Stable isotope and hyphal biomass data from Jach-Smith and Jackson (2020) — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Stable isotope and AMF hyphal biomass responses to zero, medium and high nitrogen application rates.

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.
