Ammonium Sulphate

Ammonium Sulphate provides the plant with nitrogen and sulphur at the same time which enables the plant to maximize growth rate and yield

Product Description

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.


Direct application or in NPK blends. 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.
