Atiras soil series
A representative soil profile of Atiras fine sand in an area of Falfurrias-Atiras-Medanito complex, 0 to 5 percent slopes. A thin buried A horizon is at a depth of about 150 centimeters. (Soil Survey of Kenedy and Kleberg Counties, Texas; by Nathan I. Haile, and Dennis N. Brezina, Natural Resources Conservation Service)
The Atiras series consists of very deep, somewhat excessively drained, rapidly permeable soils. These soils formed in sandy eolian deposits of Holocene age over loamy Quaternary alluvium. These soils are on gently undulating eolian plains associated with vegetated longitudinal dunes on the Sandsheet Prairie of the South Texas Coastal Plain. Slope ranges from 1 to 5 percent. Mean annual air temperature is about 23 degrees C (73 degrees F), and mean annual precipitation is about 660 mm (26 in).
TAXONOMIC CLASS: Mixed, hyperthermic Typic Ustipsamments
Soil Moisture: An Ustic moisture regime. The soil moisture control section is dry in some or all parts for more than 90, but less than 150, cumulative days in normal years. The SMCS is also either moist in some or all parts for 180 cumulative days or more, or moist for 90 or more consecutive days in normal years. November through April are the driest months, with a second low in July, while September is the wettest.
Depth to buried soil: 102 to 203 cm (40 to 80 in)
Depth to redox concentrations: 41 to 76 cm (16 to 30 in)
Particle-size control section (weighted average):
Clay content: 9 to 18 percent
Sand content: 80 to 86 percent
USE AND VEGETATION: Used for livestock grazing and wildlife habitat. Native vegetation consists of liveoak, seacoast bluestem, switchgrass, seashore paspalum, Scribner's panicum, partridge pea and turk's cap. The ecological site is Sand, PE 31-44 (R083EY706TX).
DISTRIBUTION AND EXTENT: Sandsheet Prairie (MLRA 83E in LRR I) of southern Texas. The series is of moderate extent.
