Portrero soil series
A representative soil profile of Portrero fine sand, in an area of Potrero-Lopeno-Noria complex, 0 to 5 percent slopes. A buried gleyed soil begins at a depth of about 80 centimeters. A water table is present at this depth. (Soil Survey of Kenedy and Kleberg Counties, Texas; by Nathan I. Haile, and Dennis N. Brezina, Natural Resources Conservation Service)
The Potrero series consists of very deep, somewhat poorly drained, rapid permeable soils deposits on convex linear mounds in deflation flats of active and recently active dune complexes. These nearly level to gently sloping soils formed in sandy eolian sediments of Holocene age overlying loamy eolian deposits of Pleistocene age. Slope ranges from 0 to 3 percent. Mean annual temperature is about 23 degrees C (73 degrees F) and mean annual precipitation is about 686 mm (27 in).
TAXONOMIC CLASS: Mixed, hyperthermic Aquic 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. A water table occurs at a depth of 31 to 91 cm (12 to 36 in) for at least two months in most years. November through April are the driest months, with a second dry period in July. September is the wettest month.
Mean annual soil temperature: 23 to 24 degrees C (74 to 76 degrees F)
Depth to masses of iron accumulations: 0 to 51 cm (0 to 20 in)
Depth to iron depletions or depleted matrix: 61 to 99 cm (24 to 39 in)
Depth to endosaturation: 31 to 91 cm (12 to 36 in) for at least two months in normal years
USE AND VEGETATION: Used for livestock grazing and wildlife habitat. Native vegetation is dominantly gulfdune paspalum. Other vegetation consists of seacoast bluestem, broomsedge bluestem, mistflower, false indigo and burhead. The ecosite is Low Coastal Sand range site, (R150BY650TX).
DISTRIBUTION AND EXTENT: Gulf Coast Saline Prairie (MLRA 150B in LRR T) of southern Texas. The series is of moderate extent. The series was formerly included in the Mustang series. The series was separated based on the presence of a buried soil. Classification changed from Aquic Arenic Paleustalfs to Aquic Ustipsamments 10/2005 based on typifying pedon and supporting documentation.
