Used primarily as a nitrogen-sulfur fertilizer in agriculture, providing essential nutrients for crop growth, especially in sulfur-deficient soils. Commonly applied to rice, corn, wheat, and fruits, it enhances protein synthesis and chlorophyll production. Also utilized in water treatment to remove ammonia and as a precipitating agent in protein purification during biochemical processes. In industrial settings, it serves as a flame retardant and in the production of ammonium salts. Its high solubility makes it suitable for foliar feeding and fertigation systems.
