Brief Project Summary:

Soybean yields have increased substantially due to better management of improved varieties. One question is, “Are Clemson’s current potassium fertilizer recommendations good enough to sustain high soybean yields?” Previous research conducted in-depth work on evaluating K recommendations and plant analysis to optimize yield. This project expands that work to on-farm trials and verifies if results obtained at on-station trials are aligned with the results of on-farm trials. This helps create more robust datasets testing K fertility recommendations across production environments. The research will generate new information by evaluating the response of soybean yield across four application rates, determining K removal values for soybean and correlating the trifoliate leaf K concentration with soil test levels.

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.
