The soil is of the Compton Series. Soils of this series are clayey and often waterlogged and are developed in reddish river alluvium subject to seasonal waterlogging. They occupy low-lying flat ground along the floodplains of rivers particularly in southwestern England.They have prominently mottled reddish and greyish subsoils which usually pass down into permanently waterlogged greyish clay layers. The soils have a clay content often in excess of 60 percent and a pH of above 7 in the B horizon.They are mostly, as is this particular profile, under permanent grass as prolonged waterlogging at shallow depths and risk of seasonal flooding generally precludes arable crops. Compton soils are classified as Fluvic Gleysols (WRB); and as Peloalluvial Gley Soils (Avery, England and Wales)
