Urea (carbamide) is a nitrogen fertilizer (contains 46,2% N in amide form).
Urea is produced using ammonia and carbon dioxide.
Unlike other nitrogen fertilizers nitrogen content in urea is the highest (46.2%) which accounts for its economical application to any soil for many agricultural crops as well as a fodder for the ruminants.
Urea can be used also for industrial purposes to produce melamine, cyanuric acid, urea- formaldehyde resins, pharmaceuticals and as an ingredient in cosmetics.
