Poplar Leaf Litter 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Biomass of leaf litter collected from litter traps in the BCSE poplar treatment (G8). Two litter traps are deployed per replicate plot in mid to late summer and litter samples are collected roughly every two weeks. Note that litter traps are identified by number (at Arlington) or by orientation in the plot (KBS).
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.
