Brief Project Summary:

Recent research in Indiana and Kansas have confirmed that one of the most limiting factors to high yield in glyphosate resistant soybean systems is a suspected micronutrient deficiency resulting from applications of glyphosate to soil, weed and directly to glyphosate resistant soybeans. Manganese concentrations in soybean plants are frequently lower than optimum, particularly in the week or two following post-emergence glyphosate application. It has been identified that glyphosate reduces the uptake and that glyphosate is toxic to soil microbes that reduce soil manganese into a form that is available for plant uptake.

The objectives of this project are to quantify the effect of glyphosate...

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.
