Urea, also known as carbamide, is an organic compound with chemical formula CO(NH 2) 2.This amide has two –NH 2 groups joined by a carbonyl (C=O) functional group.. 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.
Solid urea is the largest nitrogen fertilizer product which is produced in two forms of granules and prills.
