Should the U.S. prioritize domestic fertilizer production to strengthen national food security?
American Fertilizer has proposed a $4.7 billion nitrogen fertilizer plant at the Swan Ranch Industrial Park in Cheyenne, Wyoming. The facility aims to serve Western U.S. agricultural markets and expects to reach full production by 2031.
Why it matters
Currently, 92% of U.S. fertilizer production sits east of the Rockies, leaving Western operations heavily dependent on expensive imports. Localizing production could significantly lower supply chain risks and transportation costs for regional agribusinesses.
The proposed $4.7 billion facility aims to serve a market with 5 million tons of annual nitrogen demand, with 66% of U.S. urea imports currently sourced from five foreign nations. The project anticipates creating 1,600 construction jobs and 300 permanent full-time roles.
The players
American Fertilizer
A developer headquartered in Windsor, Colorado, focused on large-scale industrial fertilizer production facilities.
Union Pacific
A major North American railroad company providing freight transport infrastructure for industrial products.
Burlington Northern
A Class I railroad network integral to moving agricultural and industrial commodities across the Western United States.
The details
The facility will process Wyoming-sourced natural gas into ammonia, urea, UAN32, and diesel exhaust fluid. Once operational, the plant will utilize Union Pacific and Burlington Northern rail lines to distribute products across the 12 most-western states. The 600-acre site at Swan Ranch is positioned to capture regional logistics advantages by shortening the distribution chain for Western farmers.
Timeline
2025: Five nations supplied 66% of U.S. urea imports.
2031: The target year for the facility to reach full production.
Market Landscape
The project marks a strategic attempt to invert the industry trend where 92% of production capacity is located east of the Rocky Mountains. It aims to reduce reliance on the 36% of U.S. urea supply currently sourced from international imports.
Operators in the Western U.S. agricultural sector should monitor the project's permitting progress, as it could provide a domestic alternative to international urea sources by 2031. Assessing long-term contract pricing against current import-heavy supply chains is advisable for procurement teams.
The takeaway
The proposed facility signals a potential shift toward localized fertilizer production for the Western U.S. agricultural market. Business owners should track the 2031 production timeline and evaluate how a reliable domestic supply of ammonia and urea might hedge against future import price volatility.
