Mono Ammonium Phosphate Acronyms – Ammonium phosphate, MAP Chemical Formula: NH4H2PO4 Agricultural application - Mono Ammonium Phosphate as fertilizer mainly catagorized into two types. Fertilizer for soil application and fertilizer for drip or foliar application(fertigation).MAP for fertigation-By process of manufacturing there 2 types of MAP available. MAP hot process & MAP wet process. Hot process MAP is usually very pure becuase the process itself yeilds very high purity. Hot process MAP can be identified easily with naked eye by its fine shiny crystals. Its purity is about 99.5%.Wet process MAP is has to be lower in purity because of teh limitation in manufacturing process. Purity of out of this process is about 97-98.5% at the most. Wet process MAP is gainning popularity in agriculture because of its slight price advantage over hot process. Majority of MAP traded into india are wet proces MAP. Customer and enduser can not distinguish a MAP quality due to lack of knowledge and therefore wet is sold on price advantage. Only we are still maintaining its standard by supply hot process MAP. |
