Abstract
Information on effects of tillage sweep geometry and operation on soil conditions, including soil surface elevation, is needed for effective design, selection, and use of sweeps for row crop cultivation and ridge construction. The effects of sweep rake angle and of operation speed and depth on changes in soil microtopography were determined. Changes in microtopography due to observed soil aggregate movement were also found. A factorial arrangement of pairs of sweeps with three geometries operated at three speeds (5, 7, and 9 km/h) and at two depths (50 and 100 mm) were used to form ridges in a field experiment.
