Ground Drywall Increases Crop Yield

News Briefs

A study done at the State University of New York, College of Environmental Science and Forestry, concluded that ground drywall applied to soils in test plots increased crop yield by 25% over untreated soil. This result was similar to the benefits of applying limestone or agricultural gypsum to the soil in equivalent quantities (11 tons per acre). The crop was also tested for heavy metals, which occur in drywall in trace quantities. No increased levels were detected. From
