LIQUID NITROGEN FERTILIZERS (UAN)
UAN a water solution of urea and ammonium nitrate.
Application
UAN contains amide N of urea, ammoniacal and nitric N of ammonium nitrate. Applied to soil nitrogen is easily and efficiently assimilated by plants in case of urgent need of extra fertilizing. UAN solutions can be used for formulation of double and triple fertilizer solutions.
Subject to N content resulting in change of crystallization temperature and consequently, in application for different climatic conditions UAN is available in 3 grades: UAN 28, UAN 30 and UAN 32.
To reduce corrosion ability of UAN corrosion inhibitor is added.
