NASHVILLE, TENN. (RFD NEWS) — The U.S. Department of Justice (DOJ) has launched an antitrust investigation into fertilizer pricing practices, a move closely watched by farmers facing elevated input costs ahead of planting season.

According to reporting by Bloomberg, the DOJ’s Antitrust Division is examining whether major producers — Nutrien, Mosaic, CF Industries, Koch Industries, and Yara International — colluded to raise prices on U.S. farmers. Together, the firms represent a dominant share of nitrogen, phosphate, and potash supply in the United States.

Farm organizations have raised concerns about fertilizer market concentration for years, and industry pressure has intensified recently as margins tighten across crop agriculture. USDA Deputy Secretary Stephen Vaden earlier described Nutrien and Mosaic as a “duopoly,” while groups including the Texas Corn Producers Association and Iowa Corn Growers Association have urged federal regulators to review pricing practices.

For producers entering the spring planting season, fertilizer costs remain a key financial pressure even as commodity prices soften. The investigation could shape future input pricing and competition depending on its findings.
