Corn Growers Tackle Rising Fertilizer Costs

By Lesly McNitt

Spring has sprung in the nation’s capital. The sun is shining. Plants and flowers are blooming. Weekend marathons are happening across the city. Yet the discussions taking place in the halls of power here are a reminder that all is not rosy across the country and around the world.

As the conflict in the Middle East rages on, and the Strait of Hormuz remains all but closed, growers are feeling the pinch as diesel fuel and fertilizer prices climb higher and become harder to attain. But if nothing else, the conflict is also exposing structural problems in the highly concentrated fertilizer industry that plagued growers well before the strait was closed.

America’s corn growers are entering the fourth year of negative returns, and input costs, including fertilizers, have long been too high. The National Corn Growers Association has worked to address these problems by encouraging Congress and the White House to open more domestic and international demand and by launching NCGA’s Input Task Force, which is charged with getting to the bottom of why input costs are so high and developing recommendations that can help address root causes. NCGA has been leading the charge to elevate these issues with the federal government as well.

While we have seen forward movement on many of our policy and regulatory priorities, we continue to hit a brick wall as we have called on U.S. – based fertilizer conglomerates, J.R. Simplot and Mosaic Company, to do their part in addressing higher prices.

What insect threats are Minnesota corn growers facing, and what research is helping farmers stay ahead of them?

At the 2026 MN Ag Expo, University of Minnesota entomologist Fei Yang shared updates on three Minnesota Corn-supported research projects focused on insect monitoring, seed treatments, and pest resistance.

Current work includes statewide monitoring programs that use pheromone, light, and sticky traps to track key pests such as black cutworm, true armyworm, corn earworm, European corn borer, and corn rootworm. Researchers are also evaluating whether high-rate seed treatments provide effective corn rootworm control and studying the development of resistance in European corn borer populations to Bt corn traits.

These projects help researchers better understand pest pressures across Minnesota and provide farmers with practical information to support informed management decisions.
