Brief Project Summary:

Many soybean growers are interested in using foliar fertilizers, and multitudes of products are marketed to growers. Researchers will evaluate foliar fertilizer products available across the U.S. This will help identify environmental and soil factors where yield response to foliar fertilizers is most likely to occur. The second objective in this project is to study sulfur-containing fertilizers that are surface applied after planting. There is concern about potential sulfur deficiencies in corn and soybeans in the North Central region. Sulfur is relatively immobile within the plant, so deficiency symptoms usually appear in the new growth.

Key Benefactors:
farmers, agronomists, applicators, ag retailers, extension specialists

Information And Results
Project Deliverables

Data will be analyzed both locally and nationally to determine response trends across broad scales. Results will be summarized and disseminated to growers via relevant extension outreach programs (grower meetings, farm shows, SDSU Extension articles, radio spots, social media, etc) and peer-reviewed publications. Research results will be used to create national extension fact sheets detailing Best Management Practices for soybean production. Facts sheets will be national in scope but will address regional consisderations.

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.
