Abstract
After seven years of reduced tillage practice, a compacted layer (mean cone index 220 N/cm**2 ) exists for moldboard plow, ridge and no-till, possibly as a result of previous years' moldboard plowing. Yield differences were not attributed to the compacted layer on the Hubbard loamy sand where research plots are located.
