Nitrous oxide emissions in a landscape transitioning from Conservation Reserve Program grassland to energy crops switchgrass and Miscanthus

A.R. Kemanian, D. Shaha, B.M. Rau, J.P. Kaye, F.R. Montes & P.R. Adler
uture liquid fuel demand from renewable sources may, in part, be met by converting the seasonally wet portions of the landscape currently managed for soil and water conservation to perennial energy crops. However, this shift may increase nitrous oxide (N2O) emissions, thus limiting the carbon (C) benefits of energy crops. Particularly high emissions may occur during the transition period when the soil is disturbed, plants are establishing, and nitrate and water accumulation may favor emissions....
