Diammonium phosphate (DAP) is a mainstream high-concentration nitrogen-phosphorus binary compound fertilizer in agriculture. It is an essential basic fertilizer for planting and a core raw material for compound fertilizer processing. It is often used in conjunction with NPK fertilizer granulator machines to complete the compound fertilizer formulation production. This fertilizer is rich in nutrients, has stable effects, and is widely adaptable, making it a core base fertilizer for field crops and fruit and vegetable cultivation.

DAP is a chemically neutral and physiologically alkaline fertilizer. Standard nutrient content includes 18% nitrogen, 46% phosphorus pentoxide, and a total nutrient content of 64%. The finished product is a grayish-white granule with excellent water solubility and is not prone to clumping. Its material characteristics are suitable for large-scale wet granulation processing using rotary drum granulators, making it easily absorbed by soil and crops, and convenient for storage and transportation.

It mainly supplements crops with nitrogen and phosphorus nutrients. Phosphorus promotes root growth and enhances crop resistance to drought, cold, and lodging; nitrogen helps seedling development, improves stunted seedlings, weak seedlings, and poor root development, and promotes robust plant growth.

This fertilizer is suitable for grain crops such as wheat, corn, and rice, as well as cash crops such as melons, fruits, and fruit trees. It is especially suitable for phosphorus-deficient soils and is mostly used as a base fertilizer, with a long-lasting effect.

When using it, it is important to note that DAP should not be mixed with alkaline fertilizers such as wood ash or quicklime to avoid phosphorus degradation. Long-term single application is also not recommended; it should be combined with potassium fertilizer and micronutrients for balanced fertilization. Its stable properties also make it suitable for dry molding processing using double roller press granulators. Overall, diammonium phosphate (DAP) offers high cost-effectiveness and strong practicality, making it a high-quality base fertilizer for improving quality and increasing yield in modern agriculture.
