Root Productivity (BNPP), Total carbon and Nitrogen - Annual Crops (G1-G4)

Biomass and total carbon and total nitrogen measurements from the roots of GLBRC annual crops are presented here. 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 .

This datatable is part of the GLBRC Roots dataset. Below ground primary production for the GLBRC plots.
