Based on extensive prevented plant acreage in the Midwest, the Michael Fields Ag Institute recommends planting warm-season species such as sorghum-sudan which provides rapid soil cover (in 2018 farm trials, a mix of 1/3 sorghum-sudan produced 84% of ground cover in 30 days), greatest dry matter yields, weed suppression and replaces carbon ordinarily provided by corn stover. In addition, the species maximizes nitrogen retention where fertilizer N is applied and is drought tolerant.
