Gypsum - Application Tips

GYPSOIL is best applied with a fertilizer or litter spreader, ideally equipped with a stainless steel box with steep sides (45°angles) and a wide belt. In absence of a stainless steel box, graphite film coating or plastic liners can be used to assure the gypsum slides easily onto the belt.

Gypsum Mineral Uses and Properties

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
