Ammonium sulfate is also produced from gypsum, which is calcium sulfate dihydrate (CaSO 4 • 2H 2 O), via the Haber process. This involves first converting natural gas (methane) into hydrogen, then reacting the hydrogen with nitrogen to produce ammonia, and finally, the ammonia is reacted with the gypsum to yield ammonium sulfate.

Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia. A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.
