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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Total carbon and nitrogen determinations of deep core soil samples from the LTER Main Site and Successional and Forested sites organized by treatment, replicate and core depth (surface, middle, deep) sections.

This datatable is part of the Soil Carbon and Nitrogen Deep Core Surveys dataset. An LTER project goal is to periodically collect and analyze deep soil cores for the main site treatments and successional and forest sites. Soil is sampled to a depth of one meter, and analyzed for horizon depths, texture, moisture, and carbon and nitrogen content.
