Use crop rotation
A randomized, replicated, controlled experiment in 1991-1992 on a silty loam in Ontario, Canada (Rasiah & Kay 1995) found that including forage crops in crop rotations and minimizing tillage reduced rainwater runoff by 70% and 27%, and soil loss by 87% and 63%, respectively, compared to continuous cropping of maize Zea mays. Treatments included alfalfa Medicago sativa or bromegrass Bromus inermis followed by maize, and a continuously cropped, conventionally tilled maize control. Forage crops were grown for either two, four or six years prior to the reintroduction of maize. There were four replicates. A rainfall simulator was used to simulate rain events at 16 mm/h in 1 m2 subplots within each treatment. Runoff and soil lost from plots were collected manually. The results did not distinguish between forage crops.
