Estacado soil series
(Soil Survey of Deaf Smith County, Texas by Thomas C. Byrd, Natural Resources Conservation Service; photo by Kelly Auttebury and Earl Blakley)
The Estacado series consists of very deep, well drained, moderately slowly permeable soils that formed in calcareous, loamy eolian deposits of the Blackwater Draw Formation of Pleistocene age. These soils are on nearly level to gently sloping plains and playa slopes. Slope ranges from 0 to 5 percent. Mean annual precipitation is 483 mm (19 in), and mean annual air temperature is 16 degrees C (61 degrees F).
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, thermic Aridic Paleustolls
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: 13 to 25 cm (5 to 10 in).
Depth to secondary calcium carbonate: 13 to 61 cm (5 to 24 in).
Depth to calcic horizon: 63 to 100 cm (25 to 40 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 crop production. Principal crops grown are cotton, grain sorghum, and wheat. Climax vegetation in rangeland is mainly mid and short grasses and includes blue grama, sideoats grama, and buffalograss, with lesser amounts of vine-mesquite, western wheatgrass, galleta or tobosa, silver bluestem, wild alfalfa, and prairieclover with a light to moderate overstory of mesquite. This soil has been correlated to the Deep Hardland (R077CY022TX) ecological site in MLRA-77C.
DISTRIBUTION AND EXTENT: The Southern High Plains, Southern Part (MLRA 77C in LRR H) of western Texas and eastern New Mexico. The soil is moderately extensive. These soils were previously included with the Portales and Mansker series.
