Fertilizer prices have surged 40% over the past three months following the outbreak of the Iran War, which has effectively cut off access to the Strait of Hormuz through which roughly 30% of the world's fertilizers previously passed, according to reporting by the Associated Press. The price spike is raising concerns among agricultural economists and policymakers about potential ripple effects on grocery prices for American consumers.
The commodity is essential to growing or producing virtually every item in a grocery store, from vegetables to grains to feed for livestock. Dan Scheitrum, who teaches agribusiness at Cal Poly's College of Agriculture, said the price increases will affect nearly all agricultural sectors. "Everything else equal, we expect to see higher prices for corn, soybeans, wheat, potatoes, strawberries – everything that uses fertilizer," Scheitrum said in comments provided to Nexstar.
The United Nations World Food Program has warned that the disruption will have a "devastating impact" on crop yields and food availability for months to come. The timing is particularly acute because many farmers have already completed their spring planting season, meaning they either lacked sufficient fertilizer or paid premium prices to secure supplies. A rice farmer in Arkansas told The Economist that his fertilizer costs jumped by $50 per acre, increasing his total production expenses by $200,000 for the growing season.
What the Left Is Saying
Progressive Democrats and food security advocates are using the fertilizer crisis to renew calls for domestic agricultural resilience and reduced dependence on global supply chains vulnerable to geopolitical disruption. Senator Amy Klobuchar of Minnesota said in a statement that the situation "underscores why we must invest in American agricultural infrastructure and reduce our vulnerability to conflicts halfway around the world."
The Progressive Caucus has long advocated for measures including strategic grain reserves and federal support for domestic fertilizer production facilities. Representative Chellie Pingree of Maine, who sits on the House Agriculture Committee, argued that the current crisis demonstrates the need for the government to play a larger role in stabilizing agricultural inputs. "When global instability can so quickly translate into empty plates at American dinner tables, we cannot rely on the market alone to protect families," Pingree said.
Environmental groups have also weighed in, with some arguing the episode highlights the importance of reducing reliance on synthetic fertilizers through regenerative farming practices. The Organic Center has pointed to organic agriculture methods as a potential buffer against volatile input markets, though acknowledged that such transitions take years to implement at scale.
What the Right Is Saying
Conservative Republicans and free-market advocates argue the episode illustrates the dangers of policy decisions that have made America dependent on foreign energy and agricultural inputs. Senator Tom Cotton of Arkansas said the crisis "is a direct consequence of our failure to achieve energy independence and develop domestic fertilizer production capacity."
The Heritage Foundation has published analysis arguing that regulatory barriers have prevented American companies from building new fertilizer manufacturing facilities, leaving supply vulnerable to international disruptions. The organization called for streamlining permitting processes and reducing environmental regulations that increase production costs.
Other conservative voices have focused on the broader foreign policy implications. Senator Marco Rubio of Florida wrote in an op-ed that "the Strait of Hormuz closure proves we must reorient our Middle East strategy toward ensuring free passage of critical commercial goods." Some Republican lawmakers have called for increased naval presence in the region to protect shipping lanes, while others have advocated for diplomatic efforts to de-escalate the Iran conflict.
What the Numbers Show
The fertilizer price increase follows a 40% spike over three months reported by the Associated Press at the end of May. According to the United States Department of Agriculture, fertilizer comprises between 33% and 44% of operating costs for corn production, and between 43% and 45% of operating costs for wheat—making these crops among the most vulnerable to price swings.
The impacts extend beyond plant agriculture. The majority of U.S. corn production goes toward animal feed for cattle, hogs, and poultry, meaning higher fertilizer prices indirectly affect meat prices as well. Scheitrum noted that "the corn that we grow, most of it is for animal feed. This goes to cows, hogs, poultry, and it's a main component of the cost of producing beef, chicken."
Overall food inflation reached its highest level in three years last month, with food prices rising approximately 3% year-over-year. Fruits and vegetables saw price increases of around 6%, while tomato prices alone jumped by 32%. The fertilizer disruption joins other pressures including elevated gas prices affecting transportation costs, the worst wheat crop in decades, drought conditions impacting cattle ranching, concerns about the New World screwworm, and ongoing tariff volatility—all contributing to consumer price pressures.
The Bottom Line
The surge in fertilizer prices represents a significant test of both agricultural policy and geopolitical strategy. While some relief may come if the Iran conflict de-escalates and the Strait of Hormuz reopens, economists warn that much of the damage to this year's growing season has already been done.
Farmers face difficult choices: reducing planted acreage is not an option for those with orchards or perennial crops like vineyards and fruit trees that cannot be easily scaled back. Using less fertilizer risks smaller yields, which paradoxically can lead to higher consumer prices despite lower production volumes. The World Food Program's warning of months-long impacts suggests the price pressure will persist well beyond any near-term resolution of the underlying conflict.
For policymakers, the crisis has revived debates about strategic reserves, domestic manufacturing capacity, and agricultural supply chain resilience. For consumers, the outlook includes continued upward pressure on grocery prices across a wide range of food categories—from bread and cereals to vegetables to meat products—barring significant improvement in either geopolitical conditions or agricultural input availability.
