Urea is a colorless, crystalline substance that is highly soluble in water. It is an organic compound made up of carbon, nitrogen, hydrogen, and oxygen, and is widely used in the agricultural and industrial sectors. Urea is the most widely used nitrogen fertilizer and is known for its high nitrogen content, making it a popular choice among farmers. Urea is synthesized from ammonia and carbon dioxide and is produced on an industrial scale through a process called the Haber-Bosch process. This process uses high pressure and temperature to convert ammonia and carbon dioxide into urea. The product is then cooled and dried to form solid urea crystals.
