Product Description

Ammonium Sulphate (Ammonium Sulfate/AS/SOA) is most common use & typical inorganic nitrogen fertilizer.Fast release & quick acting. 

Ammonium Sulfate Granular is made by extrusion granulation process and dyed by hi-temperature steam and electric furnace,so it is hardness and anti-caking

The primary use of ammonium sulphate granular is as a fertilizer for alkaline soil. Quick release &  fast acting. Easy hygroscopic in air and unti-caking. Used as seed fertilizer, base dressing & topdressing directly. Particularly suitable for soil lack of sulfur, low chlorine tolerance crops, sulfurphilic crops. Suitable for the rice seedling, the growth of tea, grass & vegetables.

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 sulphate is its low nitrogen content. Long-time application by ammonium sulphate will cause soil acidification.
