Monoammonium phosphate (MAP) is one of the most widely used starter fertilizers in modern agriculture. It is commonly employed to supply nitrogen and phosphorus at the time of planting, supporting rapid root establishment and early crop growth. Additionally, it serves as the primary active ingredient in ABC dry chemical fire extinguisher powder, where it forms a barrier that smothers and interrupts combustion when heated. MAP is also utilized as a food additive for leavening and pH buffering in baked goods. Furthermore, it finds applications in specialty blended fertilizer manufacturing requiring a high-analysis, water-soluble phosphate source.
