This project will study a number of nutrient management issues in soybeans. Objectives of this project include: 1) The evaluation of crop response to sulfur fertilization on different soils of a landscape; 2) The evaluation of interactions between nitrogen, phosphorus and sulfur fertilization in a rotation on grain yields and quality; and, 3) Determination of optimum timing, placement and fertilization rates for phosphorus to optimize yields in the rotation. An additional objective for 2009 is to develop recommendations on how to use cover crops and Soygreen to reduce the severity of iron deficiency chlorosis in soybeans.
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.
