Abstract
A tillage study was conducted on a Hubbard loamy sand soil in central Minnesota. Tillage regimens included moldboard plowing followed by a furrow press type packer, chisel plowing, no-till or direct planting and ridge planting. All operations were conducted in the spring for corn and soybeans grown in rotation on irrigated 47 m by 15 m plots. A compacted layer, mean cone index 2200 kPa, exists at a depth of 24 cm for the moldboard plow, no-till and ridge regimens, possibly as a result of the previous years' moldboard plowing. Yield differences were not attributed to the compacted layer measured in the wheel track spaces between rows.
