Ships soil series
A representative soil profile of the Ships soil series. (Soil Survey of Robertson County, Texas; By Harold W. Hyde, Natural Resources Conservation Service).
The Ships series consists of soils that are very deep to clayey alluvium derived from calcareous shale formed from Permian age red bed sediments. They are moderately well drained and very slowly permeable. These soils are nearly level to gently sloping and occur on flood plains of river valleys. The slope range is 0 to 5 percent. Mean annual precipitation is about 1006 mm (40.0 in) and the mean annual air temperature is about 18.7 degrees C (66.0 degrees F).
TAXONOMIC CLASS: Very-fine, mixed, active, thermic Chromic Hapluderts
Soil Moisture: Udic soil moisture regime. The soil moisture control section is 10 to 30 cm. Soil is not dry in any part of the soil moisture control section for more than 90 cumulative days in normal years.
Mean annual soil temperature: 19.8 to 21.6 degrees C (65 to 71 degrees F)
Soil Depth: very deep, greater than 203 cm (80 in)
Thickness of ochric epipedon: 15 to 76 cm (6 to 30 in)
Depth to secondary carbonates: 38 to 107 cm (15 to 42 in)
Vertic features: 5 to 50 percent slickensides starting at a depth of 15 to 61 cm (6 to 24 in); cracks at least 1 cm (0.4 in) wide extend from the surface to a depth of more than 20 inches when the soil is dry. Cracks are open for 60 to 90 cumulative days during most years.
COLE: 0.05 to 0.11
Particle-size control section (weighted average)
Clay content: 60 to 70 percent
Rock fragments: 0 to 1 percent siliceous pebbles
Exchangeable sodium: 2 to 8 percent
Base Saturation: 100 percent
USE AND VEGETATION: Mainly used as cropland. Crops include cotton, corn, grain sorghum, small grain, and some improved pastures of bermudagrass, johnsongrass, or small grain. Native vegetation includes big bluestem, little bluestem, Indiangrass, switchgrass, Virginia wildrye, and beaked panicum. Adjacent to stream channels ash, elm, and pecan are the dominant trees.
DISTRIBUTION AND EXTENT: General area: South Central Texas (mainly along the Colorado and Brazos Rivers) Land Resource Region: J - Southwestern Prairies Cotton and Forage Region Major Land Resource Area: 86A - Texas Blackland Prairie, Northern Part
Extent: moderate--these soils were formerly included in the Miller series.
SERIES ESTABLISHED: Bastrop County, Texas, 1973.
