Total Soil Carbon and Nitrogen - GLBRC Intensive Sites
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Total soil carbon and nitrogen measurements at several depths from deep core samples and other soil cores samples.
This datatable is part of the GLBRC Deep Core Soil Surveys dataset. The GLBRC periodically (presently every 5 years) collects and analyzes deep soil cores for the GLBR Intensive Sites and the GLBRC Scale-up sites. Soil is sampled to a depth of one meter, and analyzed at various depths for bulk density, texture, moisture, and carbon and nitrogen content. Soil horizons are also identified.
