The primary component of drywall is the mineral gypsum. It is a light-density rock found in plentiful deposits worldwide. Each molecule of gypsum (or dihydrous calcium sulfate) is composed of two molecules of water (H 2 0) and one of calcium sulfate (CaSO 4 ). By weight the compound is 21% water, but by volume it is nearly 50% water.
Now that we have ascertained what gypsum is, it's natural to question, "Is gypsum good for the soil?" Because it reduces salt levels in soil, it is effective in coastal and arid regions.

Anhydrite can be substituted for gypsum in some of its uses. Both minerals are crushed for use as a soil treatment, and in this purpose anhydrite is superior. 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.
