Gypsum is calcium sulfate. The most common form of it is the dihydrate which means that each molecule of calcium sulfate has two water molecules associated with it. It is expressed as CaSO42H20. The other form called gypsum anhydrite has no water.Regular use of gypsum is essential to the sustainability of most irrigated soils. Irrigated land eventually leads to sodicity and salinity unless extreme care is taken. Gypsum is a key ingredient for the maintenance of agriculture on many types of soil and over a wide pH range, including sodicity.Gypsum, in addition to prevention and correction of sodicity, includes: greater stability of soil organic matter, more stable soil aggregates, improved water penetration into soil, and more rapid seed emergence.Ida-Gro Pelletized Gypsum is clean, virtually dust free.
