Urea Prices Up 32%, A Million Tons Stranded: Hormuz Blockade Threatens 2026 Harvest

US urea prices jumped 32% in a single week. Nearly a million metric tons of fertilizer sit stranded in the Persian Gulf. Spring planting starts in six weeks.

Nobody's talking about it.

Oil hits $126 a barrel and markets watch the Strait of Hormuz. But a quieter crisis is building — one that won't show up until autumn, when the 2026 harvest comes in short.

The invisible chokepoint

Oil moves through Hormuz. Everyone knows that. Fertilizer moves through there too. Most people don't.

Gulf-region countries account for nearly half of globally traded urea exports and roughly 30% of ammonia exports. Natural gas — the feedstock for nitrogen fertilizer — comes from the same place.

Iran mined the strait 17 days ago. Shipping stopped. The fertilizer didn't just get expensive. It got stuck.

Major producers declared force majeure. Urea hit $591 per tonne, up 25% since the war began. A Canadian farmer who bought in December would pay $32,070 more today — if he could find supply at all.

The clock is biological, not political

Fertilizer isn't like oil. You can't wait it out.

Spring planting in North America runs late March through May. Fertilizer goes down before or during early growth — not after. Ships take weeks to reach US ports from the Gulf. Then barges, trucks, and rail move it to farmland. By the time it arrives, the window may be shut.

"Even if the Strait of Hormuz does open soon, restarting production and transport for fertilizers could take weeks — weeks that Northern Hemisphere farmers do not have," warns the Carnegie Endowment.

The American Farm Bureau Federation wrote to Trump: "Without strategically prioritizing the delivery of critical farm inputs like urea, ammonia, nitrogen, phosphate, the United States risks a shortfall in crop production." They called it a national security threat.

Three bad options

Farmers facing a 30% price spike and uncertain supply can:

Under-apply. Use less fertilizer. Agronomists warn that cutting nitrogen and phosphate by more than 10% could drop corn and wheat yields 5% to 8% globally. That tightens grain stocks and pushes food prices higher by autumn. Delay. Wait for prices to drop or supply to stabilize. But planting windows are narrow. Late planting means lower yields. Miss the window and you lose the season. Switch crops. Plant something that needs less fertilizer. But rotations are planned months ahead. Switching mid-season disrupts entire supply chains.

Seth Meyer, former USDA chief economist: "A bad decision this year could be pretty costly."

Countries already rationing

Bangladesh closed all universities on March 9. Not because of COVID. Not unrest. To save fuel.

The country imports 95% of its energy. With Hormuz closed, it's rationing fuel, advancing Eid-al-Fitr holidays, turning off festival lights, and stationing troops at oil depots to stop hoarding.

Pakistan moved to a four-day work week and closed schools. Sri Lanka did the same. Thailand's commerce minister is preparing "special scenarios" for prolonged disruptions.

These aren't minor adjustments. They're emergency measures to stretch supplies that were never meant to last this long. Their farmers are already deciding which fields to plant and which to leave fallow.

Why Russia can't fill the gap

Russia's the world's largest fertilizer exporter. Can't they ship more? No.

Russian producers told Reuters they've hit capacity limits. They can't ramp up fast enough to replace what's trapped in the Gulf. They're also protecting their own market — Russia approved export quotas to preserve supplies for Russian farmers.

Europe's already feeling it. EU nitrogen fertilizer imports dropped to 179,877 tons in January 2026, down from 1.18 million a year earlier. European farmers are competing for shrinking supply like everyone else.

The harvest that hasn't failed yet

Fertilizer crises are invisible until they're not.

Fields look fine right now. Farmers are making plans. Markets price in oil disruptions, not food disruptions.

But if spring planting gets disrupted — if farmers under-apply, delay too long, or can't find supply — the impact hits in September and October, when yields come in 5% to 8% below forecast.

By then it's too late. You can't fertilize a crop that's already growing. You can't replant a season that's passed.

The International Fertilizer Development Center estimates a sustained Gulf disruption could cut Nigerian maize yields 15% to 25%. Similar drops would hit every region dependent on imported fertilizer. Food prices spike. Grain reserves deplete faster. Import-dependent countries face shortages.

And people will ask: why didn't anyone see this coming?

What needs to happen now

The Farm Bureau gave the White House seven recommendations. The core message: treat fertilizer as a strategic priority, not an afterthought.

That means prioritizing fertilizer shipments if Hormuz reopens, releasing domestic reserves, fast-tracking alternative supply routes, coordinating with allies on distribution, and supporting farmers with financing while prices stay elevated.

None of this fixes the immediate supply crunch. But it buys time and cuts the risk of catastrophic yield loss.

The pattern repeating

This isn't new. In 2022, the Ukraine war disrupted Russian and Belarusian fertilizer exports and sent gas prices soaring. Food prices spiked. Farmers in Côte d'Ivoire, Kenya, Nigeria, and South Africa cut fertilizer use. Yields dropped.

That crisis took months to surface in food prices. By then, the damage was done.

Different war. Same chokepoint. Same lag between disruption and impact.

The difference: timing. Hormuz closed right as Northern Hemisphere farmers need to lock in supply. The window is six weeks, maybe eight.

Strait closed through April? Spring planting gets compromised. Through May? The 2026 harvest shrinks. Longer? Global food security event.

What this means

You can stockpile oil. You can release reserves. You can reroute ships and find alternative suppliers.

You can't stockpile a growing season.

The crisis isn't invisible anymore. It's just quiet. And it's on a hard deadline that no diplomacy, no military operation, no market intervention can extend.

April is six weeks away. The ships are stuck. The farmers are waiting.

The 2026 harvest is already being decided — whether anyone's paying attention or not.
