N-content in ammonium sulphate is about 20.60%. This is an inorganic salt most commonly used as soil fertilizer and it contains 20.60% of nitrogen and 24% Sulphur. 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.
