Description

Urea (CO(NH₂)₂) is the world's most widely used nitrogenous fertilizer, containing approximately 46% nitrogen by weight — the highest nitrogen content of any solid fertilizer. It is produced synthetically from ammonia and carbon dioxide through the Haber-Bosch process. Beyond agriculture, urea is also an important industrial chemical used in plastics manufacturing, resins, and as a diesel exhaust fluid (DEF/AdBlue).
