CenUSA Bioenergy is a coordinated research and education effort investigating the creation of a regional system in the Central US for producing advanced transportation fuels from perennial grasses on land that is either unsuitable or marginal for row crop production. In addition to producing advanced biofuels, the proposed system will improve the sustainability of existing cropping systems by reducing agricultural runoff of nutrients in soil and increasing carbon sequestration.
CenUSA Bioenergy researchers from Iowa State University, Purdue University, University of Wisconsin, University of Minnesota, University of Nebraska, University of Illinois and the USDA Agricultural Research Service cover topics of interest to producers and growers in the following resources.
