Audited Supplier Urea, also known as carbamide, is an organic compound with 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. introduction and scientific invention of Urea is identified as a life changing event 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.
