We just can't tell you all the great benefits of gypsum, so we get really excited when someone else presents information on gypsum.

One person who has done some great research is L. Darrell Norton of the National Soil Erosion Research Laboratory.

Darrell conducted a two-year demonstrating successful results in reducing runoff volumes in agricultural applications. Addition of Gypsum to the soil not only improved infiltration, but also reduced run-off concentrations of Phosphorous and Atrazine. The study concluded that use of the gypsum amendment during application of fertilizer and herbicide treatments is a practical management approach in making agriculture more sustainable with respect to surface water quality. The findings were presented at the 9th Biennial Conference on Stormwater Research and Watershed Management.
