Molecular Formula: (NH4)2HPO4
DAP also known as diammonium hydrogen phosphate (DAP), is a compound fertilizer
of two kinds of nutrients including nitrogen and phosphorus. Yellow or dark gray particles,
soluble in water, insoluble in ethanol.Has a certain moisture absorption, easy decomposition in the humid air, volatile ammonia become diammonium hydrogen phosphate. The aqueous solution was weakly alkaline, pH8.0.
|Yellow or brown Granular
|Total P2O5 + N
1.Diammonium phosphate is a high concentration of quick acting fertilizer for any crop and soil, especially in hi nitrogen phosphorus requirement of crops, Can be used as base fertilizer or additional fertilizer , should be deeply in soil.
2.With urea, ammonium nitrate, ammonium chloride can be mixed with good, because itself does not contain potassium, should combined application with potash (potassium chloride, potassium sulfate) .
- As physical neutral fertilizer, applied to most crops and soil. To ensure the application
of safety, crop seeds to keep a distance of 5-10 cm is the best , Early and deep using for crops.
