Countryside Survey: topsoil carbon — carbon density

Countryside Survey (CS) topsoil carbon density (t ha-1) data is representative of 0 – 15 cm soil depth. Carbon density was estimated by combining carbon concentration (g kg-1) with bulk density (g cm-3) estimates. For topsoil carbon data, a total of 2614 cores from 591 1 km x 1 km squares across Great Britain were collected and analysed in 2007. Please see Emmett et al., 2010 for further details of sampling and methods.

Estimates of mean values within selected habitats and parent material characteristics across Great Britain were made using CS data from 1978, 1998 and 2007 using a mixed model approach. Please see Scott, 2008 for further details of similar statistical analysis.

The estimated means of combinations of broad habitat/calcium carbonate (CaCO3) rank using 2007 data are mapped on to the dominant habitat and CaCO3 rank in each 1 km x 1 km square derived from the Land Cover Map 2007 and Parent Material Model 2009, respectively. The parent material characteristic used was that which minimised AIC (Akaike information criterion) in each model. Areas such as urban and littoral rock are not sampled by CS and therefore have no associated data. Also, in some circumstances sample sizes for particular habitat/parent material combinations were insufficient to estimate mean values. Where these areas occur they are left blank.
