# Reliance on potash imports remains a challenge for the U.S. agriculture sector

Publication Date: 02.04.2025, 12:00

Trump push for US fertilizer won’t be enough to replace imports.

In a recent initiative, President Donald Trump has targeted potash as a critical mineral needing significant enhancement in U.S. production levels. Despite this effort, it appears unlikely to substantially diminish the United States’ dependence on imported fertilizers.

Currently, the U.S. imports about 90% of its potash, predominantly from Canada, the leading global producer. This mineral is essential for the cultivation of corn and soybeans—America’s largest agricultural output. Domestic potash production constitutes less than 1% of the national demand, a statistic highlighted by Corey Rosenbusch, Chief Executive Officer of the Fertilizer Institute.

“Even with increased production, our dependency on Canadian potash will persist,” Rosenbusch commented in a recent interview. The looming prospect of new U.S. tariffs on Canadian fertilizers, potentially ranging from 10% to 25%, compounds the issue. Such tariffs could elevate operational costs for farmers, potentially trickling down to increased consumer prices.

Amidst these developments, the Fertilizer Institute has been lobbying for potash to be recognized on the federal government’s permanent list of critical minerals vital for national security and economic stability. “Securing a spot on this list would strengthen our position when advocating for specific exemptions,” Rosenbusch noted, although he acknowledged that no outcomes are guaranteed.

On the domestic front, Michigan Potash & Salt Co. actively seeks to expand U.S. potash production. The company has discovered a significant deposit in Michigan, estimated to be worth as much as $65 billion. “By 2028, we aim to meet about 10% of the U.S. potash requirement, potentially expanding up to 40% with this single reserve,” said Aric Glasser, Chief Operating Officer of the company.

This push for increased domestic production comes at a critical juncture as the U.S. agriculture sector prepares for the planting season, highlighting the ongoing challenges of reducing reliance on foreign resources.
