One ton of anhydrite has more calcium than one ton of gypsum because gypsum is about 21% water by weight. This yields more calcium per ton in a soil application. Anhydrite also has a higher solubility, which helps it benefit the soil quickly. Small amounts of anhydrite are used as drying agents in plaster, paint, and varnish.
