Profit maximizing winter cover crop, tillage and nitrogen fertilization systems for cotton

摘要

Winter cover crops and conservation tillage can benefit soils in cotton production. This study evaluated how alternative winter cover crops and tillage affect profit maximizing nitrogen fertilization rates and net revenues for cotton production in West Tennessee. Net revenues for vetch and the other winter covers was less than for cotton with no cover. Consequently, producers may not adopt winter covers for conservation purposes because net revenues are lower with winter cover crops.
