Chinese Professional Kno2 Kno3 - Technical Monoammonium Phosphate – Prosperousagro

Monoammonium phosphate (MAP) is a widely used source of phosphorus (P) and nitrogen (N). It’s made of two constituents common in the fertilizer industry and contains the most phosphorus of any common solid fertilizer.

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.

According to the production process, monoammonium phosphate can be divided into wet monoammonium phosphate and thermal monoammonium phosphate; It can be divided into monoammonium phosphate for compound fertilizer, monoammonium phosphate for fire extinguishing agent, monoammonium phosphate for fire prevention, monoammonium phosphate for medicinal use, etc; According to the component content (calculated by NH4H2PO4), it can be divided into 98% (Grade 98) monoammonium industrial phosphate and 99% (Grade 99) monoammonium industrial phosphate.

It is white powdery or granular (granular products have high particle compressive strength), easily soluble in water, slightly soluble in alcohol and insoluble in acetone, the aqueous solution is neutral, stable at room temperature, no redox, will not burn and explode in case of high temperature, acid-base and redox substances, has good solubility in water and acid, and the powdered products have certain moisture absorption, At the same time, it has good thermal stability, and will be dehydrated into viscous chain compounds such as ammonium pyrophosphate, ammonium polyphosphate and ammonium metaphosphate at high temperature.
