Di-Ammonium Phosphate (DAP)

Di-Ammonium Phosphate (DAP) with 18-46-0 analysis is the world’s most widely used phosphorus fertilizer — the cornerstone of crop nutrition programs on every inhabited continent. DAP provides the highest phosphorus concentration of any compound NP fertilizer, delivering 46% P₂O₅ plus 18% nitrogen in a highly water-soluble, granular form. As a critical import commodity for India, Pakistan, Bangladesh, Brazil, Ethiopia, and 50+ countries, DAP is the foundation of global food security. Dongkwang Poland supplies technical and fertilizer grade DAP to importers, blending plants, and distributors worldwide.

DAP dissolves rapidly in soil moisture, releasing ammonium (NH₄⁺) and phosphate (HPO₄²⁻) ions. The ammonium component creates a temporary alkaline microsite around each granule (pH 8.0-8.5) that enhances phosphorus solubility in the first 24-48 hours — a unique advantage over other phosphate sources. The high P₂O₅ concentration (46%) means less product is needed per hectare to meet phosphorus targets. Water-soluble P₂O₅ (≥90%) ensures rapid availability for root uptake during the critical establishment phase. The nitrogen component (18%) provides supplemental N for early vegetative growth.

Ideal For

Store in dry, covered conditions. DAP is less hygroscopic than urea but should be protected from moisture. Shelf life: 24 months. Compatible with standard spreading and blending equipment. The alkaline reaction can release ammonia odour from freshly opened bags — store in ventilated areas. Avoid mixing with lime in storage.
