Ammonium sulphate contains ammoniacal nitrogen and water-soluble sulphur. The nitrogen is entirely in the form of ammonium, which reduces the risk of leaching during wet periods. This fertilizer is mainly used in arable farming and on grassland on crops that need a lot of sulphur (e.g. rapeseed and potatoes). In Southern Europe and outside Europe, ammonium sulphate is often used as a fertilizer for citrus fruits, coffee, rice, tea, bananas, pineapples, sugar beet and soya beans. It can be used as a single fertilizer or in blends.
