Cover Crop and Minimum Tillage Effects on Yield, Irrigation Water Use, and Net Returns

The addition of cover crop and minimum tillage to current row-crop production practices in the mid-southern United States could holistically improve the sustainability of these farming systems. Soil organic matter is relatively low compare with other regions of the country because of soil type, wet climate, high humidity, and high temperatures, in addition to the removal of carbon as crop residue at harvest. Limited studies have been conducted in the mid-South to quantify the expected benefits of cover crop – minimal tillage systems. Thus, this study was conducted to quantify the benefits of cover crop – minimal tillage systems in the mid-southern United States at field scale.
