Particulate Monoammonium Phosphate(Particulate MAP)

Short Description:

MAP has been an important granular fertilizer for many years. It’s water-soluble and dissolves rapidly in adequately moist soil. Upon dissolution, the two basic components of the fertilizer separate again to release ammonium (NH4+) and phosphate (H2PO4-), both of which plants rely on for healthy, sustained growth. The pH of the solution surrounding the granule is moderately acidic, making MAP an especially desirable fertilizer in neutral- and high-pH soils. Agronomic studies s...

    Agricultural Use

    MAP has been an important granular fertilizer for many years. It's water-soluble and dissolves rapidly in adequately moist soil. Upon dissolution, the two basic components of the fertilizer separate again to release ammonium (NH4+) and phosphate (H2PO4-), both of which plants rely on for healthy, sustained growth. The pH of the solution surrounding the granule is moderately acidic, making MAP an especially desirable fertilizer in neutral- and high-pH soils. Agronomic studies show that, under most conditions, no significant difference exists in P nutrition between various commercial P fertilizers under most conditions.

    Non-agricultural Uses

    MAP is used in dry chemical fire extinguishers commonly found in offices, schools and homes. The extinguisher spray disperses finely powdered MAP, which coats the fuel and rapidly smothers the flame. MAP is also known as ammonium phosphate monobasic and ammonium dihydrogen phosphate.
