Products Introduction
DAP Diammonium Phosphate Granulars are a high-concentration, fast-acting compound fertilizer containing 18% nitrogen (N) and 46% phosphorus pentoxide (P₂O₅). They appear as off-white or light brown granules.
Products Advantages
High nutrient ratio: The N+P₂O₅ content of the diammonium phosphate granules is as high as 64%, with high fertilization efficiency and reduced input costs.
Rapid dissolution and absorption: The diammonium phosphate granules have a high water-soluble phosphorus content, which can be quickly absorbed by crops and promote early root development.
Strong soil adaptability: The diammonium phosphate granules are neutral to weakly alkaline, suitable for acidic soils, and help adjust soil pH.
Uniform particles without compaction: The diammonium phosphate granules have good fluidity and are suitable for mechanical spreading in the field to improve fertilization efficiency.
Main application crops
Food crops: wheat, corn, rice
Economic crops: vegetables, cotton, fruit trees, oil crops, etc.
Can be used for gardening, lawn management, etc.
Usage and recommended dosage
Usage method:
Base application: spread before sowing and then till and mix
Strip application/hole application: apply on both sides of the crop root system to avoid contact with seeds
Mixed fertilization: can be mixed with potassium fertilizer and trace element fertilizer, with reasonable ratio
Recommended dosage (per mu):
General crops: 25~35kg
Crops with high phosphorus requirements: 40~50kg
Fruit trees: 0.5~2kg/plant, depending on tree age and soil conditions
