China Comes for Canadian POTASH — Trump’s Farm Belt Loses Its Fertilizer Lifeline Did you know that the United States depends on Canada for most of its potash fertilizer? Nearly 90% of the potash used by American farmers is imported, and more than 80% of that comes from Saskatchewan, Canada.

Potash is essential for growing corn, wheat, and soybeans. Without it, crop yields fall and food prices rise. Yet despite this dependence, the Trump administration repeatedly threatened tariffs on Canadian potash, risking higher costs for American farmers already struggling with tight profit margins.
At the same time, Canada has been expanding its export capacity toward Asia. Major producers like Nutrien are investing in new terminals designed to serve growing markets in China and India. As global fertilizer demand rises, Canada is gradually reducing its reliance on the U.S. market.
The reality is simple: America has no quick alternative source of potash. Building new mines would take years, even decades. That means any disruption in Canadian supply could directly affect farm costs, food prices, and ultimately consumers across the United States.
This isn’t just a trade story. It’s a food security story, and one that could shape North American relations for years to come.
