Biological Systems Engineering: Papers and Publications

This rainfall simulation study provided information on the effects of 0.72 m (2.4 ft) wide switchgrass hedges located at the bottom of plots on runoff an soil loss under both no-till and tilled conditions. The study area, which had slopes ranging from 8 to 16%, had produced corn for 33 years and the grass hedges had been established for 6 years. Simulated rainfall [64 mm hr^-1)] was applied for two hours to plots [3.7 m (12 ft) wide by 10.7 m (35.1 ft) long] with corn residue and to plots where corn residue was removed. The narrow grass …
