Deep, nearly level, clayey soils; on flood plains
This map unit consists mainly of moderately alkaline,
somewhat poorly drained and well drained soils that
have slopes of 0 to 1 percent. This unit makes up about
19 percent of the county.
Trinity soils make up about 56 percent of the unit, and
Frio soils make up 19 percent. Minor soils make up the
rest.
Trinity soils are somewhat poorly drained. They are on
broad bottom lands along the Trinity River and its larger
tributaries. Typically, these soils are dark gray to very
dark gray clay from the surface to a depth of about 45
inches, and they are very dark grayish brown clay to a
depth of 68 inches.Frio soils are well drained. They are on broad bottom
lands along the larger streams. Typically, the surface
layer is very dark grayish brown to dark grayish brown
silty clay about 53 inches thick. To a depth of 74 inches,
the soil is brown silty clay loam.
The minor soils in this map unit are Arents in areas
where sand and gravel have been removed and Gowen,
Ovan, and Seagoville soils on flood plains.
The soils in this map unit are used as cropland and
pasture. The soils that are occasionally flooded have
high potential for grain sorghum and cotton. Those that
are frequently flooded are not suited to cultivation. These
soils have high potential for improved bermudagrass.
Many small areas are stripmined for sand and gravel.
The flood hazard, clayey texture, and very slow and
moderately slow permeability of the soils and the very
