Carbon dioxide and water fluxes from switchgrass managed for bioenergy production

چکیده
Switchgrass (Panicum virgatum L.) is an important bioenergy crop with the potential to provide a reliable supply of renewable energywhile also sequestering C in the soil. The purpose of this studywas to quantify CO2 fluxes during the establishment and early production years of a young switchgrass stand in the northeastern USA. Switchgrasswas sown in June 2004 and daily CO2 fluxesweremeasured for four years. Grossprimaryproductivity (GPP) varied little amongyears, but ecosystemrespiration (Re) decreasedover

The influence of drought and heat stress on long-term carbon fluxes of bioenergy crops grown in the Midwestern USA.
Perennial grasses are promising feedstocks for bioenergy production in the Midwestern USA. Few experiments have addressed how drought influences their carbon fluxes and storage. This study provides a direct comparison of ecosystem-scale measurements of carbon fluxes associated with miscanthus (Miscanthus × giganteus), switchgrass (Panicum virgatum), restored native prairie and maize (Zea mays)/...
متن کاملCarbon and nitrogen dynamics in bioenergy ecosystems: 1. Model development, validation and sensitivity analysis
Biofuel made from conventional (e.g., maize (Zea mays L.)) and cellulosic crops (e.g., switchgrass (Panicum virgatum L.) and Miscanthus (Miscanthus 9 giganteus)) provides alternative energy to fossil fuels and has been considered to mitigate greenhouse gas emissions. To estimate the large-scale carbon and nitrogen dynamics of these biofuel ecosystems, process-based models are needed. Here, we d...
متن کاملLife-cycle assessment of net greenhouse-gas flux for bioenergy cropping systems.
Bioenergy cropping systems could help offset greenhouse gas emissions, but quantifying that offset is complex. Bioenergy crops offset carbon dioxide emissions by converting atmospheric CO2 to organic C in crop biomass and soil, but they also emit nitrous oxide and vary in their effects on soil oxidation of methane. Growing the crops requires energy (e.g., to operate farm machinery, produce inpu...
متن کاملThe biogeochemistry of bioenergy landscapes: carbon, nitrogen, and water considerations.
The biogeochemical liabilities of grain-based crop production for bioenergy are no different from those of grain-based food production: excessive nitrate leakage, soil carbon and phosphorus loss, nitrous oxide production, and attenuated methane uptake. Contingent problems are well known, increasingly well documented, and recalcitrant: freshwater and coastal marine eutrophication, groundwater po...
متن کاملCan the Results of Biodiversity-Ecosystem Productivity Studies Be Translated to Bioenergy Production?
Biodiversity experiments show that increases in plant diversity can lead to greater biomass production, and some researchers suggest that high diversity plantings should be used for bioenergy production. However, many methods used in past biodiversity experiments are impractical for bioenergy plantings. For example, biodiversity experiments often use intensive management such as hand weeding to...
