Urea Phosphate 17-44-0
is a NP water-soluble fertilizer with acid reaction for fertirrigation with a high percentage of nitrogen and phosphorus. It features a high degree of purity and solubility; the acid reaction favors absorption of N and P as well as the other nutritive elements present in the soil or added to the mixture. Nitrogen is present in the form of urea and phosphorus is totally water-soluble. This product, when used with hard water, prevents formation of scale and clogging in fertirrigation systems. The phosphorus contained is an excellent starter for crops, favoring root growth and rapid spring leafage by orchard crops.

2. A pplication
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.
