Résumé

In France, soil test results from samples of cultivated topsoil requested by farmers have been collected to constitute the National Soil Testing database (NSTD). Enriching soil maps with such data can be regarded as an important source of information to build GlobalSoilMap products when dense soil profile information does not exist We inferred the soil organic carbon content (SOC) distribution within the soil units of a soil map in a central region of France to re-allocated analyses from NSTD The method is based on a pedological distance between the soil properties (pH, CaCO3 content, cation-exchange capacity, clay content and silt content) of the NSTD and soil map units mean values of the same parameters Results showed a consistent spatial distribution of SOC content
