Ammonium Sulphate

Ammonium sulphate provides the plant with nitrogen and sulphur at the same time, and due to that enables the plant to have a very high growth and yield.


Ammonium sulphate (AS) is a granular or crystalline, in general white nitrogen fertilizer, containing 21,0% nitrogen and 24,0% sulphur. Because AS contains 100% ammonium nitrogen it guarantees a long-term and sustainable nitrogen supply. Furthermore it prevents the nitrogen from being washed out of the soil. In addition, AS supports the availability of secondary nutrients like manganese, iron, and boron in the soil. AS is generated as a by-product from the caprolactam production. Western Europe represents the biggest production region worldwide.

Examples of applications

Ammonium sulphate is a nitrogen fertilizer which is being used either for fertilizer blending operations or for the direct application by the farmer. HELM is actively marketing different grades and qualities of AS from varying origins in order to provide its customers the best possible product selection through a wide-ranging distribution network around the world.
