If Trump tariffs fertilizer, U.S. lacks reserves ‘to meet domestic demand’
Global News
In a statement, Fertilizer Canada said increasing fertilizer production 'cannot happen overnight and can take 10 to 15 years to increase.'
Canada’s fertilizer industry says U.S. President Donald Trump’s threat of “very severe” tariffs will “jeopardize” North American agricultural supply chains if they’re imposed, warning the U.S. doesn’t have enough potash reserves to replace Canadian imports.
Trump said Monday while announcing billions in government aid for American farmers hurting from higher prices — including on fertilizer — that he may tariff Canadian fertilizer “if we have to” in order to bolster domestic production.
In a statement, Fertilizer Canada said increasing fertilizer production “cannot happen overnight and can take 10 to 15 years to increase.”
“Imposing tariffs jeopardizes the deeply integrated, open trading relationship that is vital to North American agricultural producers,” the statement said.
“To protect the competitiveness of North American farmers, access to a reliable supply of tariff-free fertilizer is essential.”
U.S. farmers rely on Canadian potash fertilizer from Saskatchewan in order to add potassium to their soils. Canada has the largest potash reserves in the world, with more than 1.1 billion tons — accounting for over one-third of the world’s reserves — compared to 220 million tons in the U.S., according to the U.S. Geological Survey.
The U.S. “does not have sufficient reserves to meet domestic demand,” Fertilizer Canada said, noting American farmers used 5.3 million tons of potash in 2023 while the country produced about 400,000 tons. Canada produced an estimated 21.9 million tons of potash in 2023.
The U.S. Geological Survey said 79 per cent of potash imports came from Canada between 2020 and 2023.
