3. Application
Fertilizer |
l Used as an effective P fertilizer for application through drip irrigation systems in field soil. |
l While ammonia volatilization from urea fertilizer reduces N fertilizer efficiency by crops, UP releases ammonia slowly due to that the chemical bonds clench the N content. |
|
l It is characteristic pH controller for improving the condition of calcareous soil white fertilization because of the low pH. |
|
l Added to blends which contain calcium nitrate and magnesium nitrate to produce water-soluble formulas such as 15-5-15, 13-2-20, and 13-2-13. The acidity of urea phosphate allows Ca, Mg and P to co-exist in solution. Under less acidic conditions, there would be precipitation of Ca-Mg phosphates. |
|
l Used in drip irrigation to clean the pipe system. |

7. Application Recommendations
Urea Phosphate 17-44-0 can be used in all fertirrigation schedules to supply totally assimilable nitrogen and phosphorus when the presence of potassium is not useful or required. To use put the powder in water and shake lightly: this immediately gives a clear and residue-free solution.
25-50kg/ hectare, repeating fertilization several times as necessary. It can be mixed with potassium nitrate to make an NPK solution as well as with other water-soluble fertilizers. Dosages very depending on the crop, the characteristics of the soil and the physiological condition of the plant.
