Mansker soil series
The Mansker series consists of very deep, well drained, moderately permeable soils that formed in loamy, calcareous eolian deposits of the Blackwater Draw Formation of Pleistocene age. These soils are on nearly level to moderately sloping plains. Slope ranges from 0 to 8 percent. The mean annual precipitation is 483 mm (19 in) and the mean annual temperature is 16 degrees C (60 degrees F).
TAXONOMIC CLASS: Coarse-loamy, carbonatic, thermic Calcidic 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).
Mollic epipedon thickness: 18 to 30 cm (7 to 12 in)
Depth to argillic horizon: 25 to 76 cm (10 to 30 in).
Depth to calcic horizon: 15 to 60 cm (6 to 24 in).
Percent calcium carbonate by weight in control section: 40 to 60 percent
Particle-size control section: 10 to 18 percent silicate clay
Solum thickness: more than 203 cm (80 in).
Note: total clay content ranges from 18 to 35 percent in the particle-size control section; the taxonomic family particle-size class excludes clay-size carbonates in classification.
USE AND VEGETATION: Primarily used for rangeland. Where cultivated, the principal crops are grain sorghum, small grains, and forage crops. Climax vegetation 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 prairie clover with a light to moderate overstory of mesquite. This soil has been correlated to the Limy Upland (R077CY028TX) ecological site in MLRA-77C.
DISTRIBUTION AND EXTENT: Texas, New Mexico, and Oklahoma in the Southern High Plains (MLRA 77C in LRR H). The series is of moderate extent. Series Revised MLRA-77 Soil Survey update in Floyd County, Texas; 2004. After review of the lab data, the taxonomic family particle-size class was changed from fine-loamy to coarse-loamy in 2008.
