Planting soybeans within one day of terminating a cereal rye cover crop does not reduce yield and can improve weed control compared to terminating the cover crop 10–14 days prior to planting soybeans. In experimental trials, farmer-cooperators Jack Boyer and Tim Sieren compared two cereal rye cover crop termination dates: early (near the time of planting soybeans) and late (three to four weeks after planting soybeans).
