Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite.

What Are the Benefits of Applying Gypsum to Soil?

The mineral gypsum is a byproduct of sulfide oxidation and is known as hydrous calcium sulfate or selenite Mined worldwide, gypsum is found in shale beds, according to the Mineral Information Institute Gypsum is an excellent source of calcium and is heavily used as an agricultural soil amendment.

University of Minnesota’s Mineral Pages: Gypsum

Gypsum is a very soft mineral that is easily identified by its hardness, cleavage, and solubility in water Typically clear to white, gypsum may be colored reddish to brown or yellow if impurities are present Most gypsum occurs in its massive form, as layers of rock that often intercalate layers of shale, limestone, or dolostone.

• Gypsum has no effect on soil fertility, structure, or pH of any other soil type • Most urban soils are not improved by additional gypsum • Before adding gypsum or any chemical to a landscape, have soil analysis performed to identify mineral deficiencies, toxicities, and soil character.

gypsum

Gypsum, common sulfate mineral of great commercial importance, composed of hydrated calcium sulfate It occurs in extensive beds associated with other evaporite minerals, particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite.

Gypsum vs Plaster

As nouns the difference between gypsum and plaster is that gypsum is a mineral consisting of the hydrated calcium sulphate when calcined, it forms plaster of paris while plaster is (uncountable) a paste applied to the skin for healing or cosmetic purpos As a verb plaster is to cover or coat something with plaster, or apply a plaster.

Gypsum plaster

Gypsum plaster, white cementing material made by partial or complete dehydration of the mineral gypsum, commonly with special retarders or hardeners added Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water For especially hard finish.

Anhydrite: The mineral anhydrite information and pictures

Anhydrite is not a common mineral, as it easily alters to the much more common mineral Gypsum from the addition of water into its chemical structureAnhydrite and Gypsum are chemically similar, except Gypsum has the addition of water In fact, the name of Anhydrite is derived from "An" and "Hydra"

Gypsum is a soft sulfate mineral composed of calcium sulfate with the chemical formula CaSO 4 2H 2 O This mineral forms as an evaporite mineral and as a hydration product of anhydrite, and serves as reference for the hardness value of 2 on the Mohs scale.

Garden Gypsum Information

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 regionsHowever, it doesn’t work in sandy soils and it can deposit an excess of calcium in regions where the mineral is already abundant Additionally, in areas with poor salinity, it pulls out too much sodium.
