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 ...
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 ...
Net ecosystem exchange of carbon dioxide and water vapor fluxes in switchgrass and high biomass sorghum
(2013-12)
Understanding carbon and water dynamics of switchgrass (Panicum virgatum L.) and high biomass sorghum ((Sorghum bicolor L. Moench) ecosystems is crucial as the acreage of these feedstocks is expanding for cellulosic biofuels. ...
Experimental investigation and simulation of a fluidized-bed gasifier using switchgrass
(2013-12)
The overall goal of this research was to improve and optimize yield and composition of syngas generated from biomass gasification using an autothermal lab-scale fluidized-bed gasifier, and to develop a biomass gasification ...
Effects of Torrefaction and Densification on Devolatilization Kinetics and Gasification Performance of Switchgrass
(Oklahoma State University, 2013-12-01)
The overall goal of this research was to investigate effects of pretreatments (torrefaction at 230 and 270°C, densification, and combined torrefaction and densification) on biomass properties, devolatilization kinetics ...
