Fertilizers
Urea, a white crystalline solid containing 46% nitrogen, is widely used in the agricultural industry as an animal feed additive and fertilizer.
Urea is used as a nitrogen release fertilizer as it hydrolyses back to 2NH2 and CO2 but its most common impurity (biuret, NH2-CO-NH-CO-NH2) must be present at less than 2% as it impairs plant growth.
It is also used in many multi-component solid fertilizer formulations. Its action of nitrogen release is due to the conditions favoring the reagent side of the equilibriums which produce urea.
