An area of about 24 km(2) in arable East Lothian, Scotland, was examin
ed for soil erosion by water following a severe rainstorm in October 1
990. Significant erosion was found in only 10 fields out of 265 in an
area where topography, soils and cropping suggest a high erosion risk.
Doubt is cast on some assessments of the widespread risk of significa
nt soil erosion by water in arable areas of the UK.
