Potassium is a mineral that is often deficient in Kansas soils. This study is directed at developing information on the scope of the problems and solutions needed to maximize soybean yields in Kansas. This project was initiated in 2009 on cooperating farmer's fields in Southeast Kansas. The initial project plan involved establishing K response trials with soybeans on soils varying in K soil test levels and monitoring soybean response to applied K in the year the plot was established. In addition, K soil tests for the control and highest applied rate of K were monitored regularly from initial site selection to date.
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.
