For Your Fields

A collection of resources that arm farmers with research-based information when it’s go time for growing soybeans. Find everything from variety selection tools and new practices to disease and insect management calculators.

“Soybeans are grown in more than 30 states, and navigating all the resources out there can be a full-time job. We’re covering standard topics like planting, seeding rates, pests and diseases. But, we’re also covering newer topics in making decisions around biologicals.”

Tom Frisch, farmer-leader from Dumont, MN
