Carbon dioxide and water fluxes from switchgrass managed for bioenergy production
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 fo...
متن کاملDeveloping Switchgrass as a Bioenergy Crop*
The utilization of energy crops produced on American farms as a source of renewable fuels is a concept with great relevance to current ecological and economic issues at both national and global scales. Development of a significant national capacity to utilize perennial forage crops, such as switchgrass (Panicum virgatum, L., Poaceae) as biofuels could benefit our agricultural economy by providi...
متن کاملNitrogen use in switchgrass grown for bioenergy across the USA
The effect of nitrogen (N) fertilizer on switchgrass biomass production has been evaluated in a number of locations on a small-plot scale; however, field-scale information regarding switchgrass response to N and N use efficiency (NUE) in different regions of the USA is limited. Switchgrass was planted in South Dakota (SD), New York (NY), Oklahoma (OK), and Virginia (VA) in 2008 and in Iowa (IA)...
متن کاملComparison of corn and switchgrass on marginal soils for bioenergy
Crop residues such as corn (Zea mays L.) stover are viewed as an abundant and inexpensive source of biomass that can be removed from fields to produce bioenergy. Assumptions include that with minimum or no-tillage farming methods, there will be no deleterious production or environmental effects. A long-term field study was established in eastern Nebraska, USA, to compare the switchgrass managed...
متن کاملSwitchgrass yield on reclaimed surface mines for bioenergy production.
The high cost of transportation fuels and the environmental risks associated with acquiring and using nonrenewable energy sources have created a demand for developing renewable bioenergy crops. Switchgrass ( L.), a warm-season perennial grass, is a promising feedstock due to its high biomass production under a wide range of growing conditions and its satisfactory forage quality and chemical com...
