1. What It Is:
DAP (Di-Ammonium Phosphate) is a widely used phosphate fertilizer containing two essential nutrients: nitrogen (N) and phosphorus (P). It is known for its high nutrient content and excellent crop response.
2. Chemical Properties:
- Chemical Formula: (NH₄)₂HPO₄
- Nutrient Content:
- Nitrogen (N): ~18%
- Phosphorus (P₂O₅): ~46%
- Form: Dry, free-flowing, granular or crystalline
- Color: Grey, brown, or beige granules
3. Applications:
Agriculture:
- Used at planting stage for crops like wheat, corn, rice, vegetables, etc.
- Promotes strong root development and early growth
- Suitable for all soil types
Industrial Use:
- Flame retardants, metal finishing, yeast production
4. Advantages:
- Highly concentrated source of N and P
- Low salt index, safe for early seedling growth
- Easy to apply, mix, and store
- Quick-release nutrients, ensuring fast plant uptake
5. Packaging & Storage:
- Typically packed in 50 kg bags, jumbo bags, or bulk
- Store in cool, dry places to prevent caking or moisture absorption
