Fertilizer Crisis Pushes Farmers Away from Wheat, Corn and Canola Worldwide

The global fertilizer crisis of 2026 is fundamentally altering crop planting decisions across every major agricultural region. Triggered by the near-total closure of the Strait of Hormuz following the escalation of the U.S.-Israel-Iran conflict on February 28, 2026, this disruption has removed approximately 35% of the world's seaborne urea and phosphate supply from the market. Farmers from the American Midwest to the Australian wheat belt are now abandoning nitrogen-intensive crops in favor of lower-input alternatives, reshaping global food production in ways that could reverberate for years.

The Strait of Hormuz normally carries around 30% of all globally traded fertilizers. Three of the world's top ten urea exporters ship their products through this narrow waterway. When maritime traffic through the Persian Gulf dropped by over 95% in early March 2026, the consequences for fertilizer availability were immediate. Urea prices in the United States surged from roughly $450 per ton in late February to over $700 per ton by mid-March, an increase of approximately 50% in under three weeks. At Australian ports, urea was quoted at around A$1,350 per ton, up 60% since the beginning of the conflict. In the U.S. Gulf, prices continued climbing past $800 per ton by late March.

The timing of this supply shock could not have been worse. Northern Hemisphere farmers were entering the critical spring planting window, the period when fertilizer purchasing decisions are finalized and applications begin. Unlike oil, there are no strategic reserves for fertilizer. Once the planting window closes, missed applications cannot be made up later.

In the United States, the impact is already visible in planting intentions. The USDA projects corn acreage for 2026 at approximately 93 million acres, a sharp decline from nearly 99 million acres planted in 2025. Corn is the most nitrogen-intensive major crop, and with urea-to-corn price ratios reaching record highs, many farmers are pivoting to soybeans, which require significantly less fertilizer input. Illinois corn producers are projected to spend around $229 per acre on fertilizer alone in 2026. The estimated loss per acre for corn now exceeds $200, while soybean losses are roughly $75 per acre less, making the switch an economic survival strategy rather than a preference.

Australia presents a similar pattern with different crops. As the world's fourth-largest wheat exporter and second-largest canola supplier, Australia's planting decisions carry global weight. Farmers there are expected to favor less nitrogen-intensive crops such as barley over wheat and canola during the upcoming season. Australian diesel prices have risen 88% since the start of the conflict, compounding the fertilizer cost burden. Analysts at Commonwealth Bank of Australia report that growers are actively reducing fertilizer application rates and switching from nitrogen-hungry crops into feed barley. Wheat acreage could decline by as much as 15% this season.

Australia is almost entirely reliant on imported urea, having brought in 3.85 million tonnes in 2024, most of it from the Middle East. When Chinese export restrictions limited that supply route, buyers turned to Indonesia and then the Middle East, only to find the Strait of Hormuz already closed. Fertilizer and fuel costs together represent 25 to 30% of a typical Australian cropping operation's total expenses, and a sharp increase in both is severely eroding farm profitability.

The crisis extends well beyond the U.S. and Australia. Brazil, the world's largest exporter of soybeans and corn, imports approximately 85% of its fertilizer needs. The lack of available potash and phosphates from Gulf producers threatens to reduce planted acreage for upcoming seasons. India, where agriculture supports over 100 million farming families, depends on imported fertilizer inputs and natural gas from routes passing through the Strait of Hormuz for 30 to 35% of its supply. Some domestic fertilizer plants are running below capacity due to natural gas shortages, and farmers in states like Punjab report growing uncertainty about input availability ahead of the monsoon planting season.

In South and Southeast Asia, the exposure is particularly acute. Fertilizer producers in India, Bangladesh, and Pakistan have been forced to reduce or halt production after losing natural gas supplies from Qatar. Egypt, which accounts for roughly 8% of global urea trade, has seen its production capacity cut in half after losing Israeli gas imports, forcing plants into emergency maintenance.

Across sub-Saharan Africa, the situation is especially concerning. The continent imports approximately 90% of the fertilizer it consumes, and many farmers operate with extremely narrow margins. West Africa is entering its primary rainy season and requires fertilizers to already be in-country or moving through supply chains. The International Fertilizer Development Center (IFDC) has warned that the crisis is evolving from a supply chain disruption into a food security emergency for the continent.

European farmers face a compounding problem. Natural gas prices on the continent have spiked above 60 euros per megawatt-hour, keeping nitrogen production at roughly 75% of normal capacity, a level that has persisted since the Russia-Ukraine war disrupted energy markets in 2022. Germany's fertilizer plants are being shut down because they can no longer operate economically without access to affordable gas. In February 2026, the EU Commission proposed temporarily suspending tariffs to facilitate alternative imports from North Africa and the United States.

China, the world's largest producer of nitrogen and phosphate fertilizers, has responded to the crisis by restricting exports to protect domestic supply. Urea shipments have been curtailed, and exports are not expected to resume until at least August 2026. This move removes millions of tonnes from the global market during the most critical months of the planting calendar. Russia has also suspended ammonium nitrate exports for at least one month, citing the need to prioritize domestic spring planting.

The financial toll is substantial and growing. Bank of America has warned that the conflict threatens 65 to 70% of global urea supplies. Fertilizer accounts for 33 to 44% of corn operating costs and 34 to 45% of wheat operating costs in the United States alone. Globally, the additional cost burden from the price surge is estimated in the tens of billions of dollars per month across all affected agricultural markets. Food prices could rise 12 to 18% above pre-crisis levels by the end of 2026, according to analysis from Helios AI.

The crop rotation shift underway is not just an economic adjustment. It carries long-term consequences for global food supply. Reduced wheat and corn production could lead to tighter grain supplies and higher consumer food prices by late 2026 and into 2027. The shift toward lower-input crops like soybeans, barley, and pulses may create temporary surpluses in those markets while creating deficits in staple grains. Livestock feed availability could also be affected, potentially driving up meat and dairy prices.

For now, the global agricultural sector is operating in a state of heightened uncertainty. The duration of the Strait of Hormuz disruption, the status of Chinese export restrictions, and the trajectory of energy prices will determine how severe the downstream impacts become. What is already clear is that the fertilizer crisis of 2026 has exposed the extreme fragility of the global food production system and its dependence on a handful of critical supply chain chokepoints.
