Change the timing of ploughing
A replicated site comparison study, from 1984 to 1996 on silty clay loam soils in southern Norway, found that spring tillage reduced annual soil loss by 90% compared with autumn tillage. Variations in winter climate (e.g. rainfall) also influenced soil loss. There were six sites, with varying plot size: Bjørnebekk (144m2, 11 replicates), Syverud (210m2, 12), Askim (147 and 267 m2, 6), Øsaker (176 m2, 8), Hellerud (180, 720, 816 m2, 8), Holt (2.7 ha catchment, not replicated). The tillage treatments were autumn ploughing, spring ploughing, autumn harrowing, spring harrowing, and direct drilling. Runoff and amount of eroded soil was measured.

Change tillage practices
A replicated site comparison study, from 1984 to 1996 on silty clay loam soils in southern Norway (Lundekvam & Skøien, 1998) found that autumn harrowing reduced soil loss by 20-60% compared to autumn ploughing. Variations in winter climate (e.g. rainfall) also influenced soil loss. There were six sites, with varying plot size: Bjørnebekk (144m2, 11 replicates), Syverud (210m2, 12), Askim (147 and 267 m2, 6), Øsaker (176 m2, 8), Hellerud (180, 720, 816 m2, 8), Holt (2.7 ha catchment, not replicated). The tillage treatments were autumn ploughing, spring ploughing, autumn harrowing, spring harrowing, and direct drilling. Runoff and amount of eroded soil was measured.
