Phosphate monoammonique (MAP 11-52-0) - Engrais de démarrage à haute teneur en phosphore

Monoammonium Phosphate (MAP) est un 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, et early root expansion — critical for high-yield farming.

Au Ressource Cavin, Nous fournissons 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

⚙️ Méthode de production

Réaction de l'ammoniac avec l'acide phosphorique

• MAP is manufactured by the direct reaction of ammonia (NH₃) avec acide phosphorique (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.

❓ Foire aux questions (FAQ)

1. What makes MAP better than DAP in some soils?

Réponse :
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?

Réponse :
Apply directly to the soil at planting or as a banded starter fertilizer. It can also be blended into dry NPK mixes ou applied through fertigation in soluble form.

3. Is MAP safe for young seedlings?

Réponse :
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?

Réponse :
Yes. We offer international logistics, documentation, SGS inspection, and custom packaging for global clients.
