Sulphate of Ammonia
Sulphate of ammonia is sometimes known as ammonium sulphate or ammonium sulfate
is an inorganic compound used as a fertiliser to supply nitrogen to plants. For
those who enjoy chemistry it's chemical symbol is (NH4)2SO4.
It is made by a commercial process that causes ammonia to react with suphuric
acid. When added to water it becomes soluble and thus is readily taken up by the
plants, with effects being noticed in under 10 days.
Since it is highly soluble in water it also means that it it leeches from the
soil easily, thus requiring regular applications.
