In 2017 at the GLBRC BCSE plots, above- and belowground plant biomass were sampled at maturity near- and post-machine harvest time, respectively. All samples were collected from all treatments (G1-G10), Blocks 2 through 4. The overarching goal of this project is to determine any differences on above- and belowground biomass production between annual and perennial crops dedicated to bioenergy production after ten years of establishment. original data source http://lter.kbs.msu.edu/datasets/183
