UAN Solution (Urea Ammonium Nitrate, 28-32% N)

Urea ammonium nitrate (UAN) solution, typically 28-32% nitrogen by weight, is a non-pressurized liquid nitrogen fertilizer applied by sprayer or injected into irrigation systems. Preferred over solid fertilizers for precision agriculture due to variable-rate application ease. US corn belt is the largest UAN market. Key producers: CF Industries, Koch Fertilizer, Yara, Nutrien. UAN is also used as a diesel exhaust fluid (DEF/AdBlue) precursor via urea separation.

Uralchem / TogliattiAzot (ToAz)

HQ RU

Russian nitrogen/ammonia holding company controlling TogliattiAzot (ToAz) — formerly the world's largest single ammonia plant (2M+ MT/year capacity). ToAz exported 2M MT/year via the 2,471km Togliatti-Odessa pipeline to the Black Sea port of Odessa (Pivdenny). Pipeline shut since Russia invaded Ukraine (February 2022). Uralchem reported 'colossal losses' from the shutdown. Before the war, ToAz ammonia represented ~1.3% of global supply from a single facility. Controlled by Dmitry Mazepin (personal EU sanctions). Russia demands pipeline reopening as condition for grain corridor deals.
