The focus systems are prevalent row crop systems in the Lower Coastal Plains of the Southeastern U.S. These include major crops such as cotton, peanut, corn, soybean, and sorghum, along with various emerging summer crops. Approximately 5% of row cropland is used for winter crops such as rye, oats, triticale, and wheat, most of which are terminated before the summer cash crops are planted. Livestock grazing on winter crops is limited. Therefore, prevailing systems typically involve summer crop rotations with fallow winters, whereas winter cropping systems refer to those that generate revenue and ecosystem services through either harvested winter crops or winter crop grazing.
