VICTINE SERIES

The Victine series consists of very deep, somewhat poorly drained, very slowly permeable soils that formed in clayey fluviomarine sediments derived from the Beaumont Formation of Late Pleistocene age. These nearly level soils are on low flats on the South Texas Coastal Plain. Slopes range from 0 to 1 percent. Mean annual air temperature is about 22 degrees C (72 degrees F) and mean annual precipitation is about 838 mm (33 in).

RANGE IN CHARACTERISTICS:
Soil Moisture: An ustic soil moisture regime. The soil moisture control section is from 10 to 30 cm (4 to 12 in) below the surface. These soils have cracks in normal years that are 5 mm (1/4 in) or wider through a thickness of 25 cm (10 in) or more within 50 cm (20 in) of the mineral soil surface, for 90 or more cumulative days per year. Typically, cracks remain open between 90 and 120 cumulative days.
These are cyclic soils that have a gilgai microrelief. The distance from the center of the microhigh to the center of the microlow ranges from 91 cm to 183 cm (36 to 72 in). The microhighs are typically calcareous to the surface and have a color similar, or up to 2 values higher than the microlow.
Mean annual soil temperature: 22 to 22.2 degrees C (72 degrees F)

USE AND VEGETATION: Most areas are used for livestock grazing and wildlife habitat. The native plant community consists mostly of grasses such as gulf cordgrass, marshhay cordgrass, seashore saltgrass, hartwig paspalum, little bluestem, vine-mesquite, and buffalograss. A few stunted mesquite trees are in some areas. The ecological site is Salty Prairie, PE 31-44 (150BY551TX).
