BOSQUE COUNTY, TEXAS
This Duffau soil is in capability subclass lie and in
Sandy Loam range site.
20-Duffau fine sandy loam, 3 to 5 percent slopes.
This deep, gently sloping soil is on plane to convex
uplands. Areas are irregular in shape and range from 5
to 50 acres.
Typically, the surface layer is fine sandy loam about 10
inches thick that is dark grayish brown in the upper part
and pale brown in the lower part. From 10 to about 60
inches is yellowish red sandy clay loam that is reddish
yellow in the lower part. This soil is slightly acid through-
out.
This soil is well drained. Permeability is moderate, and
available water capacity is high. Crops on this soil re-
spond well to fertilizer. The range in moisture content at
which this soil can be best worked is narrow. The root
zone is deep, but some plant roots are restricted by the
clayey lower layers. The water erosion hazard is moder-
ate. The soil blowing hazard is moderate.
Included in mapped areas of this soil are small areas
of Selden and Windthorst soils. They make up less than
20 percent of this map unit.
This Duffau soil is used mainly as rangeland. Potential
for native range plants is high. The climax plant commu-
nity is a mixture of mid and short grasses and forbs.
Management includes controlled grazing, proper stock-
ing, and brush control.
Potential for cultivated crops is medium. Grain sor-
ghum is suited to this soil. Terraces and contour cultiva-
tion help control erosion. Plant residues left on the soil
surface help conserve moisture, regulate soil tempera-
ture, and maintain productivity and tilth. Potential for pas-
ture plants is high. Kleingrass, bermudagrass, and King
Ranch bluestem are the commonly grown grasses on
this soil.
Potential for most urban uses is medium. Shrink-swell
is the main limitation. Low strength is the main limitation
for local roads and streets.
This Duffau soil is in capability subclass ille and in
Sandy Loam range site.
21-Duffau fine sandy loam, 1 to 5 percent slopes,
eroded. This deep, gently sloping soil is on convex up-
lands. Areas are irregular in shape and range from 5 to
50 acres. Sheet erosion has removed on the average
about 75 percent of the original surface layer. An occa-
sional shallow gulley, about 12 inches deep, occurs in
places, but these are crossable with farm machinery.
Some areas have a sandy clay loam surface layer be-
cause parts of the sandy clay loam subsoil have been
incorporated with the surface layer by tillage.
Typically, the surface layer is dark grayish brown,
slightly acid fine sandy loam about 3 inches thick. From
3 to about 60 inches is slightly acid, yellowish red sandy
clay loam that is reddish yellow in the lower part.
This soil is well drained. Permeability is moderate, and
available water capacity is high. Crops on this soil re-spond well to fertilizer. The root zone is deep. The water
erosion hazard is moderate. The soil blowing hazard is
moderate.
Included in mapped areas of this soil are small areas
of Selden and Windthorst soils. They make up less than
20 percent of this map unit.
This Duffau soil is used mainly as cropland. Potential
for cultivated crops is medium. Grain sorghum, truck
crops, and peanuts do well on this soil. Terraces, con-
tour cultivation, and plant residues left on the soil sur-
face help control erosion, conserve moisture, and main-
tain productivity. Potential for pasture plants is high.
Kleingrass, bermudagrass, and King Ranch bluestem are
the commonly grown grasses on this soil.
Potential for native range plants is high. The climax
plant community is a mixture of mid and short grasses.
Management includes controlled grazing, proper stock-
ing, and brush control.
Potential for most urban uses is medium. Shrink-swell
is the main limitation that can be overcome by proper
design. Low strength is the main limitation for local roads
and streets.
This Duffau soil is in capability subclass ille and in
Sandy Loam range site.
22-Eckrant association, gently undulating. This
shallow and very shallow soil is on uplands. Slopes
range from 1 to 5 percent. These areas are irregular in
shape and range from 15 to several hundred acres.
About 85 percent of this map unit is Eckrant and
closely similar soils, and 15 percent is other soils and
limestone outcrop. These closely similar soils could be
separated, but because use and management are similar
it is not justified.
Typically, the surface layer of Eckrant soils is very dark
gray, cobbly clay about 10 inches thick. About one-half
of this layer is cobbles and fragments of limestone over
3 inches in diameter. Underlying material is fractured,
indurated limestone bedrock. Soils closely similar to Eck-
rant include a soil that is calcareous to the surface, a
soil that has 10 to 35 percent gravel, and a soil that is
20 to 30 inches to bedrock.
The Eckrant soil is well drained. Permeability is moder-
ately slow, and available water capacity is very low. The
root zone is restricted because of shallow and very shal-
low depths to rock. The water erosion hazard is severe.
The soil blowing hazard is slight.
Other soils in this map unit are small areas of Bolar,
Cranfill, and Tarrant. The limestone outcrops are mainly
on crests of ridges. These soils and limestone outcrops
make up about 15 percent of the association.
This map unit is used as rangeland. Potential for
native range plants is low. The climax plant community is
an open tall and mid grass prairie with live oak scattered
throughout (fig. 4). Management includes controlled graz-
ing, proper stocking, and brush control.
This unit is not suited to cultivated crops. Potential for
pasture and urban uses is low. Stones and depth to rock
are limitations that are diffucult to overcome.15
