Many soybean producers in Alabama have adopted some form of conservation-tillage. Research has shown that by letting winter cover crops grow longer, improvements in soil quality including organic matter, water filtration and availability, and weed suppression can be attained. However, research has also shown that surface residue can decrease the value/effectiveness of preemergence herbicides. Because winter cereal cover crops can provide early season weed control when managed properly, the question becomes can preemergence herbicides be replaced with a high-residue winter cover crop. This research project will address the question whether herbicide inputs can be successfully reduced...
