Urea is the most popular and economical of all nitrogen-based fertilisers used worldwide. It is exceptionally versatile and can be used in a range of environmental conditions on a wide variety of crops. Urea is also a major raw material for industrial products, including melamine.
Urea or carbamide is an organic compound with the chemical formula CO(NH2)2. Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is a colorless, odorless solid, highly soluble in water and practically non-toxic (LD50 is 15 g/kg for rat). Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, the most notable one being nitrogen excretion. Urea is widely used in fertilizers as a convenient source of nitrogen. Urea is also an important raw material for the chemical industry.
