Brief Project Summary:

Recent research has indicated that one of the possible factors limiting yield of glyphosate resistant soybean may be a micronutrient deficiency. Manganese concentrations in soybean plants are frequently lower than optimum, particularly in the week or two, following post-emergence glyphosate application. It has been shown that glyphosate reduces the uptake and translocation of manganese via physiological immobilization of manganese in soybean plants and that glyphosate is toxic to soil microbes that reduce soil manganese to a form that is available for plant uptake.

The objectives of this project is to quantify the effect of glyphosate on manganese availability in glyphosate-resistant...

Information And Results
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.
