Di-Ammonium Phosphate (DAP)
Di-Ammonium Phosphate (DAP)
Chemical Formula: (NH₄)₂HPO₄
HS Code: 31053000
Product Overview
Di-Ammonium Phosphate (DAP) is the most widely used phosphatic fertilizer in agriculture, combining 18% Nitrogen (N) and 46% Phosphorus Pentoxide (P₂O₅). Its balanced nutrient composition and excellent solubility make it ideal for all soil types and crops, providing both immediate and sustained nutrient availability.
DAP is favored as a basal fertilizer because it supports robust root development, vigorous vegetative growth, and early flowering, ensuring higher yields and improved crop quality.
Key Benefits:
- Provides an ideal NP ratio (1:2.5) for early plant development.
- Highly water-soluble and easily absorbed by plants.
- Encourages root establishment and seedling vigor.
- Compatible with most fertilizers and soil conditioners.
- Excellent physical properties for easy handling and uniform spreading.
