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

One of the world's largest ammonia producers; Donaldsonville Complex (Louisiana) is the world's largest single ammonia production complex — 4.335M MT/year capacity, 6 plants on 1,400 acres along the Mississippi River. Produced 9.8M MT gross ammonia in 2024 across all facilities. Also operates plants in Iowa, Louisiana, Courtright (Ontario Canada), Ince (UK), Billingham (UK). Added CO2 capture at Donaldsonville (2025) enabling ~1.9M MT/year 'low-carbon ammonia' for export to Japan/Korea. Joint venture with JERA + Mitsui for $4B 'blue ammonia' plant in Louisiana.

World's largest potash producer with 6 Saskatchewan mines. Vanscoy mine (west of Saskatoon) uses solution mining technology — fresh water drawn from the Saskatchewan River (~20km pipeline) is used in brine management. Deep subsurface saline aquifer brine injection used for waste disposal at Vanscoy (injected into Winnipeg/Deadwood Formations at 1,500-1,700m depth). Conventional underground mines at Rocanville, Allan, Lanigan, Cory, Belle Plaine also produce waste brine requiring aquifer disposal. Nutrien operates Canada's only solution potash mine at Vanscoy. Plans to reach 18M MT/year Saskatchewan capacity.

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.

World's largest nitrogen fertilizer company; Norwegian state partial ownership; produces urea, nitrate, and NPK fertilizers critical for rice production globally
