7. Miguel
Gently sloping, very deep, slightly acid, well drained,
loamy soils on uplands
This map unit consists of gently sloping uplands
that are dissected by small and medium drainageways.
The slowly permeable Miguel soils are on side slopes
and hilltops.
This map unit makes up about 4 percent of the
county (fig. 7). It is about 58 percent Miguel soils and
42 percent soils of minor extent.
Typically, the surface layer of the Miguel soils is
yellowish brown, fine sandy loam about 8 inches
thick. The subsoil extends to a depth of about 80
inches. From a depth of 8 to 16 inches, it is dark
grayish brown clay; from a depth of 16 to 28 inches,
it is yellowish red sandy clay; from a depth of 28
to 37 inches it is strong brown, sandy clay loam;
from a depth of 37 to 48 inches, it is yellowish
brown, sandy clay loam; and from a depth of 48
to 80 inches, it is brownish yellow, sandy clay
loam.
Of minor extent in this map unit are the Bryde,
Gillett, and Papalote soils. The Bryde soils are in
positions on the landscape similar to those of the
Miguel soils. The Gillett soils are in higher positions.
The Papalote soils are in lower positions.
This map unit is used mainly as rangeland, wildlife
habitat, and some improved pasture.
When used as rangeland, these soils produce
moderate yields of forage and are good habitat for
rangeland wildlife. With proper management, a variety
of grasses, forbs, and shrubs can be produced for
livestock and rangeland wildlife. Potential is only fair
for openland wildlife habitat. These soils produce low
to moderate yields on improved pasture. Improved
varieties of bermudagrass and bluestems are the
major grasses grown. The moderate available water
capacity, medium rate of runoff, low natural fertility,
and clayey texture are limitations.
When used as cropland, these soils produce low
to moderate yields. Grain sorghum, corn, wheat,
small grains, and peanuts are the major crops grown.
The moderate available water capacity, medium rate
of runoff, low natural fertility, droughtiness, and
clayey texture are limitations. Water erosion is a
hazard.
