Urea, also known as carbon amide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. One of the simpler organic compounds is the main nitrogen-containing end product of protein metabolism in mammals and certain fish species. It is also a nitrogen fertilizer with a high nitrogen content.
As a neutral fertilizer, urea is suitable for a variety of soils and plants. It is easy to store, easy to use, and has little effect on soil destruction. It is a chemical nitrogen fertilizer that is currently used in large quantities. Industrially, ammonia and carbon dioxide are used to synthesize urea under certain conditions.
