Carbon and Nitrogen from Fine Roots sampled from In-growth Chambers — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Carbon and nitrogen measurements were made on the fine roots that were grown in field root growth chambers mid-season and at the end of the season.

Stations were grouped before analyzing for carbon and nitrogen.

This datatable is part of the GLBRC Roots dataset.

Below ground primary production for the GLBRC plots.
