Vanella soil landscape

Soil profile: A soil profile of Vanella cobbly fine sandy loam. The lower part of the argillic horizon starting at approximately 80 centimeters is red, cobbly clay loam. These soils formed in old colluvium derived from sandstone, shale, siltstone, limestone, dolomitic limestone, quartzite, metasandstone, and phyllite. (Soil Survey of Rockbridge County, Virginia; by Mary Ellen Cook, Natural Resources Conservation Service)

 

Landscape: A view looking north at Big House and Little House Mountains. The cleared areas are dominantly Carbo, Opequon, Groseclose, Tumbling, and Vanella soils.

 

Landscape: Hills and mountains

Landform: Debris flows, hillslopes and mountain slopes

MLRA(s): 130A, 147

Hillslope Profile Position: Summits, backslopes and footslopes

Geomorphic Component: Interfluve, crest, nose slope, side slope, base slope and mountainflank

Parent Material: Old colluvium derived from sandstone, shale, limestone, quartzite, metasandstone and phyllite.

Slope: 3 to 35 percent.

Elevation: 1,000 to 3,000 feet

Frost-free period: 130 to 205 days

Mean Annual Air Temperature: 53 to 56 degrees F

Mean Annual Precipitation: 38 to 42 inches

 

TAXONOMIC CLASS: Fine-loamy, siliceous, subactive, mesic Typic Paleudults

 

Thickness of the Ochric epipedon: 0 to 60 cm (0 to 24 inches) (A, E and BE horizons)

Depth of the Argillic horizon: 60 to 165 cm (24 to 65 inches) (Bt horizons). The weighted average of clay is 18 to 35 percent in the particle-size control section.

Solum thickness: Greater than 150 cm (60 inches)

Depth to bedrock: Greater than 150 cm (60 inches)

Depth Class: Very Deep

Rock fragment content: 0 to 35 percent in the upper horizons and particle-size control section. Rock fragments can range from 0 to 60 percent below the control section. They consist of a mixture of subrounded and subangular fragments of sandstone, shale, quartzite, metasandstone and phyllite.

Soil Reaction: Very strongly acid or strongly acid except where limed.

 

USE AND VEGETATION:

Major Uses: Most areas are in forest. Some areas are used for pasture and cultivated crops.

Dominant Vegetation: Chestnut oak, scarlet oak, post oak, Virginia pine, eastern white pine, and pitch pine.

 

DISTRIBUTION AND EXTENT:

Distribution: The Northern Appalachian Ridges and Valleys (MLRA 147) and the metasedimentary areas along the western flank of the Northern Blue Ridge (MLRA 130A).

Extent: Moderate
