WINNIPEG - March 16, 2026. U.S. farmers are facing tightening fertilizer supplies and rapidly rising prices just weeks before spring planting after the war involving Iran disrupted global trade routes through the Strait of Hormuz. The conflict has already pushed fertilizer prices up more than 30% worldwide, threatening crop production and farm profitability at a time when many producers are already dealing with weak commodity prices and high input costs.

The disruption is particularly concerning for the United States because the country imports significant volumes of nitrogen fertilizers, including urea, which is widely used for corn and wheat production. According to industry data, the U.S. market is currently about 25% short of its normal fertilizer supplies for spring application, creating a serious challenge for farmers preparing fields for the 2026 growing season.

The shortage stems largely from disruptions to shipments moving through the Strait of Hormuz, a vital global shipping corridor that links fertilizer exporters in the Persian Gulf with major agricultural markets around the world.

More than 30% of global nitrogen fertilizer exports, along with key fertilizer components such as sulphur, typically pass through the strait. With the waterway effectively closed due to military tensions, shipments have stalled and global supply chains have tightened rapidly. Industry analysts warn that the situation could worsen if fertilizer cargoes originally destined for the United States are redirected to other regions offering higher prices.

In the key U.S. fertilizer import hub of New Orleans, domestic prices are currently as much as $119 per metric ton lower than global market prices, according to fertilizer market analyst Josh Linville of StoneX. That price gap could encourage suppliers to reroute shipments away from the U.S. market. Linville said the risk is not only that incoming vessels could be diverted, but that existing fertilizer supplies already in the U.S. could potentially be exported if overseas buyers are willing to pay significantly more.

Across North America, many farmers are already feeling the impact of the shortage.

Producers who did not secure fertilizer earlier in the season are now encountering empty retail supply centers or sharply higher prices. Some dealers have even stopped offering quotes due to the volatility and uncertainty surrounding available supplies. For example, Canadian farmer David Altrogge said he purchased his fertilizer in December, but buying the same amount today would cost an additional C$44,000 (about $32,000). Other farmers in his region may face those price increases-or may not be able to secure fertilizer at all.

The situation is especially alarming because fertilizer distribution typically operates on a "just-in-time" supply chain model, meaning inventories at retail locations are limited. "It's not like there's a lot of fertilizer sitting on the shelf," said Veronica Nigh, an economist at The Fertilizer Institute. "The system is designed to move product quickly rather than store large volumes."

The timing of the disruption is particularly problematic because fertilizer must be applied before crops begin their growth cycle. Shipments leaving the Middle East normally take weeks to reach North American ports. Once unloaded, fertilizer must still move through a complex network of barges, rail, and truck transportation before reaching farms across the Midwest and Plains.

If supplies arrive too late, they may not be usable for the 2026 planting season, potentially reducing crop yields and tightening grain supplies later in the year. Agricultural groups warn that fertilizer shortages could ultimately ripple across the entire food system, affecting crop production, livestock feed supplies, and consumer food prices.

The U.S. government is now exploring emergency measures to stabilize fertilizer supplies. The Treasury Department announced steps to allow increased fertilizer imports from Venezuela, part of a broader strategy to support agricultural production and offset supply disruptions linked to the war.

However, analysts caution that Venezuela's fertilizer industry has declined significantly in recent years and cannot quickly scale up production without major investment. Meanwhile, policymakers in Washington are raising concerns about the rapid rise in fertilizer prices. Senator Josh Hawley has called for a federal investigation into possible price gouging by fertilizer companies, noting that prices have surged more than 30% since the conflict began.

Agriculture Secretary Brooke Rollins said the administration is examining multiple options to help farmers manage rising input costs, including potential financial assistance programs. The federal government is already distributing $12 billion in aid to farmers, but farm groups are urging Congress to approve additional support if the fertilizer crisis continues into the planting season.
