U.S. Department of Justice Opens Investigations into U.S. Fertilizer Market
18 March 2026 With U.S. fertilizer prices increasing by up to 33% by some suppliers since February 28, 2026, the U.S. Department of Justice (DoJ) has launched a formal investigation into the domestic fertilizer market, focusing on potential collusion and price gouging that many farmers say are hurting the industry from the ground up. The probe is examining several leading fertilizer companies, including CF Industries, Nutrien, Mosaic, Koch, and Yara, which together represent a substantial portion of U.S. nitrogen fertilizer supply and maintain strong positions in potash and phosphate markets.
“Farmers aren’t asking for anything unreasonable. We’re asking for transparency,” said Eric Tipton, President of the Ohio Corn & Wheat Growers Association and a farmer based in Fayette County, Ohio.
“Fertilizer is one of the most essential tools we rely on to produce crops. Competition in that marketplace has declined dramatically while prices have surged. With fewer options and skyrocketing costs, farmers are hurting and asking serious questions. That’s why we believe the U.S. Department of Justice and USDA should fully investigate what’s happening and make their findings public. Farmers deserve to know whether the system they depend on is functioning fairly.”
Historically, changes in the fertilizer market have occurred gradually since the 1980s, when industry consolidation began reducing the number of fertilizer suppliers serving the U.S. market.
Jeff Pritchard, Chief Executive Officer of Westlink Ag Group, an agricultural consulting firm that advises growers and retailers on crop inputs and farm management, says the scale of consolidation has significantly reshaped the industry.
“Back in 1984, there were 46 nitrogen suppliers. Today, four of them control 75% of the U.S. market,” Pritchard said. “That’s a completely different paradigm, and its impact on fertilizer prices is relevant.”
Meanwhile, U.S. Senator Josh Hawley (R-Mo.) has called for increased scrutiny. In his letter, Hawley wrote: “American farmers should not be exploited by dominant firms using a foreign crisis as cover to impose unjustified price increases, restrict supply, or coordinate market behavior. If firms are using this moment to pad margins at the expense of producers who feed this country, the Department should act swiftly.”
Tipton says the stakes extend beyond the farm gate, as rising input costs eventually filter down to consumers. Maintaining trust between suppliers, farmers, and consumers is essential for a stable U.S. food system.
“Farmers feel the pressure first, but consumers ultimately pay at the grocery store,” Tipton said. “Trust between suppliers and customers is essential. When that trust is broken, it affects not just farm families but the stability of our entire food system.”
While farmers hope for regulatory intervention, Pritchard said the DoJ’s inquiry may have limited impact on fertilizer prices in the immediate term.
“Nothing will really come out of it in terms of price improvement in the short term,” he said. “Farmers will likely lower their expectations for yield, cut their inputs, and seek alternatives — because in a free market, there’s only so much the government can do in short order.”
Pritchard noted that many farmers are already adapting to high fertilizer costs in real time, which could create opportunities for companies offering alternatives such as biostimulants and biofertilizers.
“Growers are very intuitive,” Pritchard said. “They look at their cash flows and say, ‘I might be able to get by with less urea, less phosphate.’ Necessity is the mother of invention, and high costs are opening the door for outright demand destruction and/or the use of biostimulants, stabilizers, and other options. Longer term, this trend on the farm could become the new normal.”
Market observers say global supply chain disruptions and geopolitical events can contribute to fertilizer price volatility. However, structural issues within the domestic market — including limited competition — remain a significant factor driving higher costs for farmers. As Pritchard noted, “in a free market, there’s only so much the government can do in short order.”
The DoJ investigation is expected to explore whether collusion or other anti-competitive practices have influenced pricing in a market vital to U.S. agriculture.
As the inquiry unfolds, farmers and policymakers alike will be watching closely for answers. Tipton emphasized the importance of transparency moving forward.
“Farmers want the facts and a fair marketplace,” he said.
