Ammonium phosphate monobasic is widely used in agriculture as a highly effective fertilizer, providing essential nitrogen and phosphorus to promote healthy plant growth and improve crop yields. It is particularly beneficial in acidic soils, as it helps to neutralize soil pH while supplying vital nutrients. In the food industry, it serves as a leavening agent in baked goods, aiding in dough expansion and texture improvement. Additionally, it is utilized in fire extinguishers as a flame retardant, where it helps to suppress flames by releasing ammonia and forming a protective layer. In water treatment, it acts as a corrosion inhibitor, protecting metal surfaces in industrial systems. Its versatility also extends to laboratory settings, where it is used as a buffering agent to maintain stable pH levels in various chemical processes.
