Additional information

Urea is stable in aqueous solution. Hydrolysis is not seen and is not predicted based on a theoretical assessment of the structure of the molecule. Urea is considered to be readily biodegradable: the substance will be rapidly degraded by microorganisms present in the environment (as a nutrient and N-source) and subsequently incorporated into the nitrate cycle. Urea is additionally utilised as a N-source by terrestrial and aquatic plants.
