QUESTIONS THIS PROJECT WILL ADDRESS

  • How does cereal rye influence soil N and S availability and uptake by soybean after termination?
  • Does supplemental N and S impact soybean yield response?
  • Incorporating more cover crops is a key tool to meet Illinois’ nutrient loss reduction goals. While the impact of cereal rye on corn production has been well studied, there is minimal research around managing soybeans after a cereal rye cover crop. In particular, little is known about how cereal rye affects soil N and S availability for soybean uptake after cereal rye termination. In addition, there are questions about soybean yield response to supplemental N and S fertilization.
  • Researchers will gain a better understanding of the situations that could impede soybean development and yield following cereal rye and develop adaptive management to mitigate N and S deficiencies. Thus, farmers will have access to management strategies to maintain or improve soybean yield and quality when coupled with cereal rye.
