Description
Monoammonium Phosphate (MAP) is a highly efficient source of phosphorus and nitrogen, specially formulated for early crop establishment. With a nutrient ratio of 11-52-0, MAP is a key component in starter fertilizers for cereals, legumes, fruits, and vegetables.
MAP has a low nitrogen content in ammonium form (NH₄⁺), which helps stabilize phosphorus in the root zone and minimizes leaching. Its high phosphorus concentration boosts seedling vigor, flowering, and early root expansion — critical for high-yield farming.
At Cavin Resource, we supply granular MAP produced under ISO-certified processes, ready for global shipment with full export documentation. Our MAP is compatible with most fertilizers and blends easily into NPK formulations. monoammonium phosphate bulk for sale
Reaction of Ammonia with Phosphoric Acid
-
MAP is manufactured by the direct reaction of ammonia (NH₃) with phosphoric acid (H₃PO₄).
-
The product crystallizes as (NH₄)H₂PO₄, forming free-flowing granules upon cooling.
-
The final fertilizer is low in heavy metals and has a neutral to slightly acidic pH.

1. What makes MAP better than DAP in some soils?
Answer:
MAP has a lower nitrogen content and an acidic pH, making it ideal for alkaline soils. DAP is more alkaline and may cause ammonium volatilization in high-pH conditions.
2. How should MAP be applied?
Answer:
Apply directly to the soil at planting or as a banded starter fertilizer. It can also be blended into dry NPK mixes or applied through fertigation in soluble form.
3. Is MAP safe for young seedlings?
Answer:
Yes. MAP’s low salt index makes it safer for direct root-zone applications, even for sensitive crops and young plants.
4. Does Cavin Resource ship internationally?
Answer:
Yes. We offer international logistics, documentation, SGS inspection, and custom packaging for global clients.
