Urea Granular

Urea is the world’s most commonly used nitrogen fertilizer and indeed more urea is manufactured by mass than any other organic chemical.  Containing 46% N, it is the most concentrated nitrogen fertilizer, and is readily available as free-flowing prills (granules). While over 90% of urea produced is used as a fertilizer, it has other uses, which include the manufacture of the melamine, used in melamine-methanal resins. Urea itself also forms important resins. An increasingly important use of urea is in reducing air pollution from diesel engines in cars, buses and lorries.
