Like a baseball slugger whose home run totals rise despite missing more curveballs each season, the U.S. Corn Belt’s prodigious output conceals a growing vulnerability. A new Stanford study reveals that while yields have increased overall—likely due to new technologies and management approaches—the staple crop has become significantly more sensitive to drought conditions. The research, published Oct. 26 in Nature Food, uses a novel approach based on wide differences in the moisture-holding capabilities among soils. The analysis could help lay the groundwork for speeding development of approaches to increase agricultural resilience to climate change.
