Plant Total Carbon and Nitrogen — Switchgrass Nitrogen Rate Experiment
Total carbon and nitrogen content in the switchgrass crop of the Switchgrass Nitrogen Rate Experiment. A subsample of the machine harvested crop is dried, ground, and analyzed for carbon and nitrogen content, reported as a percentage; the remaining subsample is archived.
This datatable is part of the Switchgrass Nitrogen Rate Experiment dataset.
This dataset contains data from the Switchgrass Nitrogen Rate Experiment (formerly Nitrogen/Harvest) at the KBS GLBRC Intensive Field Site. Switchgrass is grown under 8 rates of nitrogen fertilization (F1-F8; 0-196 kg N/ha) with each treatment plot replicated in four blocks (R1-R4). From 2010–2012, the experiment also included split plots with two harvest strategies (H1, H2; 1 vs 2 harvests/yr) for each nitrogen treatment; from 2013 onward all split plots are harvested only once in the fall, with yields measured separately 2013-2022 and combined starting in 2023.
