Formula: (NH₄)₂HPO₄
Noms communs : DAP, Diammonium Phosphate Fertilizer
📌 Phosphate diammonique (DAP) is a high-quality, water-soluble inorganic phosphate widely used in agriculture, industrial applications, and, in limited cases, as a fermentation nutrient.
🌱 It provides essential nitrogen (N)etphosphorus (P₂O₅) to promote healthy root development, early growth, and higher crop yields.
⚙️ Industrial grades are used in fire retardants, water treatment, metal treatment, and catalysts.
