Abstract
An experiment was conducted on a 2-5% sloping Mercer silt loam soil on a farm in Bourbon/Harrison Counties where very poor corn was grown in 1984 because of soil compaction and drought. Soil test levels of the experimental area were: pH 4.8. and 99, 316, 2070. and 120 lbs/A of P, K, Ca, and Mg, respectively. Examination of the field showed that the compacted zone occurred uniformly in the 0-5 inch surface layer of soil. Cause of this compacted layer was thought to be due to excessive disk tillage in prior years when preparing the field for tobacco production and to winter grazing of a wheat cover crop. The objective of the experiment was to evaluate the influence of fall or spring plowing with a paraplow. chisel plow, or moldboard plow on plowsole bulk density and corn production.
