Fertilizer Fight Heats Up As Prices Soar and Survey Points to Bigger Price Risks in 2027

Fertilizer market volatility is once again taking center stage as geopolitical tensions disrupt global supply lines and push input costs sharply higher. Not only did President Donald Trump take to social media to warn of ‘price gouging,’ but Agriculture Secretary Brooke Rollins also posted on X Monday, specifically expressing frustration over Mosaic’s response to farmers.

While Rollins and USDA Under Secretary Stephen Vaden have raised concerns over fertilizer prices this year, the president posted on Truth Social over the weekend that he is closely monitoring fertilizer prices and pledged support for American farmers.

Trump said Saturday on his Truth Social platform he is “watching fertilizer prices CLOSELY” during what he described as the US “FIGHT FOR FREEDOM in Iran”, adding that the administration “will not accept PRICE GOUGING from the fertilizer monopoly”.

On Monday, Rollins posted on X, saying she was “So disappointed in this response” from Mosaic, “especially as you decide to idle two fertilizer production facilities, removing 1 MMT of supply from the world market.”

Mosaic announced last week the decision to shut down major phosphate operations in Brazil, a move the that will cut production, reduce jobs, and signal a *strategic shift in how the fertilizer giant deploys its capital.

Mosaic Company announced Thursday it will idle two phosphate facilities in Brazil as part of a broader effort to cut costs and shift capital. Mosaic expects idling of the facilities to reduce annual phosphate production by approximately 1 million tonnes. CEO Bruce Bodine says the decision reflects what he calls a disciplined focus on long-term returns.

Mosaic and Simplot have also been in the cross hairs of the push to remove countervailing duties on Moroccan phosphate. Groups like the National Corn Growers Association (NCGA) claim the CVDs are costing U.S. agriculture $1 billion each year.

The CVDs on Moroccan phosphate were put into place by the International Trade Commission (ITC) in 2021. As the sunset review begins, more than 50 state grower groups including the Texas Corn Producers Association, sent a letter to the U.S. Department of Commerce and the ITC to revoke the countervailing duties on imported phosphate fertilizers from Morocco and Russia.

In separate filings by Mosaic and Simplot to the ITC and the Department of Commerce, both companies said the continuation is necessary to maintain a “level playing field.”

In a written response to Farm Journal, Mosaic said:

“American farmers depend on a strong domestic fertilizer industry, which in turn depends on strong enforcement of U.S. trade laws that ensure a level playing field. Mosaic is proud to support U.S. agriculture with high-quality, reliable products produced here at home.”

Iran War’s Current Impact on Fertilizer Prices

The message from the Trump adminstration comes as tensions escalate in the Strait of Hormuz, where the United States is weighing a potential full naval blockade. Ship traffic through the critical waterway has already dropped from roughly 135 vessels per day to the single digits. A complete shutdown could halt flows entirely, further increasing fertilizer prices.

The stakes are high as roughly one-third of global fertilizer shipments move through the strait, and the disruption is already sending prices higher, up more than 40% compared to a year ago.

Market data shows the impact Iran is having on already high fertilizer prices. According to StoneX analyst Josh Linville says in the six weeks since the war started:

• Urea prices have surged by $230 per ton, a 49% increase
• UAN is up $145 per ton, or 38%
• Anhydrous ammonia has climbed $245 per ton, a 32% jump.
• In contrast, corn prices have barely responded, rising just two cents, or about half a percent. The divergence is putting additional pressure on farm margins.

DOJ Probe Into Fertilizer Costs Seeks Input From Farmers

The Trump administration is asking farmers to help provide information as part of an ongoing U.S. Department of Justice investigation into elevated costs for fertilizer, machinery and other key agricultural inputs, according to reporting from Bloomberg.

Bloomberg reported the effort is aimed at gathering more on-the-ground data as regulators examine whether fertilizer producers may have coordinated to raise prices. The DOJ investigation was first reported in early March, when Bloomberg said federal officials had begun looking into whether fertilizer companies engaged in price coordination.

According to the Bloomberg report, Vaden said he has already met with officials at both the Department of Justice and the Federal Trade Commission to discuss potential lines of inquiry. He also noted that farmers could play a key role in the process.

Vaden said farmers “have a lot of information that might be relevant to these investigations.”

Bloomberg previously reported in early March that the Department of Justice is investigating whether fertilizer producers colluded to increase prices.

Speaking at the North American Agricultural Journalists’ annual conference in Washington on Monday, Vaden encouraged farmer participation in the probe, emphasizing confidentiality protections.

“We need farmers to help provide us with that information on a confidential basis, so that that can help inform the investigations that are ongoing,” Vaden said, according to Bloomberg. “I think we will have a mechanism in order to help encourage that exchange of information.”

NCGA Surveys Show Not All Farmers Have Fertilizer Secured for 2026

Against that backdrop, along with fertilizer prices climbing even higher in the six weeks after the conflict started with Iran, new surveys results from NCGA highlight how those market pressures are translating to on-farm realities.

Krista Swanson, chief economist for NCGA, says the organization conducted the survey to better understand fertilizer availability from the farmer perspective. Ag Secretary Rollins has told mainstream media that 80% of farmers have fertilizer locked in for 2026, but NCGA data contradicts that figure.

“We’re hearing that number being thrown around too, which is why we really wanted to find out directly from farmers what the status is for them,” Swanson says.

A Significant Gap in Fertilizer Readiness

The surveys show that only 60% of farmers report having their nitrogen fully purchased or secured for the 2026 growing season, while 64% say the same for phosphate. That leaves a sizable portion of producers still working to lock in supplies.

“When you think about over 500,000 corn farmers in the U.S., this isn’t a small number,” Swanson says. “Our survey results indicate that over 200,000 farmers still need at least some fertilizer for this year.”

Nitrogen remains a critical input for corn production and is closely tied to yield potential. Any shortfall, whether driven by availability or cost, can directly affect productivity and profitability.

Younger Farmers Feeling the Pressure Most

The survey also points to uneven impacts across the farm sector, with younger farmers facing greater challenges in securing fertilizer.

Swanson says younger producers reported having more nitrogen left to purchase compared to older farmers.

“You think about younger farmers that have less capital already built up in their business, maybe tighter cash flow needs because of their equity position,” she says. “This does seem to have a disproportional impact on younger farmers.”

That dynamic raises concerns about financial strain among newer operations in a high-cost environment.

Corn Acres Likely Stable, But With Reduced Inputs

Despite the challenges, most farmers are not planning to reduce corn acreage. The survey found that 80% of respondents expect to maintain their planned acres.

At the same time, fertilizer application rates may fall short. Half of the farmers surveyed say they do not expect to apply their full amount of fertilizer.

“Pairing these two together, it seems to me like we are still going to see a lot of corn acres get planted,” Swanson says. “But those corn acres will have less fertilizer than maybe what they would have otherwise had.”

That combination could limit yield potential if input reductions become widespread.

Growing Concern Shifts to 2027

While fertilizer availability remains a concern for 2026, attention is already turning to the next crop year. Fertilizer purchasing follows a rolling cycle, and planning for 2027 will begin soon.

Survey responses show that for every one farmer more concerned about fertilizer price and availability for 2026, nearly two are more concerned about 2027.

“So farmers are concerned as we look ahead to next year,” Swanson says.

The shift reflects uncertainty about how long supply disruptions and elevated prices will persist.

Supply Chain Recovery May Take Time

Even if geopolitical tensions ease, relief may not come quickly. Swanson notes that the fertilizer market is still dealing with production disruptions and supply chain backlogs.

“A short-term ceasefire has limited immediate impact on this ongoing fertilizer crisis for farmers,” she says. “Even when a permanent end to the situation is reached, we’re still looking at recovery from supply chain backlogs and halted production that could take a long time to recover from.”

Damage to key inputs such as liquid natural gas and sulfur production could take years to repair, keeping pressure on supply.

A Tightening Outlook

The NCGA survey underscores a challenging environment for corn producers. Most acres are expected to be planted this year, but not all will receive optimal fertilizer applications. At the same time, concern is building for 2027 as farmers look ahead to the next purchasing cycle.

For many producers, the issue is no longer just securing fertilizer for this season. It is navigating a period of sustained uncertainty that could shape production decisions, costs, and risk management strategies across the U.S. corn sector.

Longstanding Concerns Over Market Concentration

In September 2025, USDA and the U.S. Department of Justice signed a Memorandum of Understanding, committing both agencies to jointly examine high and volatile input costs, which included fertilizer, by scrutinizing competitive conditions in agricultural markets and enforcing antitrust laws, particularly around price setting and market concentration.

While geopolitical tensions are the latest driver of volatility, many farm groups argue the root of the problem runs deeper. Matt Perdue, president of the North Dakota Farmers Union, says ongoing federal investigations into fertilizer pricing must lead to meaningful action.

“We appreciate the administration’s investigations into input costs,” Perdue says. “But investigations don’t do anything if they’re not followed by enforcement, and they don’t do anything if we don’t learn what came out of those investigations.”

Groups like the Texas Corn Producers Association have been raising concerns about fertilizer market concentration for years. Texas farmer Dee Vaughan says the organization began studying the issue in 2020, working with the Agricultural and Food Policy Center at Texas A&M to examine pricing trends.

“We’ve been very concerned about all of our input costs, but specifically fertilizer, because it’s the one that just keeps going up almost exponentially,” Vaughan says.

He adds those studies found a shift in how fertilizer prices are determined. Historically tied closely to natural gas costs, the study found nitrogen fertilizer pricing began tracking corn prices more closely after 2010, a change Vaughan says reflects deeper structural issues.

According to Vaughan, the small number of firms controlling the market have the data and market awareness to price inputs based on farmers’ revenue potential, rather than production costs.

“They all have economists on staff,” Vaughan says. “They know exactly what our costs are, what our income is, and they’re able to extract value based on what they see as the gross income of a farmer. It’s not based on cost of production any longer.”
