Introduction
Ammonium sulphate, (NH4)2SO4, is an inorganic chemical compound commonly used as a fertiliser. It is used largely as an artificial fertiliser for alkaline soils. In the soil the sulphate ion is released and forms bisulphate, lowering the pH balance of the soil and contributing essential nitrogen for plant growth.
Ammonium sulphate is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate, and glufosinate herbicides.
Ammonium sulphate is also used in the preparation of other ammonium salts. In biochemistry, ammonium sulphate precipitation is a common method for purifying proteins by precipitation. As such, ammonium sulphate is also listed as an ingredient for many United States vaccines per the Center for Disease Control.
Ammonium sulphate is also a food additive.
