Veleno soil series
A representative soil profile of Veleno clay loam, 0 to 2 percent slopes. A clayey natric horizon begins at a depth of 15 centimeters and extends throughout the solum. Natric horizons have accumulations of sodium. (Soil Survey of Zapata County, Texas; by Ramiro Molina and Roel D. Guerra, Jr., Natural Resources Conservation Service)
The Veleno series consists of very deep, moderately well drained, very slowly permeable soils that formed in calcareous, saline, clayey alluvium. These nearly level to gently sloping soils are on drainageways. Slope ranges from 0 to 2 percent. Mean annual temperature is about 23 degrees C (73 degrees F) and mean annual precipitation is about 533 mm (21 in).
TAXONOMIC CLASS: Fine, mixed, active, hyperthermic Halic Haplusterts
Solum thickness is more than 203 cm (80 in).
Soil Moisture: An ustic bordering on aridic soil moisture regime. The soil moisture control section, 8 to 24 inches, is moist in some or all parts for less than 90 consecutive days in normal years.
Mean annual soil temperature: 22 to 23 degrees C (72 to 74 degrees F).
Depth to secondary calcium carbonate: 61 to 127 cm (24 to 50 in)
Particle-size control section (weighted average)
Clay content: 40 to 60 percent
USE AND VEGETATION: Used mainly as rangeland and wildlife habitat. The native vegetation consists of four-flower trichloris, Arizona cottontop, Plains bristlegrass, hooded windmillgrass, pink pappusgrass and woody shrubs such as mesquite, pricklypear, Texas ebony, tasajillo, and spiny hackberry. The ecological site is Saline Clay 18-25 PZ(R083BY432TX).
DISTRIBUTION AND EXTENT: Western Rio Grande Plains, Texas, LRR I; MLRA 83B; the series is of moderate extent. These soils were formerly included in the Montell series. The Montell series typically are not mapped in floodplains. This series will be used for areas mapped as Montell flooded in published soil surveys.
