GLBRC Sustainability Data Catalog

Above ground Plant Carbon and Nitrogen from the root excavation projecdt

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

This datatable is part of the Whole plant carbon and nitrogen dataset. 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.
