GENERAL

The Claim

Urea ammonium nitrate solution (UAN) is a liquid nitrogen fertilizer made primarily from urea, ammonium nitrate, and water.

Verified by Lenz ·

The Short Version

The evidence strongly supports this description of UAN. Authoritative chemical, academic, and agricultural sources consistently identify it as a liquid nitrogen fertilizer whose main components are urea, ammonium nitrate, and water. Minor additives may appear in some commercial formulations, but they do not change the product’s primary composition.

Caveats

  • Some commercial UAN formulations may contain minor additives such as corrosion inhibitors or dyes.
  • A production process may generate ammonium nitrate in situ from nitric acid and ammonia, but that does not change the final composition described in the claim.
  • The claim concerns primary composition, not an exhaustive ingredient list or a specific manufacturing route.
