- Abstract
The article presents a study on the life-cycle assessment of net greenhouse-gas flux for bioenergy cropping systems in Pennsylvania. The study aims to quantify all elements to determine the effect of several bioenergy cropping systems on greenhouse-gas emissions. It was found out that the major sources of greenhouse-gas fluxes associated with crop production, are soil nitrous oxide emissions, soil carbon dioxide, methane fluxes and carbon dioxide emissions connected with agricultural inputs and farm equipment operations. The study used the DAYCENT biogeochemistry model to assess soil greenhouse-gas fluxes and biomass yields for corn, soybean, alfalfa, hybrid poplar, reed canarygrass and switchgrass as bioenergy crops.
