Winter Biomass Yield, Year-Round Elemental Concentrations of 'Kanlow' Switchgrass, and Associated Soil Nutrients in a Zero Input Environment
(Oklahoma State University, 2010-05-01)
Switchgrass (Panicum virgatum L.) is a warm-season perennial species native to North America. It was selected by the U.S. Department of Energy (DOE) as the model herbaceous species for the development as a cellulosic ...
Land management practices on belowground carbon in the ecosystem transitional zone in the south-central Great Plains
(2022-07)
The mesic grasslands in the Great Plains of the USA have a great capacity to sequester atmospheric CO2 into soil. Over 5.2 million hectares of such grasslands in the southern Great Plains are “go-back” lands; areas that ...
Effect of Switchgrass Maturity on Ethanol Production via Simultaneous Saccharification and Fermentation
(Oklahoma State University, 2014-05-01)
Switchgrass has been selected as a substrate to produce ethanol. One method of producing ethanol from switchgrass is through pretreatment followed by saccharification and fermentation. The harvest date of switchgrass could ...
Switchgrass Solution: Enhancing Above- and Belowground Ecosystem Services Through Low-input High-diversity Biofuels
(Oklahoma State University, 2013-12-01)
It has been suggested that native prairie species such as switchgrass (Panicum virgatum) can provide a sustainable, low-input biofuel feedstock, while at the same time sequestering large amounts of soil carbon. Perhaps the ...
Devolatilization Characteristics of Cellulose, Hemicellulose, Lignin and the Selected Biomass During Thermochemical Gasification: Experiment and Modeling Studies
(Oklahoma State University, 2012-05-01)
Pyrolysis and gasification are two promising thermochemical conversion technologies for conversion of biomass into fuels, chemicals and power. Devolatilization is the first major process that occurs in biomass gasification ...
Butanol production from switchgrass using novel strains of Clostridium beijerinckii
(2020-05)
Biobutanol is a promising fuel that can be blended with gasoline and improve its octane number. Biobutanol has been produced from corn starch and molasses via acetone-butanol-ethanol (ABE) fermentation. However, the increase ...
Quantifying Selfing and Outcrossing Fertility in Lowland Swtichgrass Populations Using Ssr Markers
(Oklahoma State University, 2012-12-01)
Switchgrass (Panicum virgatum L.), a native C4 perennial species, is being developed as a major cellulosic crop for biofuel feedstock production in the U.S. However, no information is available on mating behavior of plants ...
Parameterization and Application of the Aquacrop Model for Simulating Bioenergy Crops in Oklahoma
(Oklahoma State University, 2012-07-01)
The objective of this study was to parameterize the AquaCrop model for two bioenergy crops, switchgrass and forage sorghum, using field measurements from Stillwater, Oklahoma in 2011. The parameterized model was then ...
Economic and Environmental Tradeoffs from Switchgrass and Ethanol Production (A Case in Oklahoma)
(Oklahoma State University, 2012-07-01)
In this study IMPLAN 2009 economic data, CEDA 4.41 environmental data and other data sources are used to determine the economic and environmental impact associated with switchgrass based ethanol production in Oklahoma. The ...
Developing a Budget to Plant, Harvest, and Transport Switchgrass
(Oklahoma State University, 2009-12-01)
If there is any hope of moving away from fossil fuels, and towards renewable alternatives, a comprehensive economics analysis of the problem must be performed. This study is the first step in a larger economic analysis ...
