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.

Information And Results
Project Summary

Determine effect of selected cropping systems on yield of IDC-tolerant and -intolerant soybean varieties, and evaluate soil moisture sensor data relationship to IDC symptoms in these cropping systems.

Project Objectives

Project Deliverables

MAFES and MCES publications that will outline management practices that should be used to stabilize yields from soybeans grown on IDC-susceptible sites.

Final Project Results

Benefit To Soybean Farmers

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.
