Aboveground Biomass of Annual Crops — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Aboveground biomass of BCSE annual crop treatments (G1-G4, depending on year). Peak biomass samples are separated to species; cover crop harvests are separated to cover crop species and an “unsorted” aggregate sample of any additional species. Surface litter samples are also included in the dataset but likely represent previous years’ growth and should not be included in ANPP estimates.
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.
