Develop regional agronomic recommendations to help farmers incorporate a cereal rye cover crop after corn grain without negatively impacting the subsequent soybean crop, and to use the cover crop to improve weed control and soil health.
This is a multi-site study (two research farms [Morris and Crookston, MN] and seven field-scale on-farm experiments). ARS will help facilitate one of the research farm studies at the Swan Lake Research Farm (Morris). Research farm treatments include three factors: Tillage treatments: 1. Fall chisel plow and field cultivation 2. No-till Cover crop seeding rate treatments: 1. no cover crop 2. 20 lb/A cereal rye 3. 40 lb/A cereal rye Cover crop termination timings: 1. 1-2 weeks before soybean planting 2. at soybean planting 3. 1-2 weeks after soybean planting
