MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia

SERIES ESTABLISHED: Washington County, Virginia, 1940.

REMARKS: Diagnostic horizons recognized in this pedon are:

Ochric epedon - The zone between 0 to 7 inches (Ap hroizon)
Argillic horizon - The zone from 7 to 60 inches (Bt horizons.
Series Control Section - 0 to 152 cm (0 to 60 inches)

12/2004 Based on three sampled pedons at the NSSL, the CE activity class is subactive. Changed clayey to fine textural family. MAV

5/2010 Updated Competing Series and Geographically Associated Soils sections. Expanded range in characteristics of AB horizon.

ADDITIONAL DATA: S70VA165-4 is from the type location. Additional data is available for Lodi soils in Clarke, Montgomery, and Pulaski Counties, Virginia.
