The researchers will determine if the observed K deficiencies seen in soybeans under no-till and strip-till in the region are impacting soybean yields, if the deficiencies seen are reducing yields, and if they can be corrected through the additions of starter fertilizer where the soil test level is above the critical level. Experiments will be conducted to determine if broadcast applications of K or combinations of band and broadcast applications will correct the observed deficiencies when soil test levels are below the current critical level. Since the problem cannot be corrected with current practices, we will determine if deep banding under the row and/or building soil test levels are...
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.
