Benefits

l     MAP is an efficient source of phosphorus.

l     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.

 

Application

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.

 

Compatibility

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.
