WASHINGTON, D.C. — Fertilizer prices are squeezing North American farmers, and they’re putting Canada’s role in the supply chain under fresh scrutiny. The investigation follows a tough year for fertilizer prices and farmers. Between January and June 2025, fertilizer prices in the U.S. rose as much as 39 per cent, and since it is a core agricultural input, American farmers have borne the brunt. In January, potash prices were up 11 per cent year over year, and UAN28, a liquid nitrogen fertilizer, was up more than 25 per cent. Agricultural trade access and supply-chain stability have long been part of CUSMA talks , so the questions hanging over fertilizer producers — particularly Nutrien — could surface in this summer’s talks.
