USDA's Proposal To Move Corn And Soybean Seed Banks Puts Research At Risk, Experts Say

May 19, 2026

By Abigail Bottar

The U.S. Department of Agriculture wants to move two of the nation’s most important seed banks from the University of Illinois Urbana-Champaign — even as some experts raise concerns that change could harm corn and soybean research.

The Maize Genetics Cooperation Stock Center includes 100,000 corn stocks representing genetic mutants, some that were collected as long as 100 years ago and are irreplaceable. The National Soybean Germplasm Collection is the only public soybean seed bank in the country and holds nearly the entire crop’s genetic diversity.

Samples from the collections at the University of Illinois are shipped to scientists around the world who are studying crop yield and disease resistance.

“Colleagues in Europe and Africa and Asia and Latin America, they also contribute to this resource and they also use that resource a lot,” said University of Illinois crop sciences professor Martin Bohn, who uses the maize stock center for his research.

Both collections have been housed on the university’s campus for decades, but the USDA is proposing moving the maize center to Ames, Iowa, and the soybean collection to Columbia, Missouri.

Video: Our Own On-Farm Research Is the Best Source - Managing White Mold in Northeast Nebraska

If you assumed Nebraska was too hot and dry for white mold to be a problem in soybeans, think again.

This week we're featuring Galen Samuelson, a farmer and dealer from Wakefield, Nebraska, who knows all too well how devastating white mold can be.

"We don't have it consistently every year, but with our temperature and humidity, it can hurt us quite bad," Samuelson says. Looking for alternatives, he explains, "What I like about Heads Up is that it's non-harmful to the beneficial fungal colonies in the soil." Galen has been using Heads Up for several years now, after first hearing about it through a small ad in a regional newspaper. Watch below to hear about his journey.

When asked to write about Samuelson Seed, Galen said the following:

"Samuelson Seed is a 4th-generation, family-based company. It started with my grandfather, and I'm now starting to pass the torch to my son, Caleb."

"In the early 1990s, I started working with a company whose focus was on plant and soil health before those benefits were widely known. I've continued to keep plant and soil health the main focus in our farming operation decisions."
