St. Clair County Farm Bureau

FGD gypsum reduces phosphorus runoff and improves soil health

In the fifth virtual field day, St. Clair County farmer Paul Beisiegel and Southern Illinois University Carbondale (SIUC) researcher Karl Williard discuss the use of flue gas desulfurization gypsum to potentially improve water quality, soil structure and crop production in Illinois agriculture. Partners from the Illinois Nutrient Research and Education Council (NREC), Illinois Farm Bureau, St. Clair County Farm Bureau, SIUC, Wyciskalla Consulting and Boral North America all play a role in the research project. Find more details in this booklet, then watch the field day coverage. 

Certified Crop Advisors can receive self-reported Continuing Education Units (CEUs) after watching the videos for each of these virtual field days. For more information, and to find the self-reporting form, visit and click “Self-Report CEUs.”
