BOSQUE COUNTY, TEXAS
B21t-15 to 32 inches; reddish brown (5YR 5/4) sandy
clay loam, reddish brown (5YR 4/4) moist; moderate
fine subangular blocky structure; hard, friable; few
fine roots; few fine pores; few patchy clay films on
faces of peds; slightly acid; gradual smooth bound-
ary.
B22t-32 to 70 inches; yellowish red (5YR 5/6) sandy
clay loam, yellowish red (5YR 4/6) moist; weak fine
subangular blocky structure; hard, friable; few fine
roots; few patchy clay films on faces of peds; non-
calcareous; neutral; gradual smooth boundary.
C-70 to 80 inches; reddish yellow (5YR 7/6) sandy clay
loam, reddish yellow (5YR 6/6) moist; massive;
slightly hard, friable; few weakly cemented concre-
tions of calcium carbonate; few small rounded sili-
ceous pebbles; calcareous; moderately alkaline.
Solum thickness ranges from 60 to 80 inches. Sili-
ceous gravel makes up as much as 15 percent of the
volume.
The A horizon is light brownish gray, light brown, gray-
ish brown, dark grayish brown, yellowish brown, brown,
light reddish brown, or reddish brown. The horizon is fine
sandy loam or loamy fine sand. Reaction is medium acid
or slightly acid.
The B2t horizon is reddish brown, red, yellowish red,
reddish yellow, or light reddish brown. This horizon is
sandy clay loam or clay loam. Clay content ranges from
20 to 30 percent. Reaction of the B21t horizon is slightly
acid or neutral. Reaction of the B22t horizon is slightly
acid through moderately alkaline.
The C horizon is light brown, reddish yellow, or light
reddish brown. This horizon is sandy clay loam or loam.
Bolar series
The Bolar series consists of moderately deep, well
drained loamy soils on uplands. These soils formed in
calcareous loamy sediments over interbedded limes-
tones and clayey marl. Slope ranges from 1 to 5 percent.
Typical pedon of Bolar clay loam, 1 to 3 percent
slopes; from intersection of Farm Road 2602 and Farm
Road 217, 1 mile southeast on Farm Road 217 to Mo-
sheim, 0.6 mile southeast on dirt road to dead end, east
0.5 mile, and 100 feet south in cultivated field:
Ap-0 to 5 inches; brown (10YR 4/3) clay loam, dark
brown (10YR 3/3) moist; weak fine granular struc-
ture; hard, friable; common fine roots; few hard lime-
stone fragments; calcareous; moderately alkaline;
abrupt smooth boundary.
A12-5 to 15 inches, very dark grayish brown (10YR
3/2) clay loam, very dark brown (10YR 2/2) moist;
moderate fine subangular blocky structure; hard, fri-
able; common fine roots; few fine weakly cemented
concretions of calcium carbonate; calcareous; mod-
erately alkaline; clear smooth boundary.
B21ca-15 to 27 inches; pale brown (10YR 6/3) clay
loam, brown (10YR 4/3) moist; moderate fine su-bangular blocky structure; hard, firm; few fine roots;
common fine strongly cemented concretions of cal-
cium carbonate; calcareous; moderately alkaline;
gradual smooth boundary.
B22ca-27 to 33 inches; light yellowish brown (10YR
6/4) clay loam, yellowish brown (O10YR 5/4) moist;
moderate fine subangular blocky structure; hard,
firm; few fine roots; many fine strongly cemented
concretions and fragments of calcium carbonate;
calcareous; moderately alkaline; clear smooth
boundary.
B3ca-33 to 37 inches; yellowish brown (10YR 5/6) clay
loam; weak fine subangular blocky structure; inter-
bedded with 35 percent limestone fragments up to 4
inches across; common to many soft masses of
calcium carbonate; calcareous; moderately alkaline;
abrupt smooth boundary.
R-37 to 40 inches; indurated limestone bedrock.
The solum is 20 to 40 inches thick. Fragments of
limestone and calcium carbonate concretions, ranging in
size from gravel to stone, make up from a few to 20
percent, by volume, of the solum. The fragments are
scattered throughout the pedon or as discontinuous
broken remnant stone lines. Calcium carbonate equiva-
lent of the 10- to 40-inch control section is 40 to 75
percent.
The A horizon is dark grayish brown, very dark grayish
brown, brown, dark brown, or very dark brown. This
horizon is clay loam or silty clay loam.
The B horizon is very pale brown, pale brown, light
brown, brown, light yellowish brown, or yellowish brown.
Texture is clay loam or silty clay loam. Some pedons do
not have a B3ca horizon.
The R layer is indurated limestone that is fractured
and interbedded with clayey marl or calcareous shale.
Bosque series
The Bosque series consists of deep, well drained
loamy soils on flood plains. These soils formed in thick
beds of alluvial sediments. Slope ranges from 0 to 1
percent.
Typical pedon of Bosque loam, occasionally flooded;
from the intersection of Texas Highway 144 and Texas
Highway 22 in Meridian, 0.25 mile west on Texas High-
way 22, and 400 feet south in pasture:
A11-0 to 10 inches; brown (10OYR 4/3) loam, dark
brown (10YR 3/3) moist; weak fine subangular
blocky and granular structure; slightly hard, friable;
common fine roots; few fine concretions of calcium
carbonate; few round water worn pebbles; calcare-
ous; moderately alkaline; clear smooth boundary.
A12-10 to 26 inches; dark grayish brown (10YR 4/2)
loam, very dark grayish brown (10YR 3/2) moist;
weak fine subangular blocky structure; slightly hard,
friable; few fine roots; common films and threads of43
