Brief Project Summary:

Several soybean growers in Alabama’s Black Belt Region have installed central pivot irrigation systems in recent years. Irrigation increases soybean yields, but the Black Belt clayey soils are characterized by low infiltration rates, shrink-swell behavior and pronounced surface cracking. For an effective irrigation strategy and to avoid surface water runoff, it is necessary to determine maximum infiltration rates and cracking behavior of the clays in the Black Belt region. This on-farm and extension center research evaluates different irrigation rates for infiltration and surface water runoff using a rainfall simulator. It also assesses dynamics of hydraulic conductivity and plant water uptake.

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.
