Net energy of cellulosic ethanol from switchgrass
Improved genetics and agronomics may further enhance energy sustainability and biofuel yield of switchgrass and improve net energy and economic costs based on known farm inputs and harvested yields. Expand
Chemical composition and response to dilute-acid pretreatment and enzymatic saccharification of alfalfa, reed canarygrass, and switchgrass
Alfalfa stems, reed canarygrass, and switchgrass; perennial herbaceous species that have potential as biomass energy crops in temperate regions; were evaluated for their bioconversion potential asExpand
Farm-Scale Production Cost of Switchgrass for Biomass
The economic potential of cellulosic biomass from switchgrass has heretofore been evaluated using estimates of farm costs based on extrapolation from experimental data and budget estimates. TheExpand
Soil Carbon Storage by Switchgrass Grown for Bioenergy
Life-cycle assessments (LCAs) of switchgrass (Panicum virgatum L.) grown for bioenergy production require data on soil organic carbon (SOC) change and harvested C yields to accurately estimate netExpand
Biomass-Bioenergy Crops in the United States: A Changing Paradigm
The world energy paradigm is changing from one based on petroleum to one based on a mixture of energy platforms. This change is precipitated by a finite petroleum supply, an expanding global demand,Expand
Quantifying Actual and Theoretical Ethanol Yields for Switchgrass Strains Using NIRS Analyses
Quantifying actual and theoretical ethanol yields from biomass conversion processes such as simultanteous saccharification and fermentation (SSF) requires expensive, complex fermentation assays, andExpand
Soil Carbon Sequestration by Switchgrass and No-Till Maize Grown for Bioenergy
Net benefits of bioenergy crops, including maize and perennial grasses such as switchgrass, are a function of several factors including the soil organic carbon (SOC) sequestered by these crops. LifeExpand
Managing and enhancing switchgrass as a bioenergy feedstock
The United States Department of Energy (DOE) has identifi ed switchgrass (Panicum virgatum L.) as a viable perennial herbaceous feedstock for cellulosic ethanol production. Although switchgrassExpand
Establishment Stand Thresholds for Switchgrass Grown as a Bioenergy Crop
Results from the 10 field, three-state study indicated that establishment year stand frequency level of 40% or greater, determined by a frequency grid, can be considered an establishment yearStand threshold for establishment success and subsequent post-planting year biomass yields for switchgrass.

Fire and grazing effects on wind erosion, soil water content, and soil temperature.
Despite poor growing conditions following fire and heavy selective grazing of burned patches, no blowouts or drifts were observed and the effects of patch burning and grazing on wind erosion, soil water content, and soil temperature in sand sagebrush mixed prairie were quantified. Expand
