Plant Carbon and Nitrogen- GLBRC Switchgrass Nitrogen/Harvest Exp.

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Percent carbon and nitrogen in switchgrass plants in the Switchgrass Nitrogen/Harvest Experiment at the KBS GLBRC Biofuel Intensive site. Plants are grown under 8 treatments of nitrogen fertilizer. From 2010 through 2012 there were also two harvest strategies for each nitrogen treatment.

This datatable is part of the GLBRC Plant Chemical Analyses dataset.
