Briefing
Monoammonium Phosphate (MAP 12-61-0) wholesale supplier offers bulk, high-purity fertilizer for agriculture. OEM & ODM services available.
Detailed
What is Monoammonium Phosphate (MAP)?
Monoammonium Phosphate (MAP), also known as MAP 12-61-0, is a high-efficiency water-soluble phosphate fertilizer containing nitrogen (N) and phosphorus (P₂O₅).
With a typical nutrient ratio of 12% Nitrogen (N) and 61% Phosphorus Pentoxide (P₂O₅), MAP provides a highly concentrated source of phosphorus for agricultural production. It is widely used in basal fertilization, fertigation systems, compound fertilizer production, and specialty fertilizer formulations.
MAP chemical formula is NH₄H₂PO₄, which dissolves rapidly in water and releases ammonium nitrogen and phosphate ions, providing essential nutrients for early root development, flowering, and crop establishment.
Due to its excellent water solubility, low salt index, and acidic reaction characteristics, MAP is especially suitable for alkaline soils and modern precision agriculture systems.
Core Features & Competitive Advantages
·High Phosphorus Concentration & Nutrient Efficiency
High Phosphorus Content
MAP provides approximately 61% P₂O₅, making it one of the most concentrated phosphate fertilizers available for agricultural applications.
High phosphorus concentration helps reduce transportation costs and application volume compared with lower-grade phosphate fertilizers.
Benefits:
· Efficient phosphorus delivery
· Reduced fertilizer handling cost
· Suitable for intensive farming systems
· Ideal raw material for compound fertilizers
·Balanced Nitrogen & Phosphorus Supply
Unlike single nutrient phosphate fertilizers, MAP supplies both nitrogen and phosphorus.
The ammonium nitrogen provides continuous nitrogen nutrition, while phosphate supports:
· Root development
· Energy transfer
· Crop establishment
· Early plant growth
Stability & Functionality
Monoammonium Phosphate has excellent chemical stability under normal storage conditions.
Its acidic solution characteristic helps improve phosphorus availability in alkaline soils.
Key functions:
· Stable during transportation
· Easy blending with other fertilizer materials
· Suitable for NPK fertilizer production
· Compatible with most fertilizer formulations
