Toxey Series

\<@32\>The Toxey series consists of very deep, moderately well drained
soils that formed in marine sediments consisting of thin strata of acid
clay underlain by stratified alkaline, loamy and clayey sediments and
chalk or marl. These soils are in the uplands in the southwestern part
of the county. They are on narrow ridgetops and on benches. Slopes range
from 3 to 8 percent. These soils are fine, smectitic, thermic Vertic
Eutrudepts.

\<@32\>Toxey soils are geographically associated with Brantley, Hannon,
and Okeelala soils. Brantley soils are in the slightly higher positions
on ridgetops or in the lower positions on side slopes. They have a
clayey argillic horizon and are acid throughout. Hannon soils are in
positions similar to those of the Toxey soils and have hue of 7.5YR or
redder in the upper part of the solum. Okeelala soils are in lower
positions than those of the Toxey soils and are fine-loamy.

\<@33\>BC---15 to 24 inches; pale olive (5Y 6/3) and light yellowish
brown (2.5Y 6/3) silty clay; strong conchoidal rock structure; firm; few
fine and very fine roots; common fine soft black masses and stains (iron
and manganese oxides); common soft masses of calcium carbonate; many
coarse distinct dark yellowish brown (10YR 4/4) and few fine and medium
distinct yellowish brown (10YR 5/6) masses of iron accumulation on
fracture planes; slightly acid; clear irregular boundary.

\<@33\>2C1---24 to 44 inches; pale yellow (5Y 7/3) silty clay; weak
thick platy rock structure parting to strong coarse and medium angular
blocky; vertical and horizontal fracture planes are 1 to 2 inches apart;
very firm; few thin strata of brownish yellow (10YR 6/6) silty clay;
common fine soft black masses and stains (iron and manganese oxides);
common fine white fragments of shell; common soft masses of calcium
carbonate; common medium distinct dark yellowish brown (10YR 4/6),
strong brown (7.5YR 4/6), and dark brown (7.5YR 3/4) masses of iron
accumulation on fracture planes; strongly effervescent; slightly
alkaline; clear irregular boundary.

\<@33\>2C2---44 to 53 inches; brownish yellow (10YR 6/6) silty clay
loam; massive; many dark sand grains; few fine and medium nodules of
calcium carbonate; few fine soft masses of calcium carbonate; violently
effervescent; slightly alkaline; clear irregular boundary.

\<@33\>2C3---53 to 63 inches; pale olive (5Y 6/3) clay loam; massive;
many dark sand grains; common fine nodules of calcium carbonate;
violently effervescent; slightly alkaline; clear wavy boundary.

\<@33\>2C4---63 to 80 inches; strong brown (7.5YR 4/6) clay loam;
massive; many dark sand grains; few fine nodules of calcium carbonate;
strongly effervescent; slightly alkaline.

\<@8\>The depth to an alkaline horizon ranges from 10 to 35 inches. The
thickness of the solum ranges from 10 to 50 inches.

\<@32\>The A or Ap horizon has hue of 10YR or 2.5Y, value of 3 or 4, and
chroma of 1 to 3. It is very strongly acid or strongly acid.

\<@32\>The upper part of the Bw horizon has hue of 7.5YR to 2.5Y, value
of 4 to 6, and chroma of 3 to 6. The quantity of redoximorphic
depletions in shades of gray and redoximorphic accumulations in shades
of brown, yellow, and red ranges from none to common. The lower part has
hue of 10YR to 5Y, value of 5 to 7, and chroma of 3 to 6. It has few to
many redoximorphic depletions in shades of gray and redoximorphic
accumulations in shades of brown, yellow, and red. The texture of the Bw
horizon is silty clay or clay. Reaction ranges from very strongly acid
to moderately acid.

\<@32\>The BC horizon, which occurs in most pedons, has the same range
in color as the lower part of the Bw horizon. It is silty clay loam,
clay loam, silty clay, or clay. Reaction ranges from slightly acid to
moderately alkaline. The quantity of soft masses and nodules of calcium
carbonate ranges from none to common.

\<@32\>The 2C horizon is commonly stratified. It commonly has hue of
10YR to 5Y or less commonly 7.5YR, value of 4 to 7, and chroma of 3 to
6; or it has no dominant matrix color and is multicolored in shades of
olive, brown, and gray. It is massive or has platy or blocky rock
structure. It is sandy clay loam, silty clay loam, clay loam, silty
clay, or clay. It commonly contains few to many angular, soft shale-like
fragments. It is slightly alkaline or moderately alkaline. It has few to
many soft masses or nodules or both of calcium carbonate. The quantity
of soft black masses or stains of iron and manganese oxides ranges from
none to common. Some pedons have strata of chalk or marl below a depth
of 60 inches.
