This fertility project involves evaluating soybean yield response to P and K fertilization rate and updating current P and K fertility recommendations for soybean that are based on the Lancaster extraction method.
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.
