Poplar - Understory Biomass

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Understory biomass sampled on the poplar treatments (G8) in the Biofuel Cropping System Experiment (BCSE) including cover crop and weed biomass. Cover crops were only sampled in 2008 and 2009. KBS poplar weed biomass was sampled in 2008-2009 and 2012-2013; sampling was discontinued in 2014.

This datatable is part of the KBS GLBRC Annual Net Primary Productivity dataset. This dataset contains the aboveground annual net primary production (ANPP) data on the KBS Great Lakes Bioenergy Research Center (GLBRC) intensive sites and GLBRC scale-up fields. This dataset contains the aboveground annual net primary production (ANPP) data. ANPP 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.
