Tanasee soil series
A representative soil profile of the Tanasee soil series in North Carolina.
The Tanasee series consists of very deep, well drained soils on toe slopes, fans and benches in coves at high elevations in the Southern Blue Ridge mountains, MLRA 130B. They formed in colluvium derived from materials weathered from felsic to mafic igneous and high-grade metamorphic rocks. Near the type location, mean annual air temperature is about 45 degrees F., and mean annual precipitation is about 72 inches. Slope ranges from 2 to 95 percent. (Soil Survey of Buncombe County, North Carolina; by Mark S. Hudson, Natural Resources Conservation Service)
TAXONOMIC CLASS: Fine-loamy, isotic, frigid Typic Humudepts
Depth to bedrock is more than 60 inchesContent of offlakes of mica is few or common throughout. Rock fragment content is less than 35 percent in the upper 40 inches and less than 60 percent below 40 inches. In the 10 to 40 inch control section, loamy horizons that overlie sandy horizons have more than 50 percent fine and coarser sand.
DISTRIBUTION AND EXTENT: High elevations in the Southern Blue Ridge mountains, MLRA 130B of North Carolina and Virginia, and possibly Tennessee. This series is of moderate extent.
The Tanasee series was formerly included with the Tusquitee series. However, Tusquitee soils are in a mesic family.
The 1/97 revision placed Tanasee soils in a fine-loamy particle-size class. This series was formerly placed in a coarse-loamy particle-size class. Laboratory PSA (pipette method) and corresponding field texture estimates (feel method) indicate control section clay contents of generally 12 to 24 percent, with most pedons marginally coarse-loamy. Fine-loamy particle-size class placement is based on the presence of amorphous (non-crystalline) clay-size material associated with the relatively high organic matter content found in these soils. Although field estimates, laboratory measurements, and calculated values may vary, clay content in the particle-size control section is generally less than 25 percent. Although Tanasee soils may exhibit some of the characteristics of andic soil properties, they lack the volcanic glass found in soils of similar taxa in the Western United States.
