Soil organic carbon and soil organic matter measurements across habitats from the UK and Spain

This dataset includes measurements of total soil carbon, soil organic carbon and soil organic matter for soil samples from Spain (AI4SoilHealth project), England (Biosoil project) and the UK (CINAg project). Soils were sampled to different depths based on the project’s requirements. The datasets is part of a bigger dataset to investigate the fraction of soil organic carbon (SOC) in soil organic matter (SOM), denoted as , as a national-scale soil process indicator.
