Above Ground Biomass of Herbaceous Perennial crops; treatments 5,6,7,9,10 — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 the five herbaceous biofuel crop treatments on the GLBRC Intensive Site: switchgrass, miscanthus, grass mix, old field and prairie. Additional campaigns (samplings with different timing or purpose) are also included in this datatable.

This datatable is part of the GLBRC Annual Net Primary Productivity dataset. This dataset contains the aboveground biomass data. Annual net primary production (ANPP) data is measured at peak biomass for a given treatment. Additional ANPP measurements are made where appropriate such as occasional destructive harvests for poplar. See the ANPP protocols for descriptions of the sampling and measurement methods for each of the treatments. Below ground net primary production (BNPP) are available for these same sites.
