CAS 57-13-6
Urea
Urea (46% N) is the most concentrated solid nitrogen fertiliser, supplied prilled and granular for direct application and blending.
Urea is made by reacting ammonia with carbon dioxide and contains 46% nitrogen — more than any other solid fertiliser — which keeps freight and application costs per unit of nitrogen low. In soil it is converted to ammonium and then nitrate, feeding crop growth.
Prilled urea has small, round particles and dissolves quickly, suiting top-dressing and solution fertilisers. Granular urea has larger, harder particles that blend evenly with other granular fertilisers in NPK blends and spread further. Technical grades are used to make urea-formaldehyde resins; specialised high-purity grades are used for diesel exhaust fluid.

Urea — frequently asked
Prilled urea has smaller, softer particles that dissolve quickly and suit top-dressing and solutions. Granular urea has larger, harder particles that resist breakage, spread further and blend evenly in NPK bulk blends.
Biuret forms during urea manufacture and can damage sensitive crops, especially in foliar sprays. Fertiliser-grade urea is typically limited to 1.0% biuret or less, with low-biuret grades for foliar use.
