Cellulosic biofuels are intended to improve future energy and climate security. Nitrogen (N) fertilizer is commonly recommended to stimulate yields but can increase losses of the greenhouse gas nitrous oxide (N2O) and other forms of reactiveN, including nitrate.Wemeasured soil N2O emissions and nitrate leaching along a switchgrass (Panicum virgatum)high resolutionN-fertilizer gradient for three years post-establishment. Results revealed an exponential increase in annualN2O emissions that each… CONTINUE READING
