Due to it's high nitrogen content, the majority of urea is used to make fertiliser. Nitrogen helps plants grow quickly and aids in the production of a healthy and abundant crop. In addition to providing ample nitrogen, urea is also useful because it can be used as either a solid or a solution. In addition, there are very few hazards associated with the use of urea, and it does not release as many pollutants into the air as other nitrogen sources.
Urea is also found in cattle feed, because it provides the animals with a good source of nitrogen.
The high nitrogen content found in urea is useful to the cosmetic industry as well. A number of skin creams contain urea because it helps to moisturise and nourish skin.

Another advantage of using urea in skin creams is that it requires fewer preservatives to maintain product freshness.
Urea is also used to help improve the environment. In addition to its use as a fertiliser, which does not pollute the air, urea also lowers NOx emissions in vehicles.
