Growing perennial grasses on the least productive farmland now used for corn ethanol production in the U.S. would result in higher overall corn yields, more ethanol output per acre and better groundwater quality, researchers report in a new study. The switch would also slash emissions of two potent greenhouse gases: carbon dioxide and nitrous oxide.
