ABSTRACT:
Runoff from natural and simulated rainfall on 0.10-hectare (0.25-acre) plots was analyzed to evaluate soil losses from soybean plots and five different tillage systems on a highly erodible soil in West Tennessee. Soil losses generally were greatest for the conventional-till, single-crop soybean system, followed in order by drilled soybeans; conventional-till, double-cropped soybeans; no-till, double-cropped soybeans; and no-till, single-cropped soybeans. Results are reported for selected storms in the 3-year period 1980–1982. Energy requirements were also monitored and fuel consumption for various tillage practices is presented.
