DAP 18-46-0 (Diammonium Phosphate) is a high-concentration water-soluble nitrogen-phosphorus compound fertilizer, with fixed nutrient ratio of 18% total nitrogen (N), 46% available phosphorus (P₂O₅) and 0% potassium (K₂O). It appears as grayish-white or light yellow spherical granules, featuring high nutrient content, rapid dissolution and easy crop absorption. Suitable for all soil types and various crops in seedling and flowering stages, it supplies dual N-P nutrition, promotes root development and flower bud differentiation, and is a core base fertilizer for global agricultural production with stable quality and wide applicability.

Diammonium phosphate is widely used in agriculture. It is used as a nitrogen and phosphorus fertilizer to supply nitrogen and phosphorus nutrients required by crops, promote plant growth, improve yield and quality. In addition, diammonium hydrogen phosphate can also be used to control phosphorus deficiency in soil, and can improve soil texture and fertility.
