摘要：The share of corn used in ethanol production has been growing rapidly. USDA predicts that more than 30 percent of the corn crop will be used for ethanol production in 2009/2010. Expanded corn acreage contributes to the application of more fertilizer and is likely to introduce a larger volume of nutrients into the environment. This study found that an increase in ethanol production is consistent with a significant increase in quality-adjusted fertilizer use in selected corn states.
