Use

Ammonia is the least expensive and most widely used nitrogen fertilizer. it is used in the manufacture of other fertilizers like urea, ammonium sulphate and ammonium chloride. ammonia is also used in the manufacture of nitric acid, hydrazine hydrate, urethane, acrylonitrile and sodium carbonate (solvay process). in addition, ammonia is used as a refrigerant, in nitriding of steels, in the petroleum industry, in the manufacture of explosives and rocket fuel, as a yeast nutrient, etc. anhydrous ammonia, which has great affity for water, contains approximately 82% nitrogen. this is the highest nitrogen content that any nitrogen fertilizer can have.
