1. What It Is:
MAP (Monoammonium Phosphate) is a granular, water-soluble fertilizer that provides both nitrogen (N) and phosphorus (P)—two essential macronutrients for plant growth. It’s especially effective during early crop development.
2. Chemical Properties:
- Chemical Formula: NH₄H₂PO₄
- Nutrient Content:
- Nitrogen (N): ~11%
- Phosphorus (P₂O₅): ~52%
- Form: Dry, free-flowing granules
- Color: Gray to off-white
3. Applications:
Agriculture:
- Used as a starter fertilizer for cereals, vegetables, fruits, oilseeds, etc.
- Encourages strong root growth and flowering
- Ideal for banding near seeds due to low ammonia release
Fertilizer Blends: Often included in NPK blends
4. Advantages:
- High phosphorus availability for early-stage crops
- Less hygroscopic (absorbs less moisture) – good for storage
- Low pH effect helps in alkaline soils
- Can be used in dry or liquid formulations
5. Packaging & Storage:
- Available in bulk, 50 kg bags, or jumbo bags
- Store in a cool, dry place to avoid caking
- Avoid mixing with alkaline materials
