Grain-based ethanol production has increased dramatically in recent years and with this expansion comes unintended negative water quality impacts.
Scientists evaluated potential impacts of grain- and cellulose-based ethanol on nutrient and animal management as they relate to water quality in US inland and coastal waters.
They recommended advanced conservation measures to minimize N and P losses and suggested a viable cellulosic ethanol industry could reduce grain dependence and provide water quality and other environmental benefits.
