Brief Project Summary:

The primary goal of this research is to raise the soybean yield potential in dry seasons on fragipan soils. Fragipan soils make up a significant portion of Kentucky?s cropland. The most significant limitation associated with soybean production on fragipan soils are excessive wetness in the spring and increasing probability of crop moisture stress in the summer. Both limitations are due to presence of fragipan and both limitations become more severe as the depth of the fragipan soil becomes shallower.

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.
