Carbon and nitrogen contents of soil organic matter fractions, soil organic carbon, total soil nitrogen, and soil organic matter of 100 topsoil samples from the UKCEH Countryside Survey, Great Britain, 2019-2020 v2

Carbon and nitrogen content (g per g soil) of the free-light fraction (LF), the occluded particulate fraction (OF), the mineral associated organic matter fraction (MAOM), the particulate organic matter (POM = LF+OF), soil organic carbon (SOC), total soil nitrogen (TN) and soil organic matter (SOM from loss-on-ignition) of 100 topsoil samples (0-15 cm) from the UKCEH Countryside Survey 2019/20 are presented. Associated and historic soil and vegetation data is available through the Countryside Survey data collection: https://catalogue.ceh.ac.uk/documents/2069de82-619d-4751-9904-aec8500d07e6 Full details about this dataset can be found at https://doi.org/10.5285/29cd5386-bc2e-4d70-a6a5-0d7dc7513dc6
