Agronomic Yields - Switchgrass — GLBRC Switchgrass Nitrogen Rate 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Agronomic yields for the Switchgrass Nitrogen/Harvest Experiment on the GLBRC Biofuel Intensive Site. Plants are grown under 8 treatments of nitrogen fertilizer and two harvest strategies. Note that in 2009 there was only one harvest.
This datatable is part of the KBS GLBRC Agronomic Yields dataset.
Agronomic yield record for the KBS Great Lakes Biofuels Research Center (GLBRC) Intensive site and the GLBRC scale-up fields.
