Root biomass (BNPP) and Total carbon and Nitrogen - Annual Crops (G1-G4)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 and total carbon and total nitrogen measurements from the roots of GLBRC annual crops are presented here. Arlington roots are collected from one square meter and KBS roots are collected from one plant. KBS root biomass data is averaged in this data table by station in order to combine the biomass with the carbon and nitrogen data since carbon and nitrogen data is grouped by station. The root biomass by station can be found at this data table link . Arlington root data is given by station in this table and the biomass is repeated at the link given above.
This datatable is part of the GLBRC Roots dataset. Below ground primary production for the GLBRC plots.
