This layer maps the organic carbon content of the surface soil layer, an indicator of soil fertility and health. Data come from the OpenLandMap Soil Organic Carbon dataset served through Google Earth Engine, at about 250 m resolution. Values are shown in decigrams per kilogram (dg/kg) on a sequential brown scale: lighter tones indicate carbon-poor soils, darker browns indicate carbon-rich, healthier soils.
This layer represents the organic carbon content of the surface soil layer (0 cm), a key proxy for soil fertility, structure and long-term carbon storage. The map is derived from the OpenLandMap Soil Organic Carbon product (OpenLandMap/SOL/SOL_ORGANIC-CARBON_USDA-6A1C_M/v02, band b0) accessed through Google Earth Engine at roughly 250 m resolution. This asset replaced the earlier SoilGrids/ISRIC soc_mean dataset, which is no longer maintained.

The surface-layer soil organic carbon image is clipped to the polygon and its native values in grams per kilogram are multiplied by 10 to obtain decigrams per kilogram (dg/kg), following the Resource Watch convention. The result is rendered with a sequential brown palette normalised over 0 to 4000 dg/kg (legend breaks at 50, 100, 200, 500 and 4000 dg/kg); minimum, maximum and mean values are computed over the valid pixels of each area.
