A bag of urea fertilizer has no brand loyalty and no headline appeal. Yet trace its journey backward from an American dinner table and you arrive, in eleven quiet steps, at a gas field beneath the Qatari desert. That journey is the actual supply chain feeding the world's most productive farmland, and it is now under direct threat.
It begins with cheap, abundant natural gas from Qatar's North Field, converted through the century-old Haber-Bosch process into ammonia, then granulated into urea at complexes like QAFCO. From there it is bulk-loaded at Ras Laffan or Mesaieed, and sails through the 33-kilometre Strait of Hormuz before crossing the Indian Ocean and Atlantic to US Gulf ports such as New Orleans. Barges move it up the Mississippi; rail and truck carry it to regional co-ops; and in a narrow spring planting window, American farmers apply it to Corn Belt soil. Corn and soybeans absorb that nitrogen, are harvested, crushed, milled and fed — and resurface months later as meat, dairy, eggs, cooking oil and processed food on a consumer's plate.
Step five in that chain — the Hormuz transit — is the single point of failure for a supply chain that otherwise looks robust. It is also, right now, a war zone.
The Gulf Feeds the World's Soil Before It Feeds Its Engines
Few outside the fertilizer trade appreciate how concentrated global nitrogen supply has become. Gulf countries accounted for 36% of global urea exports between 2023 and 2025, with Iran and Qatar the largest exporters, followed by Saudi Arabia. Widen the lens to the full at-risk region and nearly 49% of global urea exports and about 30% of global ammonia exports originate from countries exposed to Middle East disruption. Qatar alone is disproportionate to its size: its QAFCO complex accounts for 14% of global urea trade, built on the same cheap natural gas that makes ammonia synthesis economic nowhere else at this scale.
One Qatari complex's exports were, as of 2022, keeping nearly 43 million people fed across the US, Brazil, and India — before this year's disruptions even began.
Who Gets Hit, and How Hard
The trade flows most exposed are not evenly distributed, and that unevenness is the story:
• India — buys more than 40% of its urea from the region, and has already seen fertilizer protests erupt on false rumours of stalled shipments.
• Australia — depends on the UAE, Qatar, and Saudi Arabia for more than half of its urea.
• The United States — sources 35% of its imported urea supply, 40% of processed phosphates, and 10–20% of sulphur from countries exposed to this conflict; and even where cargo isn't Gulf-sourced, American farmers feel the disruption because urea is a globally priced commodity.
• Europe — less exposed on urea directly, but vulnerable on gas: when Qatari LNG output was hit, Dutch TTF gas prices jumped as much as 51% in a single week, squeezing European ammonia production and pulling the EU back into the import market it was trying to exit.
The price transmission has already happened. Urea landing at New Orleans jumped 17% soon after the war began, and forward contracts to buy it later rose 35% in a two-week span. QatarEnergy's own Ras Laffan facility halted sulphur, ammonia, and urea production entirely after a drone strike forced it to suspend LNG output — removing roughly a tenth of global urea supply from the market at the worst possible moment: the Northern Hemisphere's spring planting season, the annual peak in nitrogen demand.
Where Does the World Turn — and How Far Does That Get It?
A handful of alternative pools exist: Russia, Trinidad, Nigeria, Indonesia, and US Gulf Coast producers riding cheap shale gas. But each has a ceiling.
• China, traditionally a swing exporter, has kept urea export restrictions in place to protect its own farmers, and has separately extended phosphate export curbs through the end of August 2026 — removing a second major buffer just as Gulf supply wobbles.
• Egypt, often cited as an alternative Middle East source, is itself compromised: its fertilizer production depends heavily on natural gas supplies that are themselves disrupted by regional instability.
• New capacity is coming, but slowly. The International Fertilizer Association's own outlook has 2026 nitrogen capacity rising only about 4% over 2024 — nowhere near enough to offset a Gulf shortfall, and new plants take years, not months, to permit and build.
• There are no strategic international fertilizer stockpiles, unlike oil's Strategic Petroleum Reserve. When the tap is cut, there is no buffer tank to draw down.
The Stickiness Problem: Once a Buyer Moves, They Don't Fully Move Back
This is the part of the story that doesn't get enough attention. Fertilizer buyers — governments, cooperatives, state trading agencies — do not re-tender every month based on spot price. India runs annual government tenders. Countries like India and Pakistan have been locking in multi-year contracts with Iran, Qatar, and Oman to secure discounted forward pricing — but the same logic applies in reverse once those relationships are broken by unreliability.
A buyer burned by a missed shipment during spring planting does not forget it at the next tender. Contracts get rewritten with new counterparties, new payment terms, new war-risk insurance clauses. Once Indian, Australian, or African buyers build fresh relationships with Russian, North African, or North American suppliers to plug a wartime gap, switching back to the pre-crisis Gulf-dominant pattern involves real transaction costs — new logistics chains, new blending infrastructure, new trust. We saw this exact stickiness play out after Russia's invasion of Ukraine reshaped grain and fertilizer flows; four years on, many of those substitution patterns never fully reverted, even after shipping lanes reopened. Hormuz 2026 risks doing the same thing to nitrogen fertilizer trade — permanently trimming the Gulf's share of a market it has dominated for two decades, right as it also loses share of oil and LNG revenue for the same reason.
And Then El Niño Arrives on Cue
If the fertilizer shock were happening in isolation, it would still be serious. It isn't happening in isolation. NOAA's Climate Prediction Center has moved to a full El Niño Advisory, with the event expected to strengthen through the end of the year and a 97% chance of persisting through early spring 2027. The IRI/Columbia forecast plume now assigns roughly 98% probability of El Niño through early 2027, with model consensus pointing to a strong-to-very-strong event peaking around November 2026 to January 2027.
The agricultural fingerprint of a strong El Niño is well documented and unfavourable in exactly the places least able to absorb another shock: India's own meteorological department has already projected the 2026 monsoon at 92% of average rainfall, and the Greater Horn of Africa and South Asia are both being flagged for below-normal rainfall through their critical growing seasons. Layer a fertilizer-constrained planting season on top of a moisture-constrained growing season, and the compounding is not additive — it's multiplicative. Lower nitrogen application depresses yield potential per hectare; a poor monsoon or drought then caps whatever yield that reduced nitrogen could have delivered.
The risk now unfolding in real time: an El Niño-driven food shock coinciding with fertilizer and shipping disruption out of the Persian Gulf — not as a hypothetical, but as the base case.
The Bottom Line
Diplomacy has many tools for an angry man — sanctions relief, security guarantees, investment deals, ceasefire frameworks, all of which have been tried, broken, and retried around Hormuz these past five months. A hungry man responds to exactly one instrument: food on the table.
Governments negotiating over transit tolls and naval escorts should remember that the second-order casualty of this conflict is not measured in barrels or freight rates — it's measured in nitrogen not applied to a hundred million smallholder plots, in corn and soybean yields quietly trimmed across the American Midwest, and in a monsoon that has already been told, months in advance, to disappoint South Asia.
The Gulf's ships may eventually sail freely through Hormuz again. Whether the world's fertilizer trade — and the farmers and consumers eleven steps downstream of it — ever fully sails back to where it was before is a very different question.
