Bulk Density from the deep core sample campaign
Bulk density values for the deep core sampling campaign. These are calculated by obtaining the volume from the diameter of the core and the length of the horizon.
The
standard data use policy applies to the this dataset
Context:
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.
