This dataset presents modelled estimates of soil carbon concentration (g kg-1) at 1km2 resolution across Great Britain. A Generalized Additive Model approach was used with Countryside Survey soil carbon data from 2007 and including climate, atmospheric deposition, habitat, soil and spatial predictors. The model is based on soil carbon data from 2446 locations across Great Britain and is representative of 0-15 cm soil depth. Loss-on-ignition (LOI) was determined by combustion of 10g dry soil at 375 degrees Celsius for 16 hours; carbon concentration was estimated by multiplying LOI by a factor of 0.55. The Countryside Survey looks at a range of physical, chemical and biological properties of the topsoil from a representative sample of habitats across the UK.

Provenance & quality

The data used to model soil carbon concentration are taken from the Countryside Survey. The technical reports by Emmett et al. (2010) present full methodological details for the Countryside Survey soil sampling and analytical processes, and can be found at: http://nora.nerc.ac.uk/id/eprint/9354/1/CS_UK_2007_TR9.pdf.
