The primary use of Ammonium Sulphate 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 Sulphate 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.

Ammonium Sulphate Crystal (Capro Grade) is a good nitrogen fertilizer is suitable for general soil and crops. It can make branches and leaves grow vigorously, improve fruit quality, and yield, and enhance crop resistance to disasters. It can be used as base fertilizer, topdressing fertilizer and seed fertilizer.

The primary use of ammonium sulphate 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. It can be used as straight fertilizer also can be used as water soluble fertilizer.

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.
