Mono Ammonium Phosphate (MAP) 12/61

Monoammonium phosphate (MAP) is a widely used source of P and N. It is made of two constituents common in the fertilizer industry and has the highest P content of any common solid fertilizer.

The process for manufacturing MAP is relatively simple. In a common method, a one to one ratio of ammonia (NH3) and
phosphoric acid (H3PO4) is reacted and the resulting slurry of MAP is solidified in a granulator. The second method is to introduce
the two starting materials in a pipe-cross reactor where the reaction generates heat to evaporate water and solidify MAP.
Variations of these methods are also in use for MAP production. An advantage of producing MAP is that lower quality H3PO4
can be used compared with other P fertilizers that often require a more pure grade of acid. The P2O5 equivalent content of MAP
varies from 48 to 61%, depending on the amount of impurity in the acid.

MAP ((NH4H2PO4)  is a highly concentrated granulated nitrogen-phosphoric fertilizer, where nitrogen is represented in ammonia form. Produced via the neutralizing of phosphoric acid with ammonia. Monoammonium phosphate is used for all soil types, for ground and bed application, and for all agricultural crops and climates. Any grade of compound fertilizers can be produced with Monoammonium phosphate as input. This product is non-hygroscopic, non-dust forming and non-caking, constant granulometric composition, and water-soluble.
