Brief Project Summary:

The goal of this new project is to better understand relationships between potassium (K) fertilization, grain yield, K uptake and removal, K recycling with residue, and K distribution into soil pools to improve the efficacy of K management and economic benefits from fertilization. The project began in October 2008, and this goal will be achieved by using a combination of new short-term conventional plot experiments and sampling of selected plots of ongoing long-term experiments that were established years ago with partial support from ISA.

Final Project Results

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.
