Ammonium Sulfate is a widely used nitrogen fertilizer providing essential nitrogen (21%) and sulfur (24%) for crop growth. It plays a dual role: enhancing nitrogen availability in alkaline soils and improving sulfur content for oilseed and protein-rich crops. Its quick solubility, low volatility, and acidifying effect on soil pH make it ideal for cereals, vegetables, fruits, and plantation crops. It is also used in some industrial applications like flame retardants and protein precipitation in biotech.
