Urea, chemically known as CO(NH₂)₂, is one of the most widely produced organic compounds in the world, primarily used as a nitrogen-rich fertilizer. Appearing as a white crystalline solid, urea is highly soluble in water and provides an essential source of nitrogen for crops, boosting agricultural productivity. It is easy to store, transport, and apply, making it the most popular fertilizer globally. Beyond agriculture, urea is used in industry as a raw material for manufacturing plastics, adhesives, and resins, especially urea-formaldehyde resins. In medicine, it is employed in skin creams as a moisturizing agent and in certain diuretic drugs. It also serves as a feed supplement for livestock, supplying non-protein nitrogen that ruminants can convert into protein. Biologically, urea is naturally produced in the liver as part of the body’s nitrogen excretion process and is present in urine. While safe and stable under proper storage, excessive agricultural use can lead to soil degradation and water pollution due to nitrogen leaching. Nonetheless, its affordability, effectiveness, and versatility make urea indispensable in agriculture, industry, and healthcare.
