Poplar Understory Biomass — GLBRC Biofuel Cropping System Experiment
Data in the KBS GLBRC core database may not be published without written permission of the lead investigator or project director Full terms of use
Biomass of the understory plant growth in the BCSE poplar treatment (G8); including at peak biomass as well as sampling before agronomic activities such as mowing, herbicide application, and cover crop harvest. Peak biomass samples were sorted to species through 2018, but from 2019 onward are left “unsorted”, as are samples from the other sampling campaigns.
This datatable is part of the GLBRC Aboveground Plant Biomass dataset.
This dataset contains aboveground biomass data for all treatments (G1-G10) of the GLBRC Biofuel Cropping System Experiment (BCSE). Biomass samples are taken at peak biomass for estimation of aboveground net primary production (ANPP) as well as other sampling campaigns such as cover crop harvest or to capture biomass before agronomic activities. Also included are annual stem diameter measurements and occasional destructive harvests for poplar (G8). See the ANPP protocol for description of the sampling and measurement methods used for each of the treatments. Typically, biomass is sampled around each sampling station (S1-S3) in each replicate plot (R1-R5). Belowground plant biomass is available in a different dataset.
