As global agriculture and industrial sectors continue to demand high-performance phosphate materials, Tongge has become a trusted supplier of Ammonium Dihydrogen Phosphate (MAP) for customers seeking reliable quality, excellent nutrient efficiency, and versatile industrial applications. Known for its high phosphorus content, water solubility, and stable chemical properties, MAP plays a vital role in modern crop nutrition, fire-retardant formulations, fermentation processes, and specialty chemical manufacturing. This article explores everything you need to know about MAP, including its composition, benefits, applications, specifications, and purchasing considerations.
Ammonium Dihydrogen Phosphate, commonly abbreviated as MAP, is an inorganic phosphate compound with the chemical formula NH₄H₂PO₄. It is a highly concentrated source of phosphorus and nitrogen widely used in agriculture, food processing, industrial manufacturing, and specialty chemical applications.
MAP is particularly valued because it dissolves rapidly in water, allowing plants to absorb nutrients efficiently. Its relatively low pH in the soil solution also helps improve phosphorus availability in alkaline soils.
The combination of nitrogen and phosphorus in a single product makes MAP one of the most cost-effective nutrient sources for modern farming operations.

The popularity of MAP comes from its unique combination of nutrient efficiency and operational flexibility.
These benefits make MAP a preferred phosphate source for growers aiming to maximize productivity while maintaining nutrient management efficiency.
Agriculture remains the largest consumer of MAP worldwide. Phosphorus is essential for energy transfer, root growth, flowering, and seed formation.
Because phosphorus availability is critical during the early growth stages, MAP is often applied at planting to ensure strong crop establishment.
Beyond agriculture, MAP serves numerous industrial markets due to its stable chemical composition and high purity.
In fire protection systems, MAP is widely recognized as a highly effective extinguishing component capable of interrupting combustion reactions.
