- Drainage class: Well drained
- Permeability: Moderate
- Parent material: Loamy marine sediments
- Landscape: Coastal Plain

Commonly Associated Soils
Benevolence, Faceville, Greenville, Norfolk, and Orangeburg soils are
commonly associated with the Red Bay series.
- The Benevolence soils are in positions similar to those of the Red Bay
soils or slightly lower, have hues that are more yellow, and have a
coarse-loamy control section.
- The Faceville soils are in positions similar to those of the Red Bay
soils, have hues that are more yellow, and have a fine control section.
- The Greenville soils are in positions similar to those of the Red Bay
soils or slightly higher and have a fine control section.
- The Norfolk soils are in the slightly lower positions and have hues that
are more yellow.
- The Orangeburg soils are in positions similar to those of the Red Bay
soils or slightly lower and have hues that are more yellow.
Typical Pedon
Red Bay loamy sand, 2 to 5 percent slopes; about 0.3 mile east of the
intersection of Benevolence Road and County Road 105 and 200 feet south of the
county road; Randolph County, Georgia; USGS Benevolence topographic quadrangle;
lat. 31 degrees 51 minutes 4 seconds N. and long. 84 degrees 44 minutes 49
seconds W., NAD27.
- Ap—0 to 8 inches; dark reddish brown (2.5YR 3/3) loamy sand; weak fine
granular structure; very friable; common fine roots; slightly acid; clear
smooth boundary.
- Bt1—8 to 40 inches; dark red (2.5YR 3/6) sandy loam; weak medium
subangular blocky structure; friable; few fine roots; sand grains coated and
bridged with clay; moderately acid; gradual smooth boundary.
- Bt2—40 to 80 inches; dark red (10R 3/6) sandy clay loam; moderate medium
subangular blocky structure; friable; common faint clay films on faces of peds;
strongly acid.

- Reaction: Very strongly acid to moderately acid in the upper part
of the solum and very strongly acid or strongly acid in the lower part, except
where the surface layer has been limed
