CAS NO.:7783-28-0
EINECS: 231-987-8
H.S.CODE: 31053000
Molecular formula:(NH4)2HPO4
Features:
This product is soluble in water, less solid after dissolution.
Use:
It is suitable for the demand of nitrogen and phosphorus elements in various crops, especially suitable for application in arid and rainless land; it has good miscibility with urea and ammonium nitrate, and is an ideal base fertilizer for producing multiple compound fertilizer and BB fertilizer. Concentrated application, or mixed application with farmyard manure, as far as possible to reduce the contact surface with the soil; deep application, increase the contact with the root system, so as to reduce the chemical fixation of phosphorus and improve the utilization rate of crop phosphorus fertilizer. Because the phosphorus content of diammonium phosphate is much higher than the nitrogen content, no matter it is used as base fertilizer, seed fertilizer or top dressing fertilizer, it is necessary to apply nitrogen fertilizer appropriately according to the rotation of soil fat and thin, crop varieties and growth conditions, so as to coordinate the ratio of nitrogen and phosphorus, improve its fertilizer efficiency and ensure crop growth. When making seed fertilizer, special attention should be paid not to contact with seeds directly. When making base fertilizer, the fertilization point should not be too close to the young root and bud to avoid burning by NH3 released from the molecule.
