Brief Project Summary:

This project intends to re-evaluate the soil fertility recommendations for Ohio soybeans, focusing specifically on phosphorous and potassium and the role fertility plays in soybean resistance to pests and disease. It takes a multi-faceted approach to examine soil fertility rates with pest and disease interactions over both research and farm fields. Research should determine economically optimal P and K fertilization rate for soybeans in Ohio by refining yield response curves, region-specific and soil type-specific calibration curves of Bray P to Mehlich P soil levels in Ohio and the impact that soil fertility levels have on populations of and corresponding yield reductions caused by SCN, soil borne pathogens and insect pests.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
Project Deliverables

1. Recommendations for optimal P & K fertilization rate for soybeans in Ohio.
2. More accurate calibration curves of Bray P to Mehlich P soil levels in Ohio.
3. Increased knowledge of the impact of soil fertility levels on populations of and corresponding yield reduction caused by SCN, soil borne pathogens and insect pests.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
