Insoluble matters in water
1. It is an efficient source of phosphorus.
2. It facilitates plant uptake of the phosphorus naturally present in the soil. This is due to the ammonium (NH4+) in MAP, which lowers the pH in the root zone and thus enhances phosphorus availability.
Fertigation: Because of unique product characteristics, MAP can be applied through any irrigation system and on any growing medium. Unlike phosphoric acid, MAP is moderately acidic Therefore; it is not corrosive to fertilizer pumps or to irrigation equipment.
MAP is compatible with most water-soluble fertilizers, except for fertilizers containing calcium (Ca++) or magnesium (Mg++). To apply MAP in combination with calcium or magnesium fertilizers, use two fertilizer tanks. If only a single fertilizer tank is available, apply those fertilizers at different times.

-Soil application with drip irrigation: 15-20 kg/Hectare (Apply every 3days.
Total application times: 24/2 months)
Stored at a cool, dry and well ventilated place.
