Overview
Urea (CO(NH₂)₂) is a synthetic organic compound widely used as a nitrogen fertilizer in agriculture and as a feedstock in chemical industries. With a nitrogen content of 46% by weight, it is the most concentrated solid nitrogen fertilizer available on the market, offering cost-effective nutrient delivery for crops. Urea is also used in the production of resins, plastics, adhesives, and as a key input in diesel exhaust fluid (DEF/AdBlue®) for emissions control.
