MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: City of Virginia Beach, Virginia, 1979. The name is from a small community.
REMARKS: Acredale soils have been included with Bladen and Roanoke soils in past mapping.
ADDITIONAL DATA: Virginia Polytechnic Institute and State University soil survey lab data shows the typical pedon of the Acredale series to have a base saturation of 74.67 percent at 50 inches below the top of the argillic. The particle-size control section has 26 percent clay, 55 percent silt, and 9 percent sand that is coarser than very fine sand as a weighted average, with 76 percent quartz and 20 percent weatherable minerals, mainly feldspar and mica, in the 20 to 2,000 micron fraction.
