Di Ammonium Phosphate (DAP) is a widely used agricultural fertilizer containing approximately 18% nitrogen and 46% phosphorus. This white to light gray crystalline fertilizer easily dissolves in soil, promoting rapid root and leaf growth, and enhancing crop yield.

Features and Applications

• Contains both nitrogen and phosphorus, enhancing root and leaf development
• Water-soluble and suitable for various fertilization methods
• Ideal for crops such as wheat, corn, rice, vegetables, and fruits
• Improves both quality and quantity of agricultural products

Technical Specifications

• Chemical Formula: (NH₄)₂HPO₄
• Physical Form: White to light gray crystalline solid
• Purity: ≥ 99%
• Nitrogen: 18%
• Phosphorus (P₂O₅): 46%
• Moisture: ≤ 0.5%

Safety and Precautions

• Direct contact with skin and eyes may cause irritation
• Avoid inhaling dust
• Store in a cool, dry place
• Keep away from alkaline and flammable substances

Packaging and Storage

• 50 kg durable bags
• Store in a dry, cool place
• Prevent moisture absorption and caking
• Keep away from acidic and alkaline fertilizers

Industrial Applications

• Fertilization in agriculture and horticulture
• Promotes root and leaf growth, enhancing crop yield
• Used in chemical industries for phosphate-based compounds

Di Ammonium Phosphate has been used as a fertilizer since the 1950s and significantly improved the yield of crops such as wheat and corn in industrialized countries.

Recent studies indicate that combining DAP with potassium fertilizers can enhance phosphorus uptake and improve crop efficiency. Research Source
