ICGA Statement on Fertilizer Pricing Investigation


By Lyndi Allen • March 5, 2026

The U.S. Department of Justice (DOJ) is reportedly investigating whether major fertilizer manufacturers colluded to raise prices in the U.S. market, according to Bloomberg (also found in Farm Progress). The investigation is in the early stages and is being run out of the DOJ antitrust division’s Chicago office.


Only a handful of companies control the supply of most fertilizer in the U.S,. which has raised concern among farmers and government officials. Four industries controlled 75 percent of the market share of nitrogen fertilizer in the U.S. in 2019. Two industries control more than 90 percent of phosphate fertilizer and potash production in the U.S. in 2024.


Upon reading the Bloomberg report of a potential investigation into fertilizer prices, ICGA President and Illinois farmer Mark Bunselmeyer released the following statement: 


“ICGA is encouraged by the formal process to investigate fertilizer prices and provide eventual input cost relief for Illinois corn farmers. Our association has prioritized bringing competition to the fertilizer marketplace for our members as they are squeezed by high costs of production and low commodity prices. We will monitor this report, its findings, and will always advocate for the best interests of our members.”
