Answer 1

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 introduces the two starting materials in a pipe-cross reactor, where the reaction generates heat to evaporate water and solidify MAP. Other methods exist as well. An advantage of manufactured MAP is that lower-quality H3PO4 can be used compared with other P fertilizers often requiring a more pure grade of acid. The phosphorus pentoxide (P2O5) equivalent content of MAP varies from 48 to 61 percent, depending on the amount of impurity in the acid.
