(NH4) 2so4 N 21%, Granular/Crystal Ammonium Sulphate Application:

Ammonium Sulphate is mostly used as nitrogen fertilizer, it provides an equal balance of nitrogen and sulphur, meets short term sulphur deficits of crops, pastures and other plants.Fast release, quick acting
More efficiency than urea, ammonium bicarbonate, ammonium chloride,  
Can be readily blended with other fertilisers. It has the desirable agronomic features of being a source of both nitrogen and sulphur.
Ammonium sulphate can make crops thrive and improve fruit quality and yield and strengthen resistance to disaster,can be used for common soil and plant in basic fertilizer, additional fertilizer and seed manure.

Suitable for the rice seedling, paddy fields, wheat and grain, corns or maize, the growth of tea, vegetables, fruit trees, hay grass, lawns, turf and other plants. 

Ammonium sulfate has also been used in flame retardant compositions acting much like diammonium phosphate.
As a flame retardant, it lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char.
