American Society of Agronomy webinar sponsored by GYPSOIL brand gypsum. For more information about the use of gypsum to improve agricultural soils, visit gypsoil.com.
The NRCS practice standards for amending soils with gypsum were updated in April 2015. This webinar will acquaint the CCA with these standards, and how they are applied in humid-region, non-sodic soils. Researchers will discuss the latest research addressing results of gypsum applications as they pertain to the NRCS standards. These standards include:
- Improve soil health by improving physical/chemical properties and increasing infiltration of the soil.
- Improve surface water quality by reducing dissolved phosphorus concentrations in surface runoff and subsurface drainage.
- Improve soil health by ameliorating subsoil aluminum toxicity.
- Improve water quality by reducing the potential for pathogens and other contaminants transport from areas of manure and biosolids application.

Dr. Warren A. Dick
The Ohio State University
Warren Dick grew up on a diversified farm in North Dakota. He graduated from Wheaton College (BS) and Iowa State University (MS and PhD). Warren is a professor of soil and environmental science. He studies enzymatic and biological nutrient cycling in soil under various management systems. Recent research has focused on the use of gypsum for improving soil and water quality. Warren has mentored more than 35 graduate students, 12 undergraduate interns, 8 postdocs and 27 visiting scholars. He has published 31 papers that have been cited more than 100 times. He is active professionally and has served as Editor-in-Chief of both the Soil Science Society of America and the American Society of Agronomy.
Dr. H. Allen Torbert
Dr. H. Allen Torbert is a Soil Scientist and the Research Leader (Location Coordinator) for the USDA-ARS National Soil Dynamics Laboratory in Auburn, AL, where he manages human and physical resources as well as research activities. He earned his B.S. (1983) and M.S. (1985) degrees from Auburn University’s Agronomy and Soils Department and his Ph.D. degree from the University of Illinois in the Agronomy and Soils Department (1989). After a Post Doctorate in Auburn, Dr. Torbert served as a Soil Scientist at the USDA-ARS Grassland Soil and Water Research Laboratory in Temple, TX. In 2001, Dr. Torbert returned to Auburn as a Soil Scientist and was appointed Research Leader in 2005 for the National Soil Dynamics Laboratory. Dr. Torbert’s program focuses mainly on soil fertilizer practices to develop cropping systems that optimally integrate animal manure into sustainable agriculture while safeguarding environmental integrity. This includes developing knowledge regarding the relationship of agriculture to global environmental change. He has authored or co-authored 252 publications; including 152 refereed journal articles, 16 book chapters, 84 publications in proceedings of national and international meetings, and has 1 patent (2 pending). He has received 41 Competitive Grants, totaling $9,187,000. Dr. Torbert currently serves on the editorial board of Pedosphere, and European Agrophysical Journal, and the Journal of Soil and tillage Research. He is active in the International Soil Tillage Research Organization. Dr. Torbert also is an affiliate faculty member at Texas A&M University and Auburn University and has served on several graduate student committees in the Crop, Soil and Environmental Sciences Department, Horticulture Department, and the Department of Entomology and Plant Pathology at Auburn University.
Agronomist and Founder
GYPSOIL chief agronomist and founder Ron Chamberlain first saw the improvement in soil structure that gypsum brought to his clients’ farms in the early 2000s. He observed that soils became softer and more friable, yet they resisted compaction, crusting and ponding. Over time, clients reported crop performance had improved because of the healthier, more productive soils. Chamberlain established a gypsum business in 2002 and sought permits to sell gypsum for agricultural purposes in Indiana, establishing the GYPSOIL brand in 2006. In June 2009, Chicago-based Beneficial Reuse Management (BRM) acquired GYPSOIL and Ron became Director of Gypsum Programs for BRM. He continues to serve as the lead agronomist for GYPSOIL and travels throughout the Midwest, Southeast and Mid-South to assist employees and customers who are incorporating GYPSOIL into their management program. Ron has worked in agriculture in the US and abroad for over 40 years.
