Brief Project Summary:

The goal of this project is to improve potassium management for soybean production in Kansas, increasing yields with improved diagnostic tools and fertilization strategies based on soil types in the main soybean producing regions in Kansas. Specific objectives include: determining the impact of K deficiencies on soybean yields for different soil types; evaluating current soil test interpretations for K fertilization in soybean, including new soil test methods and the effect of soil clay types on critical levels; assessing plant K levels during the growing season and determining yield limitations related to the high rate of K uptake.

Key Benefactors:
farmers, agronomists, applicators, ag retailers

Information And Results
Project Deliverables

Results will be delivered to Kansas producers and crop advisors in various ways. Information will be disseminated through field days, KSU Soybean Production Schools, extension publications, and the KSU nutrient management webpage. Results of field experiments and any revised recommendations that arise will be summarized and distributed to the public via news releases. Brief articles will be prepared for publication periodically in the Kansas State University Agronomy eUpdates. Results will be shared with county/district extension agents in the state who provide information to soybean growers on a regular basis. Finally, this work will be completed in close collaboration with the KSU soil testing laboratory, and results will be shared with the KSU soil testing lab as well as private laboratories who advise Kansas growers each year.

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.
