Brief Project Summary:

LibertyLink soybeans are a relatively new herbicide tolerant crop option that growers can consider when choosing to plant soybeans. Understanding how to optimize this technology is crucial to the longevity of the system, not just from a perception basis, but also from a resistant management standpoint.

Information And Results
Project Deliverables

Iron fertilizers sold for soil application can range from very effective to completely ineffective. One iron fertilizer, FeEDDHA, is generally considered to be the most effective. Unfortunately, the quality of FeEDDHA fertilizer varies. Most commercial materials 6% Fe, with 40-80% of that held by the "good" isomer, ortho- ortho-FeEDDHA. Crop response to a poor-quality FeEDDHA product
is poor. Three FeEDDHA fertilizers of differing quality were applied to the soil at 0, 10, and 20 milligrams per pot. The higher the ortho-ortho-FeEDDHA content of the fertilizer, the better the crop response.

Final Project Results

In total, we performed about 2,000 different soil-stability evaluations. We calibrated the test against samples of known ortho-ortho-FeEDDHA content, and against response of soybeans in the greenhouse to iron fertilizers of varying quality.

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.
