Ammonium sulphate is an inorganic salt with a number of commercial uses.
The primary use of ammonium sulphate is as a fertilizer for alkaline soil. It is quick release & fast acting, easily hygroscopic & caking. Normally it is used as seed fertilizer, base dressing & topdressing directly, particulaly suitable for soil lack of sulfur, low chlorine tolerance crops, sulfurphilic crops. It is also suitable for the rice seeding, the growth of tea, grass & vegetables.
The ammonium ion is released in the soil and forms a small amount of acid, which lowers the PH balance of the soil, contributes essential nitrogen for plant growth. The main disadvantage of using ammonium sulphate is its low nitrogen content. Longtime application of ammonium sulphate will cause soil acidfication.
Ammonium sulphate is also used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides. Therefore, it functions as bind iron and calcium cations that presented in both well water and plant cells. It is particularly effective as an adjuvant 2,4-D (amine), glyphosate, and glufosinate herbicides.
