Gypsum Wikipedia. Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ܨH 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.
It's calcium sulfate and is used in a number of different applications. It has sulfur in the sulfate form, so it's all ready to be used by plants. The analysis shows it has 17% sulfur and 22% calcium. It is a little bit slower reacting for a sulfate than say ammonium sulfate or potassium sulfate, but the gypsum works to take out excessive sodium.
The difference between the two is that sulfate sulfur forms, such as gypsum or ammonium sulfate, contain readily available sulfur, while elemental sulfur must be oxidized to sulfate prior to plant uptake. However, elemental sulfur is not mobile in the soil and will not readily leach like sulfate forms.

Nov 01, 2015· Analysis of ammonium sulfate is also discussed in Chapter 5-2.2, by description of the Kjeldahl digestion method, by distillation or diffusion extraction and by conversion of ammonium salts (e.g. ammonium sulfate) into N 2 gas. Since ammonium sulfate was basically an inorganic compound, analysis of ammonium sulfate was included in this chapter.
At the Pira site with canola, there was a significant (p<0.05) yield response to both applied S as gypsum with or without urea (+44%), but no significant response to urea alone. However, when both N and S were supplied as ammonium sulfate, there was a larger (+75%) yield response.
Dry, powdered ammonium sulfate may be formed by spraying sulfuric acid into a reaction chamber filled with ammonia gas. The heat of reaction evaporates all water present in the system, forming a powdery salt. Approximately 6000M tons were produced in 1981. Ammonium sulfate also is manufactured from gypsum (CaSO 4 ·2H 2 O).
