Root biomass — GLBRC Biofuel Cropping System Experiment
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Root biomass sampled with deep coring and pit excavations. Samples were taken on top of, and between plants and as part of the soil excavation. The deep core samples were taken within the perimeter of the pit. In this data table the biomass from the core samples has already been added to the pit biomass. Root biomass of deep cores is not scaled to plant density and should not be used as a direct measure of standing root biomass.
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.
