Poster Title: Evaluating Cropping Systems for Feed, Heat, and Biofuel Production
Authors: Gustavo Camargo and Tom Richard, Penn State University
Poster Abstract: Introducing energy double crops like winter rye and spring canola into conventional NE cropping systems can increase productivity per acre and provide environmental benefits. However, this more intensive production also requires additional inputs. This study examines the inputs and outputs of both energy and greenhouse gases for three different cropping systems introduced in a typical crop farm Centre County, PA, based on a conventional corn/soybeans/alfalfa rotation. Results indicate that the rye double crop system has the greatest increase in net energy output and reduction in greenhouse gas emissions, while the canola has intermediate benefits in both fuel and greenhouse gas impacts.
