Soil erosion at Albourne, West Sussex, England

Few measurements of the rate of soil erosion from agricultural land in Britain have been published. Loamy soils in England may be particularly vulnerable to erosion. Thus, in a field of strawberries near Albourne at least 181 t ha⁻¹ of fine loamy soil was eroded in a 9-month period; this is almost 100 times greater than a suggested ‘acceptable’ figure. Factors which have induced erosion at Albourne are: the removal of field boundaries; the choice of crop which left the ground bare for a prolonged period ; and the working of the land downslope. Other factors contributing to erosion are the low clay and organic matter content of the soil. The soil slakes and the resultant crust reduces the rate of infiltration of rainfall into the soil and this produces overland flow. Large amounts of rainfall are not necessary to cause erosion. Erosion in the Albourne area is probably a relatively recent phenomenon brought about by changes in land use.
