\<@27\>Associated Soils

\<@32\>The Blanton soils are commonly associated on the landscape with
Alaga, Albany, Alpin, Bibb, Bigbee, Bonneau, Boulogne, Chipley,
Falmouth, Ichetucknee, Lynchburg, Ocilla, Ousley, Padlock, Pantego,
Pedro Variant, Troup, and Wampee soils.

    excessively drained.

    drained.

    drained.

    drained.

    with a combined thickness of 20 to 40 inches and are well drained.

    drained.

    and subsurface layers with a combined thickness of less than 20
    inches, and are somewhat poorly drained.

    layers with a combined thickness of less than 20 inches, are deep to
    limestone bedrock, and are somewhat poorly drained.

    horizons with a combined thickness of less than 20 inches and are
    somewhat poorly drained.

    layers with a combined thickness of 20 to 40 inches and are somewhat
    poorly drained.

-   \<@29\>The Padlock soils have sandy surface and subsurface layers
    with a combined thickness of less than 20 inches and have a clayey
    subsoil.

    with a combined thickness of less than 20 inches and are very poorly
    drained.

-   \<@29\>The Pedro Variant soils are shallow to limestone bedrock and
    are well drained.

-   \<@29\>The Troup soils have a subsoil that is redder than that of
    the Blanton soils and are somewhat excessively drained.

\<@27\>Typical Pedon

\<@32\>Blanton fine sand, in an area of Blanton-Padlock-Alpin complex, 0
to 5 percent slopes; about 1.0 mile south of Florida Highway 252, about
800 feet west of Birley Road, and 25 feet east of Woods Road; sec. 8, T.
4 S., R. 16 E.; O'Brien, Florida, USGS 7.5-minute quadrangle; lat. 30
degrees, 6 minutes, 7 seconds north and long. 82 degrees, 57 minutes, 1
second west.

\<@23\>Ap---0 to 5 inches; dark gray (10YR 4/1) fine sand; weak fine
granular structure; common very fine and medium roots; strongly acid;
clear wavy boundary.

\<@33\>E1---5 to 13 inches; light olive brown (2.5Y 5/3) fine sand;
single grain; loose; common fine roots; strongly acid; gradual smooth
boundary.

\<@33\>E2---13 to 27 inches; light yellowish brown (2.5Y 6/3) fine sand;
single grain; loose; common fine and medium roots; strongly acid; clear
wavy boundary.

\<@33\>E3---27 to 36 inches; pale yellow (2.5Y 8/3) fine sand; single
grain; loose; common medium roots; strongly acid; gradual wavy boundary.

\<@33\>E4---36 to 41 inches; light gray (2.5Y 7/2) fine sand; single
grain; loose; strongly acid; clear wavy boundary.

medium subangular blocky structure; very friable, slightly sticky and
slightly plastic; common medium distinct light brownish gray (2.5Y 6/2)
areas of iron depletion; strongly acid; gradual wavy boundary.

\<@33\>Bt2---48 to 67 inches; 30 percent yellowish red (5YR 5/6), 30
percent yellowish brown (10YR 5/6), and 40 percent light brownish gray
(2.5Y 6/2) sandy clay loam; weak medium subangular blocky structure;
friable, moderately sticky and slightly plastic; the areas of yellowish
red and yellowish brown are iron accumulations; the areas of light
brownish gray are iron depletions; strongly acid; gradual wavy boundary.

\<@33\>Btg1---67 to 74 inches; gray (10YR 6/1) sandy clay loam; moderate
medium subangular blocky structure; friable, moderately sticky and
slightly plastic; common medium distinct yellowish brown (10YR 5/6) and
many coarse prominent light olive brown (2.5Y 5/6) masses of iron
accumulation; strongly acid; gradual wavy boundary.

\<@33\>Btg2---74 to 80 inches; gray (10YR 6/1) sandy clay loam; moderate
medium subangular blocky structure; friable, moderately sticky and

\<@27\>Range in Characteristics

\<@32\>The thickness of the solum ranges from 60 to more than 80 inches.
Reaction ranges from very strongly acid to moderately acid throughout,
except where lime has been applied. The content of plinthite is less
than 5 percent within a depth of 60 inches but ranges up to 15 percent
below a depth of 60 inches.

\<@32\>The A or Ap horizon has hue of 10YR or 2.5Y, value of 3 to 7, and
chroma of 1 to 4. The horizon is less than 10 inches thick where value
is 3.5 or less. The texture is sand, fine sand, coarse sand, loamy sand,
loamy fine sand, or the gravelly analogs of those textures.

\<@32\>The E horizon has hue of 7.5YR to 2.5Y, value of 5 to 8, and
chroma of 1 to 8. The texture has the same range as the A or Ap horizon.
The E horizon has 50 percent or more uncoated sand grains.

\<@32\>The BE horizon, where present, has hue of 10YR or 2.5Y, value of
5 to 7, and chroma of 3 to 8. The texture is loamy sand, loamy coarse
sand, loamy fine sand, or sandy loam.

\<@32\>The Bt horizon has hue of 7.5YR to 2.5Y, value of 5 to 7, and
chroma of 3 to 8; or it has no dominant color and is multicolored in
shades of brown, yellow, red, and gray. In most pedons, the upper 10
inches of the horizon has redoximorphic depletions. The Bt horizon is
loamy sand, loamy coarse sand, loamy fine sand, sandy loam, fine sandy
loam, or sandy clay loam.

\<@32\>The Btg horizon, where present, has hue of 7.5YR to 5Y, value of
5 to 8, and chroma of 1 or 2. It has common or many redoximorphic
features in shades of brown, yellow, red, and gray. The texture is sandy
loam, fine sandy loam, or sandy clay loam, and, below a depth of 60
inches, ranges to sandy clay.
