The almond trees in Tulare County don’t care about geopolitics. They need water, nutrients, and diesel-powered equipment to bring their harvest to market — the same things they’ve always needed. But in March 2026, every single one of those essentials became dramatically harder to afford. And the people who tend those trees — the multi-generational farming families of California’s Central Valley — are staring down yet another crisis in what has become an unrelenting decade of them.
When U.S. and Israeli forces launched joint airstrikes against Iranian military infrastructure on February 28, 2026, the immediate focus fell on oil markets, defense strategy, and diplomatic fallout. What got far less attention, at least in the early days, was how a war thousands of miles from Fresno would reach directly into the pockets of American farmers — and how California’s agricultural sector, the largest in the nation, would bear the heaviest burden.
This is the story of an industry already on its knees being asked to absorb one more blow. And it raises a question that nobody in Washington seems eager to answer: how much more can these farmers take?
The Backbone Was Already Cracking
To understand why the Iran war landed so hard on California agriculture, you have to understand what came before it.
California’s farm economy is enormous. The state’s agricultural output topped $60 billion for the first time in 2024, a milestone that sounds triumphant until you look beneath the headline number. That record masked deep and widening fractures. Commodity prices for many staple crops had been depressed for three consecutive years. Farm debt across the country climbed to record highs in 2025. Bankruptcies were ticking upward for the third straight year, and more than half of American farmers surveyed by Farm Journal reported feeling worse off than they had twelve months earlier.
California’s Agriculture Secretary Karen Ross compared the current conditions to the hardships of the 1980s farm crisis — and suggested that the combination of climate uncertainty, regulatory pressure, labor shortages, and shrinking margins has actually made the present situation more difficult.
Then came the tariffs.
The renewed U.S.-China trade war of 2025 hit California’s specialty crop growers with devastating precision. When China retaliated against new American tariffs with steep duties of its own, the damage was immediate and staggering. A study by economists at the University of California and North Dakota State University documented the wreckage: the total value of California’s top 13 agricultural exports to China collapsed by 64%, a loss of nearly $1 billion in a single year.
The tree nut sector was gutted. Pistachio shipments to China dropped roughly 84%. Almond exports fell about 77%. Counties that anchored their economies to agriculture absorbed enormous hits — Fresno County alone lost an estimated $246 million in export value, while Kern County saw losses around $238 million.
These weren’t abstract numbers. They translated into shuttered processing facilities, idle trucks, and families wondering whether a farm that had been profitable for three generations could survive a fourth.
And the pain wasn’t limited to the China trade. Canada — the destination for 35% of California wine exports — launched a broad “don’t buy American” campaign in response to broader tariff threats. The European Union imposed its own retaliatory duties. The almond industry, which supports an estimated 110,000 jobs and contributes $4.7 billion in exports, faced projected losses of up to $875 million from multiple retaliatory tariff fronts.
Rebuilding those lost trade relationships won’t be quick. UC Davis agricultural economist Colin Carter warned that regaining trust and market share could take years, possibly decades, and would likely require hundreds of millions of dollars in market development investments. Competitors from Australia, Brazil, and Chile moved aggressively to fill the vacuum, and they aren’t going to hand that market share back voluntarily.
So when the first bombs fell on Iran, California farmers weren’t standing on solid ground. They were already scrambling for footholds on a slope that had been eroding beneath them for years.
The Strait That Connects Everything
The Strait of Hormuz is about 7,500 miles from the Central Valley. Most Californians couldn’t find it on a map. But this narrow waterway at the mouth of the Persian Gulf is one of the most consequential chokepoints in the global economy — and for American agriculture in particular, its closure changed everything overnight.
Roughly one-fifth of the world’s oil passes through the strait under normal conditions. Perhaps even more relevant for farmers, about half the global supply of urea — the most commonly used nitrogen fertilizer on farms worldwide — is shipped through the same passage.
When Iran retaliated against the U.S.-Israeli strikes by effectively closing the Strait of Hormuz, it didn’t just spike oil prices. It severed a critical artery for the fertilizers that feed American farmland.
The International Energy Agency has characterized the disruption as the largest supply shock in the history of global oil markets. And the impact rippled outward with terrifying speed.
Within the first three weeks of the conflict, diesel prices in California surged to an average of $7.26 per gallon. Nationally, diesel crossed the $5.30 mark. For farmers who depend on diesel to run tractors, operate irrigation pumps, and fuel the big rigs that haul their crops to market, the cost increase was immediate and inescapable.
Fertilizer prices followed a similar trajectory. Urea prices jumped roughly 25% since the start of the war, according to analysis by the American Farm Bureau Federation. Anhydrous ammonia — a nitrogen fertilizer critical for the corn crop — spiked from around $843 per ton to $1,000, an 18% increase. And the price for imported urea in its crystallized form climbed by nearly a third, according to FactSet data.
The timing could hardly have been worse. As one agricultural economist at North Dakota State University observed, global fertilizer markets were already extremely tight before the Strait of Hormuz crisis. The aftershocks of Russia’s 2022 invasion of Ukraine had kept fertilizer prices elevated for years. This new disruption landed on top of an already strained system.
Sal Parra Jr., who helps manage his family’s 1,500-acre farm in Fresno County and serves as operations director at a 10,000-acre farming operation in adjacent Merced County, described the dual hit with blunt clarity: California farmers are absorbing higher fertilizer costs and higher fuel costs simultaneously, and every American will eventually pay for it at the grocery store because these commodities are priced on global markets.
Crops Stranded at Sea
The cost squeeze is only half the story. The other half involves California’s products that simply can’t reach their buyers.
California is the nation’s largest agricultural exporting state, and the Middle East is a significant market — particularly for tree nuts. When Iran shut down the Strait of Hormuz, it didn’t just block oil tankers. It paralyzed commercial shipping to ports in the region, including Dubai, one of the Middle East’s biggest trading hubs.
Bill Carriere, a walnut grower in Glenn, California, described the chaos to CBS Sacramento. His farm ships to more than 30 countries, and the Middle East accounts for more than 20% of his business. When the war started, shipments already on the water became stranded. Loads ready for departure were held back. Buyers told him to stop shipping because nobody knew how long the disruption would last.
The California Walnut Board and Commission estimated that 70,000 tons of walnuts — roughly 10% of the billion-dollar sector’s annual production — were either in transit to the Middle East or scheduled for shipment when the conflict erupted. The timing was particularly painful because the walnut industry had been in the middle of a major Ramadan marketing campaign, promoting the nutrient-rich nuts to consumers during the holy month that began on February 19. That promotional blitz had to be scrapped entirely.
The disruption extended beyond ocean freight. Air cargo routes that carry perishable California produce — cherries, strawberries, premium fruits — to Middle Eastern and Asian markets faced war-risk surcharges, higher jet fuel costs, and increased demand for limited air freight capacity as shippers sought alternatives to blocked ocean routes.
Jay Van Rein, acting director of public affairs at the California Department of Food and Agriculture, confirmed that growers and handlers had reported canceled shipments, delayed deliveries, and skyrocketing shipping costs across multiple commodities, including tree nuts, olives, wild rice, and blueberries.
The inventory pile-up creates its own vicious cycle. As product that was destined for the Middle East gets diverted or sits in warehouses, it floods other markets and pushes prices down across the board. Farmers who were already selling on thin margins now face the prospect of selling at a loss — or not selling at all.
A Water Problem That Never Went Away
Layer all of this on top of California’s chronic water challenges, and the full scope of the crisis becomes clear.
Even as the state was officially declared drought-free in early 2026 thanks to a wet start to the water year, farmers in the Central Valley continued to struggle with inadequate water allocations. The gap between what farmers need and what the state’s water infrastructure delivers has been a structural problem for decades, and it’s getting worse.
The Sustainable Groundwater Management Act, or SGMA, is forcing farmers to reduce pumping from wells they’ve relied on for generations. Research from the Public Policy Institute of California suggests that up to 900,000 acres of California farmland could eventually be forced out of production due to water scarcity. The economic fallout from that alone — an estimated $2.5 billion in lost annual farm revenue and up to 50,000 jobs in the Central Valley — would constitute a catastrophe under normal circumstances.
But these aren’t normal circumstances. They’re circumstances where a farmer is simultaneously dealing with a water shortage, skyrocketing diesel costs, unaffordable fertilizer, collapsed export markets in China, stranded shipments in the Middle East, and the lingering damage from years of trade policy whiplash.
Farmers who rely on wells to supplement inadequate surface water deliveries are now paying sharply higher energy costs to run their pumps — costs that were already elevated before diesel prices surged past seven dollars a gallon. It’s the kind of compounding pressure that doesn’t break an industry all at once but grinds it down, season by season, until the economics simply stop working.
The Federal Response Gap
What makes the situation even more frustrating for California’s farmers is the sense that federal relief programs have historically overlooked them.
During the earlier 2018–2019 trade war with China, the USDA distributed $23 billion in Market Facilitation Program payments to cushion the blow for American farmers. California received less than 2% of that total, despite being the largest agricultural state by value. The newer Farmer Bridge Assistance program introduced in 2025 has followed a similar pattern, prioritizing Midwestern row crops — corn, soybeans, wheat — over California’s specialty crops.
That distinction matters enormously. A corn farmer in Iowa and an almond grower in Kern County both suffer when trade policy goes sideways, but the federal safety net was designed with the Midwesterner in mind. California’s diverse, high-value agriculture — the nuts, fruits, vegetables, dairy, and wine that make the state’s farm economy unique — doesn’t fit neatly into aid formulas built around grain and commodity crops.
The California Walnut Board has appealed to state and federal officials for financial support to cover costs associated with stranded shipments and lost market access. The California Department of Food and Agriculture has been gathering impact data across the industry. But as of late March 2026, no targeted relief program for California’s war-affected agricultural sector has materialized.
The White House, for its part, has offered little comfort. When asked about the war’s impact on fertilizer costs, a spokesperson said the impacts were temporary and that “the best is yet to come” for American farmers. The President has called rising fuel costs a “small price to pay” for pursuing the military objectives in Iran, while simultaneously suggesting he wants to wrap up the conflict quickly.
For farmers watching diesel tick past seven dollars, those words ring hollow.
What Comes Next
The most troubling aspect of this crisis is that even its resolution won’t undo the damage.
Agricultural economists warn that even if the Strait of Hormuz were reopened tomorrow, fertilizer prices wouldn’t quickly recover. Gulf suppliers have halted production amid the fighting, and restarting those operations takes time. Supply chains that have been disrupted at this scale don’t snap back into place on command.
Meanwhile, the market share that California farmers have lost — to Chinese retaliatory tariffs, to Middle Eastern shipping disruptions, to competitors in Australia and South America — will be extraordinarily difficult to reclaim. Trade relationships in agriculture are built on years of reliability and trust. They can be destroyed in weeks by forces entirely outside a farmer’s control, and they take decades and hundreds of millions of dollars to rebuild.
Fourth-generation California farmer Andrew Leimgruber, speaking publicly about the crisis in late March, emphasized another layer that often gets lost in the national conversation: California’s regulatory environment effectively doubles his operating costs compared to farmers in neighboring states. The state’s environmental rules, labor laws, and water regulations add overhead that farmers in less regulated states don’t face. When global shocks hit, that regulatory burden becomes the difference between surviving and going under.
The math is getting simple — and brutal. Revenues are down because trade wars closed markets and excess supply is depressing prices. Costs are up because diesel, fertilizer, shipping, and water are all more expensive. Federal relief is slow, limited, and poorly designed for California’s crop mix. And the war adds an entirely new dimension of uncertainty to an industry that was already operating on the thinnest of margins.
Some California farming families who have worked the same land for a century or more are now making the difficult calculation about whether the next generation can afford to keep going. A farm isn’t just a business; it’s a way of life, a community anchor, a piece of family identity. But sentiment doesn’t pay fuel bills, and heritage doesn’t offset a billion dollars in lost exports.
The Grocery Store Reckoning
There’s a final dimension to this story that extends far beyond the Central Valley, and it will land directly on the kitchen table of every American household.
California produces more than half the nation’s fruits, nuts, and vegetables. When California farmers struggle, the effects cascade through the entire food supply chain — from processors to truckers to grocery store shelves. The USDA had already projected that food prices in 2026 would rise more than in either 2024 or 2025, even before the war began. The additional pressure from spiking input costs, disrupted shipping, and falling production will accelerate that trend.
The president of the American Farm Bureau Federation put it simply: when farmers face supply shortages or major price increases, those impacts ripple through the entire food chain. What starts as a seven-dollar gallon of diesel in Fresno eventually becomes a more expensive bag of almonds in Atlanta, a pricier head of lettuce in Chicago, a costlier carton of milk in Miami.
California’s farmers have endured drought cycles, labor shortages, regulatory battles, pandemic disruptions, and the economic whiplash of two trade wars in less than a decade. Each time, they adapted. They diversified markets. They invested in technology. They tightened belts. They survived.
But survival has a cost, and resilience has limits. The Iran war didn’t create California’s agricultural crisis. It walked into one that was already well underway and made it dramatically, perhaps irreversibly, worse.
The almond trees in Tulare County still don’t care about geopolitics. But the families who planted them are running out of ways to pretend that geopolitics doesn’t care about them.
