Adaptive Management for Maximizing Soybean Production Following Cereal Rye Termination
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 and seed quality?
WHY THIS RESEARCH IS IMPORTANT
- 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.
HOW THIS RESEARCH BENEFITS THE FARMER
- Agronomists and researchers will gain a better understanding of the situations that could impede soybean development and yield following cereal rye and be better equipped to provide farmers with management recommendations.
- Farmers will gain management strategies that mitigate N and S deficiencies across different soil types and environments so they can better maintain or improve soybean yield and quality when coupled with cereal rye.
INSIGHTS GLEANED TO-DATE
- Collected data from the 2023 growing season will be analyzed during winter 2023-2024
