ABSTRACT

For those soils that require deep tillage to alleviate soil compaction, subsoiling can be an expensive and time-consuming tillage event. Alternative tillage methods are needed which conserve natural resources without sacrificing cotton yields. An experiment was conducted in the Tennessee Valley Region of North Alabama to determine how frequently deep tillage is needed to alleviate soil compaction problems in these soils. Results over a two-year period that consisted of cotton (Gossypium hirsutum L.) yields resulting from tillage three-years previous, two years previous, and one year previous found no differences in crop yield. No differences between four tillage implements were also found with all tillage treatments resulting in similar yields.
