Urea
Urea is an organic compound that occurs naturally as a product of excretion in living organisms, and is produced industrially by reacting ammonia with carbon dioxide. Urea's main use is as a fertilizer in the form of granules, prills or in aqueous solution. Urea is also an important ingredient for the manufacture of melamine, and for urea-formaldehyde resins, which are used as adhesives for wood products, paper and textiles.
