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 ...
Days available for harvesting switchgrass and the cost to deliver switchgrass to a biorefinery
(2007-07)
Scope and Method of Study: The purpose of this study was to estimate the number of suitable field workdays per month in which switchgrass can be harvested in Oklahoma at different probability levels. This study also sought ...
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 ...
Remote sensing application in biomass crop production systems in Oklahoma
(2013-12)
This study was conducted to evaluate the combined effects of nitrogen and cropping systems on biomass yield and quality and to describe the spatial variation of biomass yield, soil carbon and nitrogen within a switchgrass ...
Effects of nutrient sources, harvest frequency, and environmental conditions on switchgrass production and soil properties
(2013-12)
Switchgrass is considered a promising low-input biofuel feedstock. Previous development primarily focused on aboveground production, however, feedstock success will depend on identifying sustainable management practices ...
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 ...
Scenario optimization approach for designing biomass supply chain
(2012-12)
Scope and Method of Study:
