Differences Between Gypsum And Lime - No-Till Farmer
Gypsum, on the other hand, is CaSO4.H2O. It can occur in many forms — selenite is the crystal form, while alabaster is powdery. Most commonly used in Kansas to remediate sodic soils, a ton of gypsum contains about 320 pounds of sulfur. Unlike lime, it does not affect soil pH — elemental sulfur is the correct form for reducing pH.

Gypsum and Lime - Calcium Sulfate Soil Amendment ...
Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 0). Flue gas desulfurization (FGD) gypsum, such as GYPSOIL ® brand gypsum, is a co-product material derived from the scrubbing of flue gas emissions in coal-burning power plants. Gypsum can be spread with lime and litter spreaders. Gypsum is not acid soluble and will not change the soil pH.

Flue-gas desulfurization - Wikipedia
This makes it harder on the equipment. A spray tower is typically used for this application. The use of lime results in a slurry of calcium sulfite (CaSO 3) that must be disposed of. Fortunately, calcium sulfite can be oxidized to produce by-product gypsum (CaSO 4 · 2H 2 O) which is marketable for use in the building products industry.

gypsum - Michigan State University
Gypsum deposits lie in flat beds of about six to eight feet in thickness, and are often inter-layered with limestone or shale. Gypsum deposits were formed millions of years ago when salt water oceans covered most of the earth, and as they receded, may inland "dead" seas were formed which, as evaporation continued, became more and more salty.
