This project has a primary objective that will evaluate the impact, on soybean yields, of direct versus residual phosphorus (P) and potassium (K) applications; and, determine the optimum timing, placement and rate of P and K necessary to optimize yield and quality of soybeans that are grown in rotation with corn. In addition, the incline and decline rates of soil P and K tests as influenced by fertilizer rate and nutrient removal in the grain will be determined. Additional objectives will evaluate response of soybeans to broadcast applications of micronutrients and evaluate differences in mid-season tissue nutrient concentrations between soybean varieties. This project will also evaluate...
Updated recommendations for the nutrient management of soybean.
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.
