Soil loss and runoff from simulated rain were measured from eight tillage systems on a Catlin silt loam soil in central Illinois. For each tillage system two plots were row cultivated five weeks after planting and two plots were not cultivated. At the time of rainfall simulation, a surface crust was apparent on the non-cultivated plots. Runoff from the cultivated plots was significantly less than from the non-cultivated plots for seven of the eight tillage treatments tested. Significant reductions in nutrient loss were observed for four of the tillage treatments. The effect of cultivation on soil loss was not statistically significant. In a companion study, corn grain yields from four tillage treatments on a Drummer silty clay loam soil were measured. Yields from cultivated plots were significantly higher than non-cultivated plots for one year of the three year study.
