PHOSPHATE AND POTASH RECOGNIZED AS CRITICAL MINERALS: WHAT IT MEANS FOR WASHINGTON’S POTATO GROWERS

The U.S. Department of the Interior has officially added phosphate and potash to its final Critical Minerals List, a major win for American agriculture and fertilizer producers. The move, applauded by The Fertilizer Institute (TFI), underscores the strategic importance of these nutrients to U.S. food production and national security.

For Washington’s potato growers, this development is more than symbolic. It directly affects the cost and availability of two fertilizers essential for maintaining yield, quality, and soil health across the Columbia Basin and beyond.

A Strategic Shift for U.S. Agriculture

The Critical Minerals List, compiled by the U.S. Geological Survey, identifies materials essential to the nation’s economy and infrastructure resilience. Both phosphate and potash are cornerstones of modern fertilizer production, fundamental to nutrient management, tuber development, and sustainable agricultural growth.

While potash appeared on the 2018 list, both minerals were removed in 2022 before their reinstatement this month. The update reflects a federal shift toward strengthening domestic fertilizer supply chains at a time when global production remains highly concentrated abroad.

“Gaining this designation gives us a head start on trying to get some of those policies across the finish line,” said Ed Thomas, Vice President of Government Affairs for The Fertilizer Institute. “We can start rolling out some of these policies that will help increase domestic fertilizer supply and ease the burden of this tremendous investment.”

Thomas also noted that the supply chain shocks of recent years have laid bare how dependent U.S. farmers are on imports from just a few countries. “We’ve had supply chain shock after supply chain shock and demand keeps going up. We’ve got mines with existing reserves, but we can’t get to them. We want to be prepared for the future, and this is the next step for preparing for the long term, but it is going to take time.”

Why It Matters for Washington Potato Growers

Washington’s potato industry is uniquely sensitive to fertilizer access. Potatoes are among the most nutrient-intensive crops grown in the United States, and balanced inputs of phosphate and potash are critical for yield, quality, and storability. Any disruption in supply, whether through international conflict, trade restriction, or production bottlenecks, can ripple through the entire value chain, from field to processing plant.

By elevating phosphate and potash to “critical mineral” status, federal agencies can prioritize incentives for domestic production, infrastructure expansion, and research that strengthen the long-term fertilizer base. That recognition not only supports cost stability for growers, but also aligns with WSPC’s mission to promote efficient, sustainable production that feeds families worldwide.

Policy Outlook: Building Fertilizer Resilience Through Smart Policy

Recognizing phosphate and potash as critical minerals creates a policy foundation for federal and state action, and WSPC intends to ensure Washington’s potato growers have a seat at that table. The designation gives Congress and federal agencies new authority to prioritize fertilizer supply chain resilience within existing programs, including:

• Permitting and Production Incentives: The Department of the Interior and Department of Energy can now explore streamlined permitting for domestic mining, processing, and infrastructure projects tied to phosphate and potash production.
• Strategic Supply Chain Programs: The designation aligns with USDA’s Fertilizer Production Expansion Program and Rural Energy for America Program (REAP) funding, which can be leveraged to support domestic nutrient manufacturing and energy-efficiency improvements that lower production costs.
• Research and Innovation: The move opens the door for increased investment in applied agricultural research, including nutrient-use efficiency studies, recycling technologies, and soil-health innovations that reduce dependency on imports while improving sustainability outcomes.
• Trade and Geopolitical Resilience: By formally identifying phosphate and potash as critical minerals, the U.S. gains a stronger basis for trade policy interventions and diversification of supply partners. This directly supports WSPC’s long-standing advocacy for stable, fair, and predictable trade environments for all agricultural inputs and products.

For Washington’s potato sector, these federal and state initiatives represent both opportunity and responsibility. The Commission will advocate for policies that balance input affordability with environmental accountability, ensuring that efforts to “onshore” fertilizer supply chains reflect the realities of Western agriculture and the needs of irrigated specialty crop producers.

WSPC’s Role and Next Steps

The Washington State Potato Commission will continue to monitor how this designation translates into concrete policy, including potential funding, permitting reform, or R&D initiatives tied to nutrient security. WSPC will engage directly with both federal policymakers and state agencies such as the Washington State Department of Agriculture and Department of Ecology to ensure the state’s potato sector is represented in forthcoming discussions.

WSPC also plans to coordinate with national farm and fertilizer associations to ensure the unique needs of specialty-crop growers are recognized in future policy design. The Commission will advocate for solutions that maintain environmental stewardship while securing the reliable, affordable access growers need to remain competitive.

The Bottom Line

The addition of phosphate and potash to the U.S. Critical Minerals List is more than a regulatory update, it’s a recognition that food security and fertilizer access are intertwined. As policymakers move from designation to implementation, the Washington State Potato Commission will ensure Washington’s growers are part of shaping the path forward, promoting practical, balanced, and science-based policies that safeguard both our soils and our economy.
