Brief Project Summary:

Sulfur deposition from the atmosphere has been declining over the last few decades due to the improvements in air quality, especially the Clean Air Act in 1990. Sulfur is needed in large quantities for all crops including soybeans. Soil organic matter can help make up the difference in crop need and deposition from the atmosphere, but evidence is mounting that more sulfur is needed in some fields. The project aims to determine the best options (e.g., fertilizer sources to be broadcast applied prior to planting, foliar sprays during the growing season) to manage sulfur for soybean and determine opportunities for synergies in management to optimize soybean yield and quality.

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

Information And Results
Project Deliverables

Preliminary results from the 2016 and 2017 seasons have already been shared across Indiana. The results from 2018 will continued to be presented at Extension winter workshops, meetings, and conferences of producers, Extension educators, and crop professionals across Indiana.

Conclusions from the experiments in 2018 and 2019 will be shared with Extension audiences in presentations, newsletter articles, and Web sites. We will also share these findings at the American Society of Agronomy meetings.

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.
