University of Minnesota researchers project that by the 2040s the most favorable corn and soybean growing region will shift northwest, potentially favoring Minnesota, North Dakota and South Dakota over Iowa and Illinois. Warmer temperatures and longer seasons could help, but heat stress, evapotranspiration and new pests and diseases could limit gains.
Minnesota's growing season has already lengthened by nearly two weeks since the 1950s.
These are long-term projections with no immediate effect on supply or prices. They may matter for future acreage and production patterns in the Corn Belt.
