Brief Project Summary:

A project funded by the Kansas Soybean Commission evaluated the use of secondary and micronutrients for double-crop soybean after wheat. That study suggested some potential trends in plant response particularly for plant nutrient uptake. However extreme conditions of drought and high temperatures the last two years affected yields significantly generating high variability, an issue intensified in the double crop soybean system. The proposed study will emphasize soybean production under optimum conditions, where micronutrients can potentially contribute to maximize yields.

When completed, the information derived from this project will expand producers' knowledge about the potential...

Information And Results
Final Project Results

Preliminary results indicate a large range of soil test values for the different locations of the study in 2013. Results also indicate changes in soil trust values with the application of fertilizer for micronutrients. Most nutrients show a significant change in soil text value (B, Zn, Mn), however in the case of Cu changes were not detected with soil test. This suggests that soil test Cu may not provide a reliable index of Cu level in the soil and potential availability to the plant. Tissue testing results indicate that for some nutrients, tissue testing can potentially provide a better indication than soil test for micronutrients. Yield results across locations didn't show any significant effect, however there was a tendency for higher average yields on the mix fertilizer treatment. Results from the strip trial clearly show the significant field variability on soil test levels for micronutrients. this suggests that management zones for micronutrients may be reasonable for fields with high variability.

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.
