In the U.S., 52% of irrigated land is used for corn, soybean and winter wheat production. Corn and soybean are two of the country’s most important crops, with 17% of corn production and 12% of soybean production coming from irrigated areas. However, the water used for this irrigation is often unsustainably pumped groundwater. Using groundwater sustainably for agriculture in the U.S. could dramatically reduce the production of corn, soybean and winter wheat.
