Synopsis Deep tillage lowered bulk density and improved permeability in the dense layers. When subsequent tillage erased the chisel or subsoiler marks, deep tillage did not improve moisture movement into the soils nor did it increase moisture storage. Crop yields seldom were increased by deep tillage. Deep placement of fertilizer did not prove superior to surface applications in most instances. In no case did deep tillage or deep fertilizer placement increase the profit from crop production.
