Electricity "Waste" Powers Crops.
ARS researchers in Indiana have shown that the gypsum helps soil take in more water by preventing soil from crusting, so more rainwater enters the soil, instead of running off. In the past, gypsum from quarries has been used to loosen soil, treat soils high in sodium or toxic aluminum, and fertilize soils with calcium and sulfur deficiencies. At least one Illinois farmer operates a business applying the power-plant gypsum on other farmers' fields. Trucks that used to return empty from the grain elevator now return full--of gypsum.
