Abstract:Severe erosion occurred as a result of heavy rainfall on 7 October 1987 and subsequent storms. Rates of erosion were highest on land drilled with winter cereals in the previous three weeks but erosion also occurred on ploughed land. In an area of c36 km2 some erosion was recorded on all cereal fields. Several fields suffered losses >50 m3 ha−1 and rates reached>200 m3 ha−1 on one field. This is the most serious erosion on agricultural land recorded in Britain.In autumn months heavy rain on erodible, silt-rich soils prone to crusting inevitably leads to runoff and high rates of soil loss but a number of factors contributed to the severity of this event: the amount of bare, recently drilled land; the timing of drilling; the size of fields, steepness and length of slopes; the rolling of drilled fields, and the prevalence of wheelings.
