2011 Symposium

Beneficial Reuse Management LLC

The Midwest Soil Improvement Symposium: Research and Practical Insights into Using Gypsum was a one-day landmark scientific symposium held August 23, 2011, at the University of Wisconsin Arlington Ag Research Station. 

Co-sponsors for the event included the UW College of Agriculture and Life Sciences (CALS); UW-Extension; the Conservation Technology Information Center and GYPSOIL®.

Research indicates that gypsum makes soils more permeable to rainfall, alleviates aluminum toxicity and supplies soils with calcium and sulfur, an often-depleted soil nutrient. Gypsum applications also improve particle aggregation, reduce erosion and have been shown to help keep phosphorus and other nutrients from running off agricultural fields.

GypsoilLeading researchers, gypsum experts and growers experienced using gypsum gave presentations on research findings, application recommendations and background on the production of gypsum in flue gas desulfurization (FGD) systems at certain coal fired utility plants was presented. Information documenting the safety of FGD gypsum use in agriculture was also presented.

Symposium speakers included:

  • Dr. Harry H. Schomberg, Ecologist, J. Phil Campbell, Sr, National Resource Conservation Center, USDA-Agricultural Research Service, Watkinsville, GA;
  • Dr. Warren Dick, Professor, Environmental and Natural Resources, Ohio State University, Wooster, OH;
  • Dr. Dexter B. Watts, Research Soil Scientist, USDA-Agricultural Research Service, Auburn, AL;
  • Dr. Richard Wolkowski, UW-Madison; and Dr. Meghan Buckley of the UW-Stevens Point;
  • Dr. Darrell Norton, Soil Scientist, National Soil Erosion Research Lab, USDA-Agricultural Research Service, West Lafayette, IN;
  • Dr. Rufus Chaney, Research Agronomist, Environmental Management and Byproduct Utilization Laboratory, USDA-Agricultural Research Service, Beltsville, MD;
  • Ron Chamberlain, director of gypsum programs for Beneficial Reuse Management, marketer of GYPSOIL® brand gypsum;
  • John A. Andersen, Jr., President, Greenleaf Advisors Limited, Wilmette, IL, will provide an overview of the environmental impact of agricultural application of byproduct gypsum;
  • Bob Paulson, Environmental Consultant, We Energies, Milwaukee, WI, will give background on gypsum production and supply.

Grower panelists included:

  • Rodney Rulon, Arcadia, IN;
  • Nick Miller, Oconomowoc, WI;
  • Jack Maloney, Brownsburg, IN;
  • Tom Greil, Waterford, WI;
  • Larry Strupp, Slinger, WI;
