UAN-32 is a liquid nitrogen source supplied in 1000L IBCs. UAN-32 contains nitrogen in urea, ammonium and nitric forms. When applied it is taken up both through the plants leaf and root system. UAN-32 can significantly improve nitrogen responses as ammonium and nitric nitrogen can be directly taken up by plants, unlike urea nitrogen which must first go through hydrolysis which is the process when urea nitrogen is broken down to ammonium nitrogen by soil enzymes.
UAN-32 should be considered as a nitrogen source:
