Urea is an organic compound with chemical formula CO(NH2)2.It is a colorless, odorless solid, highly soluble in water, and practically non-toxic. More than 90% of world industrial production of urea is destined for use as a nitrogen-release fertilizer . Urea has the highest nitrogen content of all solid nitrogenous fertilizers in common use. Therefore, it has the lowest transportation costs per unit of nitrogen nutrient. Urea is used in many multi-component solid fertilizer formulations. It is highly soluble in water and is therefore also very suitable for use in fertilizer solutions (in combination with ammonium nitrate). Urea absorbs moisture from the atmosphere and therefore is typically stored either in closed or sealed bags on pallets or, if stored in bulk, under cover with a tarpaulin. As with most solid fertilizers, storage in a cool, dry, well-ventilated area is recommended. Urea is on of the important material used to make urea-formaldehyde resins , ureamelamine-formaldehyde ,urea nitrate and other vital adhesives.
