Fine 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Fine root production estimated using root in-growth cores. To determine an approximate peak standing crop, two root in-growth cores were installed at the beginning of the growing season at each sampling location; one of them was collected mid-season and the other was collected at the end of the season. BNPP (fine root biomass to given depth) was measured.
This datatable is part of the GLBRC Roots dataset.
Below ground primary production for the GLBRC plots.
