Description of Ammonium Sulphate

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. The product can be used as a single fertilizer or in blends. 

 

We supply two different ranges of ammonium sulphate: crystalline and granular. The difference is in the size of the granule. The crystalline range is the smallest type of granule, the products being AS-Crystal and AS-Standard.

The primary use of ammonium sulfate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.

 

It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There, it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate, and glufosinate herbicides.
