Under field conditions, effects of stubble mulch tillage implements on soil cloddiness varied widely from year to year. During initial tillage, 2-inch chisels, 32-inch sweeps, and a one-way disk operated 4 inches deep produced a more cloddy soil surface than a rodweeder with shovels, an 8-foot V-sweep, or a one-way disk operated 2 inches deep. During subsequent tillage, a given implement increased or decreased cloddiness depending on type of previous tillage and soil moisture at time of tillage.
