Uses of ammonia. The major use of ammonia is as a fertilizer. It is most commonly applied directly to the soil from tanks containing the liquefied gas. The ammonia can be applied directly or in the form of ammonium salts, such as ammonium nitrate, NH4NO3, ammonium sulfate, (NH4)2SO4, and various ammonium phosphates. Urea, (H2N)2C=O, is also used as a source of nitrogen for fertilizer. Ammonia is also used in the manufacture of commercial explosives (e.g., trinitrotoluene [TNT], nitroglycerin, and nitrocellulose). In the textile industry, ammonia is used in the manufacture of synthetic fibres, such as nylon and rayon.
