Countryside Survey: topsoil — bulk density

Countryside Survey (CS) topsoil bulk density (g cm-3) data is representative of 0 – 15 cm soil depth. Bulk density was estimated by making detailed weight measurements throughout the soil processing procedure. For topsoil bulk density 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 1998 and 2007 using a mixed model approach. Please see Scott, 2008 for further details of similar statistical analyses.

The estimated means of combinations of broad habitat/dominant grain size class using 2007 data are mapped on to the dominant habitat and dominant grain size class 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.
