Monoammonium Phosphate Powder Map
-
≥300/ton
USD 600.00
Monoammonium Phosphate,can be used as a raw material for the production of compound fertilizer, and can also be used as a raw material for flame retardants in industry. Instructions for use: Monoammonium phosphate is suitable for all types of soil and crops, and can be used as base fertilizer, seed fertilizer and top dressing. Its usage, dosage and application principles are the same as those of diammonium phosphate.It should be noted that since monoammonium phosphate is acidic, it cannot be mixed with alkaline fertilizers when mixed with other fertilizers.
Monoammonium phosphate (fertilizer grade) is a powdery product and a good raw material for the production of BB fertilizer. It can be directly applied as a high-efficiency fertilizer, and can also be used as a nitrogen and phosphorus raw material for manufacturing a series of compound fertilizers. The product is widely used in rice planting, It is suitable for various food crops and cash crops such as wheat, corn, sorghum, cotton, fruits, vegetables, etc., and is suitable for use in arid and dry areas.

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.
An advantage of manufactured MAP is that lower-quality H₃PO₄ can be used compared with other P fertilizers often requiring a more pure grade of acid. The phosphorus pentoxide (P₂O₅) equivalent content of MAP varies from 48 to 61 percent, depending on the amount of impurity in the acid. The most common fertilizer composition is 11-52-0.
