Adaptive Management for Maximizing Soybean Production Following Cereal Rye Termination

Trials in this multi-year project will help researchers better understand 1) how cereal rye influences nitrogen (N) and sulfur (S) availability and soybean uptake, and 2) evaluate soybean yield response to N and S fertilization, alone and in combination, after a cereal rye cover crop.

Project Information

  • 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?
  • On-farm location in Effingham County (Year 1)
  • University of Illinois Crop Sciences Research & Education Center, Urbana (Years 1 & 2)
  • University of Illinois Northwestern Illinois Agricultural Research & Demonstration Center, Monmouth (Year 2)
  • University of Illinois Orr Agricultural Research & Demonstration Center, Perry (Year 2)
  • University of Illinois Ewing Demonstration Center, Ewing (Year 2)
  • 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.
  • 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.
  • Collected data from the 2023 growing season will be analyzed during winter 2023-2024
