Gypsum (calcium sulfate)
Supplies: 1 ton bulk / Bag
Weight : 1000 ton
Pure gypsum is a white-to-transparent mineral, though impurities can give the mineral a gray, brown, or pink coloration. Its chemical name is calcium sulfate dihydrate,and its chemical formula is CaSO4•2H2O. When gypsum is heated, it loses approximately three-quarters of its water and becomes hemihydrate gypsum (CaSO4•½H2O), which is soft and can easily be ground to a powder called hemihydrate gypsum plaster or plaster of paris.
Gypsum is not acid soluble and will not change the soil pH. It helps to shift the Ca and Mg levels in soil and offers a readily available form of sulfate sulfur, a valuable secondary nutrient that benefits the soil and crop. The sulfate in gypsum binds with excess Mg in the soil to form soluble Epsom salt, which moves lower into the soil profile. This Mg is replaced by Ca, improving water holding capacity, root development and soil quality.
