Study Shows Midwest Corn and Soybean Production to Move North with Warming Temperatures

A study by Pennsylvania State University researchers evaluated more than three decades of crop yield and weather data to predict that warming in the Midwest will cause the best corn and soybean growing area to move north. The study concluded that if warming conditions continue, within 50 years the best conditions for corn and soybean production will shift from Iowa and Illinois to Minnesota and the Dakotas. Researcher Armen Kemanian explains, “It doesn’t mean that Iowa will stop producing crops, but it might mean that Iowa farmers adapt to a warmer climate producing two crops in a year or a different mix of crops instead of the dominant corn-soybean rotation. The changes are likely to be gradual, and farmers and the supply chain should be able to adapt. But things will change.”
