Below Ground Productivity of Perennial Crops (G5-G10) — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Standing stock of live and dead root biomass sampled at the end of the growing season from four depth ranges down to one meter.

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