Brownfield soil series

(Soil Survey of Yoakum County, Texas, Natural Resources Conservation Service)
The Brownfield series consists of very deep, well drained, moderately permeable soils derived from sandy eolian deposits from the Blackwater Draw Formation of Pleistocene age. Brownfield soils are on nearly level to gently sloping plains. Slope ranges from 0 to 5 percent. The mean annual precipitation is about 457 mm (18 in) and the mean annual air temperature is about 16 degrees C (61 degrees F).
TAXONOMIC CLASS: Loamy, mixed, superactive, thermic Arenic Aridic Paleustalfs
Soil moisture: An ustic moisture regime bordering on aridic. The soil moisture control section is dry in some or all parts for more than 180 but less than 220 days, cumulative, in normal years. July through August and December through February are the driest months. These soils are intermittently moist in September through November and March through June.
Mean annual soil temperature: 15 to 18 degrees C (59 to 64 degrees F).
Depth to argillic horizon: 51 to 102 cm (20 to 40 in).
Depth to calcic horizon: typically greater than 2 m (6.6 ft) but ranges from 150 to more than 203 cm (60 to 80 in).
Solum thickness: more than 203 cm (80 in).
Particle-size control section: 18 to 35 percent silicate clay.
USE AND VEGETATION: Mainly used for cropland but also used as native rangeland. Principal crops grown are cotton and grain sorghum. Climax vegetation is tall and mid grasses, with tall grasses tending to dominate. This site is dominated by little and sand bluestem along with taller dropseed species. The remainder is mid and short grasses such as sideoats grama, sand dropseed, hooded windmillgrass, sand lovegrass, sand paspalum, fall witchgrass, hairy grama, needle and thread, and perennial threeawn. Sand sage, shinoak, and skunkbush are also present. This soil has been correlated to the Sandy (R077CY035TX) ecological site in MLRA-77C.
DISTRIBUTION AND EXTENT: Southern High Plains of western Texas and eastern New Mexico (sub-MLRA-77C). The series is extensive.
