel, the total organic carbon (TOC) content is expressed in grams of carbon per kilogram of dry fine earth (gC/kg). The output of the model is a raster layer of TOC contents at 90 meters resolution and spatially continuous on the Walloon agricultural territory.  The average TOC levels for soils under crops and grasslands over the period 1949-1972 were 1.62 gC/kg and 3.26 gC/kg. During this period, 9% of agricultural areas had TOC contents < 1.15 %C and 60% had contents < 1.5 gC kg-1. Below 1.15 gC/kg, the soil is destructured.  Soil TOC levels for both soil occupations tend to increase from north-west to south-east, from the sandy-loamy region to the Ardennes region, and decrease in the Jurassic region. This trend reflects variations in landforms and soils that also control changes in land cover (from intensive crops to dominant extensive permanent grassland), but also climatic variations.", "formats": [{"name": "WMS_SRVC"}], "keywords": ["High value dataset", "aardewerk", "analyse-des-sols", "be", "biologie", "biologie-du-sol", "carbiosol", "carbone", "carbone-organique", "carbone-organique-total", "carbosol", "cartogramme", "cartographie", "cnsw", "co2", "conservation-du-sol", "cos", "cosw", "cot", "covariable", "culture", "cycle-du-carbone", "digital-soil-mapping", "donne\u0301es-sur-l'e\u0301tat-de-l'environnement", "dtm", "dynamique-naturelle", "erreur", "fore\u0302t", "gam", "horizon-de-sol", "mag", "matie\u0300re-organique", "mode\u0300le-additif-ge\u0301ne\u0301ralise\u0301", "mode\u0301lisation", "monte-carlo", "organisme-du-sol", "prairie", "profil-du-sol", "qualite\u0301-du-sol", "requasud", "ressources-du-sol", "re\u0301gional", "re\u0301seau-de-mesure", "rmse", "rss", "sol", "sols", "sous-sol", "station-de-surveillance", "stockage", "surveillance-de-l'environnement", "teneur-en-carbone", "type-de-sol", "utilisation-du-sol"], "contacts": [{"organization": "Helpdesk carto du SPW (SPW - Secr\u00e9tariat g\u00e9n\u00e9ral - SPW Digital - D\u00e9partement Donn\u00e9es transversales - Gestion et valorisation de la donn\u00e9e)", "roles": ["creator"]}, {"organization": "https://org.belgif.be/id/CbeEstablishmentUnit/2204322327", "roles": ["publisher"]}]}, "links": [{"href": "https://geoservices.wallonie.be/geoserver/inspire_so/ows?service=WMS&version=1.3.0&request=GetCapabilities"}, {"href": "https://metawal.wallonie.be/geonetwork/srv/api/records/ce58c3ed-03d5-43da-b5cf-376e8faf351c"}, {"href": "http://data.europa.eu/88u/dataset/https-geodata-wallonie-be-id-ce58c3ed-03d5-43da-b5cf-376e8faf351c"}, {"href": "https-geodata-wallonie-be-id-ce58c3ed-03d5-43da-b5cf-376e8faf351c"}, {"href": "https://geodata.wallonie.be/id/ce58c3ed-03d5-43da-b5cf-376e8faf351c"}, {"rel": "self", "type": "application/geo+json", "title": "0324a8af62bad2addc403a850dfc8280", "name": "item", "description": "0324a8af62bad2addc403a850dfc8280", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/0324a8af62bad2addc403a850dfc8280"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"null": "date"}}], "links": [{"rel": "self", "type": "application/geo+json", "title": "This document as GeoJSON", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=teneur-en-carbone&f=json", "hreflang": "en-US"}, {"rel": "alternate", "type": "text/html", "title": "This document as HTML", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=teneur-en-carbone&f=html", "hreflang": "en-US"}, {"rel": "collection", "type": "application/json", "title": "Collection URL", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main", "hreflang": "en-US"}, {"type": "application/geo+json", "rel": "first", "title": "items (first)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=teneur-en-carbone&", "hreflang": "en-US"}, {"rel": "last", "type": "application/geo+json", "title": "items (last)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=teneur-en-carbone&offset=6", "hreflang": "en-US"}], "numberMatched": 6, "numberReturned": 6, "distributedFeatures": [], "timeStamp": "2026-09-21T06:59:20.086043Z"}
