Switchgrass as an Energy Crop: Fertilization, Cultivar, and Cutting Management
Switchgrass (Panicum virgatum L.) has potential as a biofuels feedstock. Major management questions include cultivar selection, cutting management, and optimizing N fertilization. Four cultivars of switchgrass were evaluated under two cutting regimes at eight locations within KY, NC, TN, VA, and WV …

Perennial energy crops on riparian buffers affect nitrogen cycling microbial communities
Production of perennial bioenergy crops on farmland that is suboptimal for food crops has been suggested for ecosystem services such as mitigating greenhouse gas emissions and reducing nutrient loss while producing sustainable bioenergy feedstocks. Even though we understand the relationship between …

Switchable butadiene sulfone pretreatment of lignocellulosic biomass
… Miscanthus x giganteus, a perennial grass and energy crop, was pretreated with butadiene sulfone in a batch reactor at 90 °C-110 °C for 6-30 h. The ability of butadiene sulfone to “switch” in equilibrium to 1,3-butadiene and sulfur dioxide, allowed for the formation of sulfurous acid in the …
