  • Gypsum and its role in trapping ammonia gas

    Gypsum and its role in trapping ammonia gas

    Aug 01, 2014 · Gypsum has more sulfate available so it can trap more ammonium than superphosphate. The more product blended in the soil, the more ammonia was trapped. The key is to predict the amount of nitrogen per ton of material that will volatilize and then apply enough gypsum to capture that ammonia into a stable ammonium sulfate .

    Calcium sulfate - Wikipedia

    Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates.In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant.One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.It has many uses in industry. All forms are white solids that are poorly soluble in water.
