Diammonium Phosphate (DAP) 18-46-0 Fertilizer

Diammonium Phosphate (DAP) 18-46-0 is a highly efficient, water-soluble compound fertilizer widely used in modern agriculture to provide crops with essential nitrogen (N) and phosphorus (P). With a nutrient composition of 18% nitrogen (N) and 46% available phosphorus expressed as P₂O₅, DAP fertilizer supports vigorous early-stage plant development, strong root establishment, and improved crop growth.

DAP 18-46-0 is suitable for a wide range of agricultural applications, particularly for wheat, barley, cereals, vegetables, and other phosphorus- and nitrogen-demanding crops. Its excellent solubility enables nutrients to become readily available to plants following application.

Key Benefits of DAP 18-46-0 Fertilizer

1. High Water Solubility for Rapid Nutrient Availability
DAP fertilizer has excellent water solubility, allowing nitrogen and phosphorus nutrients to dissolve quickly and become accessible to plant roots. This makes it an effective fertilizer for supporting crop nutrition during critical growth stages.

2. Excellent Source of Nitrogen and Phosphorus
DAP 18-46-0 delivers a balanced combination of two major plant nutrients. The 18% nitrogen content helps support early vegetative growth, while 46% P₂O₅ promotes strong root development, energy metabolism, and overall plant establishment.

3. Supports Early Crop Development
Because phosphorus is particularly important during the early stages of plant growth, DAP is commonly applied as a starter or basal fertilizer. Its nitrogen content further supports initial crop development and helps meet the nutritional requirements of young plants.

4. Efficient Phosphorus Fertilization
When DAP dissolves in moist soil, localized changes in soil chemistry occur around the fertilizer granule, helping create conditions that support phosphorus availability in the rhizosphere. Proper placement and soil management can improve nutrient-use efficiency.

5. Widely Used Phosphate Fertilizer
Diammonium phosphate is one of the most widely used phosphorus fertilizers worldwide. Its high nutrient concentration, good handling characteristics, and favorable physical properties make it a preferred choice for agricultural fertilizer programs.
