Soil Total Carbon and Nitrogen by Depth - Deep Cores

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Carbon and nitrogen measurements of deep core soil samples from the GLBRC Biofuel Scale-up sites.

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.
