SOIL SURVEY REGIONAL OFFICE (SSRO) RESPONSIBLE: Raleigh, North Carolina
DISTRIBUTION AND EXTENT:
Distribution: Virginia and North Carolina
Extent: Moderate
SERIES ESTABLISHED: Halifax County, Virginia, 2003.
REMARKS: Nathalie soils were previously mapped as Appling soils. The creation of a mesic region within the southern Piedmont necessitated the establishment of a counterpart to the Appling series. Lab data supports the mineralogy classification of kaolinitic in this portion of MLRA 136, however identification of a kandic horizon is marginal and varied. Some of these soils have been mapped with the Buckhall series. Buckhall soils are not kandic and have mixed mineralogy with moderate shrink-swell potential.
Diagnostic horizons and soil characteristics recognized in this pedon:
Ochric epipedon--the zone from 0 to 9 inches (Ap horizon)
Argillic horizon--the zone from 9 to 52 inches (BA, Bt, and BC horizons)
Kandic horizon--the zone from 9 to 52 inches (BA, Bt, and BC horizons)
Other soil features identified with this pedon:
Series control section--the zone from 0 to 60 inches
ADDITIONAL DATA:
Laboratory Data: Reference data for particle-size and chemistry of the Bt horizon is available from Virginia Tech., Blacksburg, VA.
