Urea, or carbamide, is an organic compound with the chemical formula (NH 2) 2 CO that is synthesized from natural gas, not urine as frequently misstated. Management of urea fertilizer to minimize volatilization. . The prills used to be the primary form of urea, but they have been surpassed by granules which are larger, harder, and more stable under high humidity. Therefore, in addition to soil applications, urea fertilizers can be also used in fertigation or as a foliar application. Although this urea is artificially produced, its composition is the same as that produced by the body. As a general rule, urea should not be applied on the soil surface  or top dressed on sods or crop residues without immediate incorporation. Urea can also be dissolved in water and used as a soil drench or otherwise distributed with irrigation water or applied as foliar spray.
