Brief Project Summary:

Soybeans need iron to make chlorophyll for photosynthesis. In soils high in calcium carbonate and pH, many soybean varieties struggle to take up iron. Iron deficiency chlorosis shows up as interveinal yellowing of young leaves, and variety selection is the primary management option. This project evaluates other management factors known to help alleviate IDC symptoms together. It compares seven cropping systems using different combinations of management practices to learn what helps reduce the impact of IDC. Trials incorporate various combinations of crop rotations, oat cover crops, higher seeding rates and compaction with a roller packer.

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.
