Urea 46%, also known as carbamide, is an organic compound with the chemical formula CO(NH2)2. It is a colorless, odorless solid, highly soluble in water, and practically non-toxic. Dissolved in water, it is neither acidic nor alkaline. The introduction and the scientific invention of Urea are identified as life-changing events in the history of agriculture. Urea N46% is the world's most common nitrogen fertilizer and has been used uniformly in all the agricultural lands of the world. Never before this, agriculture had seen such booming heights in production as well as prosperity. Urea is neutral in pH and can adapt to almost all kinds of soils. It is a waste product formed naturally by metabolizing protein in humans as well as other mammals, amphibians, and some fish. Urea is widely used in the agricultural sector both as a fertilizer and animal feed additive.

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 rats). Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, most notably nitrogen excretion. The liver forms it by combining two ammonia molecules (NH3) with a carbon dioxide (CO2) molecule in the urea cycle. Urea is widely used in fertilizers as a source of nitrogen (N) and is an important raw material for the chemical industry.
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 low transportation costs per unit of nitrogen nutrient. The most common impurity of synthetic urea is biuret, which impairs plant growth. Urea breaks down in the soil to give ammonium. The ammonium is taken up by the plant. In some soils, the ammonium is oxidized by bacteria to give nitrate, which is also a plant nutrient.
The loss of nitrogenous compounds to the atmosphere and runoff is both wasteful and environmentally damaging. For this reason, urea is sometimes pretreated or modified to enhance the efficiency of its agricultural use. One such technology is controlled-release fertilizers, which contain urea encapsulated in an inert sealant. Another technology is the conversion of urea into derivatives, such as formaldehyde, which degrades into ammonia at a pace matching plants' nutritional requirements.
Resins
Urea is a raw material for the manufacture of two main classes of materials: urea-formaldehyde resins and urea-melamine-formaldehyde used in marine plywood.
Miscellaneous uses
An ingredient in diesel exhaust fluid (DEF), is 32.5% urea and 67.5% de-ionized water. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water.
A component of animal feed provides a relatively cheap source of nitrogen to promote growth.
A non-corroding alternative to rock salt for road de-icing. It is often the main ingredient of pet-friendly salt substitutes although it is less effective than traditional rock salt or calcium chloride.
The main ingredient in hair removers such as Nair and Veet.
A browning agent in factory-produced pretzels.
An ingredient in some skin creams, moisturizers, hair conditioners, and shampoos.
A cloud seeding agent, along with other salts.
A flame-proofing agent is commonly used in dry chemical fire extinguisher charges such as the urea-potassium bicarbonate mixture.
An ingredient in many tooth whitening products.
An ingredient in dish soap.
Along with diammonium phosphate, as a yeast nutrient, for fermentation of sugars into ethanol.
A nutrient used by plankton in ocean nourishment experiments for geoengineering purposes.
As an additive to extend the working temperature and open time of hiding glue.
As a solubility-enhancing and moisture-retaining additive to dye baths for textile dyeing or printing.
As an optical parametric oscillator in nonlinear optics.
