Incorporation of Surface-Applied Materials by Tillage Implements

Maximum depth and uniformity of incorporation of surface-applied materials by rotary tillers, a spading machine, and a disc cultivator were compared in Wisconsin nursery (loamy sand soil) and Michigan nursery (sandy loam soil) trials using ceramic sphere tracers (1 - 3 mm dia). The tracers or beads were spread uniformly over the soil surface and different tillage implements were then operated through these areas as they traveled the length of each study field. Results of these trials are applicable to situations involving incorporation of such materials as granular fumigants or herbicides, granular fertilizers, peat, and cover crop residues.
