Urea phosphate is a fertilizer having NPK formula 17-44-0. It is soluble in water, and produces a strongly acidic solution. Urea phosphate is sometimes added to blends which contain calcium nitrate, magnesium nitrate and potassium nitrate to produce water-soluble formulas such as 15-5-15 and 13-2-20. 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. Urea phosphate is often used in drip irrigation to clean pipe systems. * v * t * e

dbo:abstract
  • El fosfat d'urea, en anglès: Urea phosphate, és un compost orgànic compost per carboni, hidrogen, nitrogen, oxigen i fòsfor. La seva fórmula química és CO(NH₂)₂·H₃PO₄. Es fabrica fent reaccionar urea amb àcid fosfòric. De vegades es fa servir com a fertilitzant, principalment en la fertirrigació, la seva composició en elements NPK és 17-44-0. És soluble en aigua i produeix una dissolució fortament àcida. El fosfat d'urea de vegades es mescla amb nitrat de calci i nitrat de magnesi per produir formulacions solubles en aigua com 5-5-15, 13-2-20 i 13-2-13. L'acidesa del fosfat d'urea permet al calci, magnesi i fòsfor coexistir en la solució. Sota condicions menys àcides aquests elements precipitarien en forma de fosfats de calci i de magnesi. Sovint es fa servir el fosfat d'urea per netejar les canonades en els sistemes de reg gota a gota. És un producte corrossiu i la seva inhalació pot irritar les membranes mucoses i el tracte respiratori. (ca)

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. Urea phosphate is often used in drip irrigation to clean pipe systems. Chemically, the urea phosphate compound is made of an equimolar mix of urea and phosphoric acid crystallizing together, and freely disassociating when dissolving in water. It is available in fertilizer vendor bags that carry a UP signet on the packaging. * v * t * e (en)
