Biomass of the KBS GLBRC Scaleup 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Annual biomass of the KBS GLBRC scale-up fields at Marshall Farms and Lux Arbor Reserve. Biomass of non-crop (weeds) species are also included. Treatments were first applied in 2010; all fields were planted with soy in 2009. These data are collected with quadrats. For total yield data see http://data.sustainability.glbrc.org/datatables/267 .
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.
