China Mono Ammonium Phosphate (MAP) 12-61-0 Fertilizer Suppliers and Factory for Enhanced Crop Production
Product Overview
Mono Ammonium Phosphate (MAP) is a high-purity phosphorus fertilizer designed to deliver readily available phosphorus and ammonium nitrogen to crops during critical growth stages.
Mono Ammonium Phosphate (MAP) fertilizer contains a high proportion of phosphorus in a soluble form that plants can easily absorb. This makes it particularly effective during the early growth period, when strong root development and vigorous plant establishment are essential.
With excellent water solubility and stable chemical properties, MAP fertilizer performs well in fertigation systems, drip irrigation programs, and foliar nutrient applications. The ammonium nitrogen component also contributes to high phosphorus availability in the root zone by slightly lowering the local pH around plant roots.
MAP fertilizer is widely used in field crops, vegetables, fruits, greenhouse crops, and plantation agriculture. It can also be used as a key raw material in compound fertilizers, liquid fertilizers, and customized nutrient blends.

Application Scenarios
MAP fertilizer is suitable for a wide range of agricultural fertilization systems.
Fertigation & Drip Irrigation
Due to its high solubility, MAP fertilizer is widely used in fertigation and drip irrigation systems. It dissolves rapidly in water and delivers phosphorus efficiently to the plant root zone.
Benefits include:
- Rapid nutrient availability
- Uniform nutrient distribution
- Improved phosphorus efficiency
Foliar Application
MAP fertilizer can also be applied through foliar spraying when crops require rapid phosphorus supplementation.
Foliar feeding with MAP supports:
- Faster plant response to phosphorus deficiency
- Enhanced root growth and plant vigor
- Improved crop development during early stages
Fertilizer Blending & Industrial Use
MAP fertilizer is frequently used as a component in:
- Compound fertilizer production
- Liquid fertilizer formulations
- Custom nutrient blends
Packaging Options
- 25kg standard bags
- Customized packaging available upon request
- OEM and private label packaging supported
Product Positioning
