Pantera soil and landscape

Soil profile: A representative soil profile of Pantera gravelly coarse sandy loam in an area of Melado and Pantera soils, 1 to 5 percent slopes. Pantera soils have very high amounts of rock fragments in the profile. (Soil Survey of Presidio County, Texas; by Ramiro Molina, Natural Resources Conservation Service)

 

Landscape: Pantera soils are mapped with Melado soils and occur on floodplains on alluvial flats. This area also shows in the background, small flat-topped erosion remnants of the Geefour soils. Chinati Mountain is in the far background.

 

The Pantera series consists of very deep, well drained, moderately rapidly permeable soils formed in loamy gravelly alluvial materials. These soils are on nearly level to moderately sloping wide arroyos and drainageways. Slopes range from 0 to 8 percent. The mean annual precipitation is about 10 inches and the mean annual air temperature is about 68 degrees F.

 

TAXONOMIC CLASS: Sandy-skeletal, mixed, hyperthermic Ustic Torrifluvents

 

Soil moisture: intermittently moist in the soil moisture control section during July-September. Ustic aridic soil moisture regime.

Solum thickness: 6 to 15 inches over 40 to 80 inches or more of unconsolidated stratified, loamy, gravelly, or cobbly alluvial materials. The solum and regolith consists of thin to thick bedded layers of gravelly alluvium separated by bedding planes and which vary in content and size of coarse fragments.

Rock fragments: 35 to 80 percent; 25 to 65 percent gravel; 10 to 40 percent cobbles; 0 to 20 percent stones

Texture in the control section: loamy sand, sand, sandy loam

Clay content: 2 to 15 percent

 

In some pedons the coarse fragments in the A and C1 horizons have thin patchy coatings of calcium carbonate, with the carbonate content apparently uniform in these horizons. Some pedons are underlain at 40 to 60 inches or more by various kinds of bedrock, clay, shale, lava, ash, or tuff.

 

USE AND VEGETATION: Used for livestock grazing and wildlife habitat. Has low carrying capacity. Vegetation is mostly a sparse cover of creosotebush, fluffgrass, sixweeks grama, lechugilla, and ocotillo.

 

DISTRIBUTION AND EXTENT: West Texas. MLRA 42. The series is of moderate extent.
