Soil Total Carbon and Nitrogen by Depth - Deep Cores

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.
