Root Productivity (BNPP) - 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Below ground productivity for the perennial systems was determined by examining roots collected with a deep core sample. The roots were washed and weighted
This datatable is part of the GLBRC Roots dataset.
Below ground primary production for the GLBRC plots.
