Diammonium Phosphate (DAP): The Global Standard for High-Analysis Phosphorus
Diammonium Phosphate (DAP 18-46-0) is the world’s most widely used phosphorus fertilizer, engineered for maximum nutrient delivery and superior crop establishment. By combining 18% Ammoniacal Nitrogen with 46% Phosphorus Pentoxide (P2O5), DAP provides a highly concentrated, fully water-soluble solution that powers root development and ensures vigorous early-stage plant growth.
1. Technical Specification (TDS)
Our DAP is manufactured via a precise reaction of phosphoric acid and ammonia, resulting in a consistent, hard-granular product that exceeds international quality benchmarks.
| Parameter | Specification (Grade 18-46-0) |
| Total Nutrients (N+P2O5) | 64.0% |
| Total Nitrogen (N) | 18.0% |
| Available Phosphorus (P2O5) | 46.0% |
| Water-Soluble P within P2O5 | 90% of available P |
| Moisture (H2O) | 1.5% |
| Granulometry (2.0–4.0mm) | 90% |
| Appearance | Dark Brown, Gray, or Yellow Granules |
2. Strategic Advantages for the End Buyer
-
Optimized Starter Effect: The ammoniacal nitrogen in DAP lowers the soil pH in the immediate vicinity of the granule, which significantly enhances the uptake of phosphorus by young roots—a critical advantage in cold or alkaline soils.
-
Superior Solubility: With over 90% of its phosphorus being water-soluble, DAP provides an immediate nutrient boost, ensuring crops have the energy required for rapid cell division and root expansion.
-
Logistical Cost-Efficiency: Due to its ultra-high nutrient concentration ($64\%$ total active units), DAP offers the lowest transportation, storage, and application costs per unit of phosphorus compared to lower-grade alternatives.
-
Physical Integrity: Our granules are steam-granulated and treated with specialized anti-caking agents, ensuring high crushing strength and dust-free handling for mechanized bulk blending and precision air-seeding.
3. Primary Applications
-
Broad-Acre Farming: Essential for cereals (wheat, barley), oilseeds (canola, soybeans), and corn.
-
Basal Fertilization: Ideally applied during seeding or tilling to place phosphorus directly in the root zone.
-
Professional Blending: The perfect base component for high-quality NPK bulk blends.
4. Quality Assurance & Export Capacity
-
Global Compliance: Produced in accordance with ISO 9001 standards and compliant with international maritime fertilizer shipping codes.
Inspection: We support third-party inspections (SGS/CCIC) at the port of loading to verify nutrient content and granulometry.
-
Packaging: Heavy-duty 50kg PE/PP bags or in 9.5kg bags with UV protection.
