Soil Bulk Density by Depth - Deep Cores

Soil bulk density of deep core soil samples collected from the LTER Main Site and Successional and Forest sites, organized by treatment, replicate and depth. Bulk densities are calculated by obtaining the volume from the diameter of the core and the length of the horizon.

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.
