Ammonia is a colorless alkaline gas. It is formed in the body during decomposition of organic materials during a large number of metabolically important reactions. Note that the aqueous form of ammonia is referred to as ammonium hydroxide.
Ammonia can be applied directly or in the form of ammonium salts, such as ammonium nitrate, NH 4NO 3, ammonium sulfate, (NH 4) 2SO 4, and various ammonium phosphates. Urea, (H 2N) 2C=O, is also used as a source of nitrogen for fertilizer.
