Countryside Survey: Topsoil – Soil pH

Countryside Survey topsoil pH data is representative of 0 – 15 cm soil depth. Topsoil pH was measured using 10g of field moist soil with 25ml de-ionised water giving a ratio of soil to water of 1:2.5 by weight. For topsoil pH data, a total of 2614 cores from 591 1km × 1km 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 GB 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/CaCO3 rank using 2007 data are mapped on to the dominant habitat and CaCO3 rank in each 1km × 1km square derived from the Land Cover Map 2007 and Parent Material Model 2009, respectively. The parent material characteristic used was that which minimised AIC 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.
