Ammonium sulfate is a mixed fertilizer which contains nitrogen and sulfur nutrients (FAO, 2003, Tisdale, 2002). The ammonium sulfate provides the ideal solution that has a quick sulfate release tied in with the seasonlong availability of degradable sulfur (Hoeft et al., 1985, Dudal, 2002).
There are 1,100 gypsum fertilizer suppliers, mainly located in Asia. The top supplying countries or regions are China, India, and Pakistan, which supply 96%, 1%, and 1% of gypsum fertilizer respectively. Gypsum fertilizer products are most popular in Domestic Market, Africa, and South America.

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).
Gypsum . Our Gypsum range of products is suitable for all agricultural, horticultural and amenity applications for soil treatment as a conditioner, fertiliser and for correctional purposes. All products are high quality soluble Calcium Sulphate varying in presentation; therefore suitable for all applications. Ammonium Sulphate
Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia. A highmelting (decomposes above 280 ) white solid which is very soluble in water ( g/100 g water at 0 ; g/100 g water at 100 ), it is widely used as a fertilizer for alkaline soils.
Gypsum is a byproduct available from Phosphoric Acid Plant and used in production of Ammonium Sulphate. GSFC has been first in the country to develop and implement successfully PhosphoGypsum process for manufacture of Ammonium Sulphate.
