TYPE LOCATION: Socorro County, New Mexico; 14 miles east of San Antonio; 150 feet north and l,500 feet west of the southeast corner of section 34, T. 4 S., R. 3 E.
RANGE IN CHARACTERISTICS:
Soil moisture: The soil moisture control section is intermittently moist in some part from July to September following convective storms. Typic aridic moisture regime.
Clay content - argillic horizon contains 18 to 35 percent clay and has less than 15 percent fine sand and coarser particles.
Depth to the base of the argillic horizon is - 12 to 35 inches.
Depth to the top of the calcic horizon ranges from - 6 to 17 inches, and occurs within or just below the base of the argillic horizon.
Calcium carbonates equivalent - calcic horizon is weakly developed and contains 15 to 20 percent carbonates.
Profile reaction is slightly to moderately alkaline. The profile is calcareous throughout.
Salinity: 0 - 2 mmhos/cm
Organic matter: .9 - 1 percent in the upper 40 cm.
A horizon:
Hue: 5YR or 7.5YR
Value: 5 or 6 dry, 3 or 4 moist
Chroma: 3 or 4
Texture: silty clay loam, clay loam, silt loam or loam
2Btkb or 2Bkb horizons (buried soil):
Value: 5 or 6 dry, 3 or 4 moist
Chroma: 4 to 6
Texture: clay loam, sandy clay loam or loam containing greater than 15 percent fine and coarser sands.
Rock fragments: 0 to 15 percent pebbles
COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING: Barana soils are on nearly level plains and in swales, dominantly in the Jornada del Muerto basin. Barana soils have formed in alluvium derived from many sources. Slopes range from 0 to 3 percent. Elevation ranges from 4,800 to 5,300 feet. The average annual precipitation is 8 to 10 inches and the average annual air temperature is 59 to 64 degrees F. The average frost-free period is 180 to 210 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Berino, Bluepoint, Campana, Dona Ana, Turney and Yesum soils. Berino and Dona Ana soils are fine-loamy and have less organic carbon in the top 40 cm. Bluepoint soils are sandy. Campana and Yesum soils lack argillic horizons and have gypsic horizons. Turney soils lack argillic horizons and are fine-loamy.
DRAINAGE AND PERMEABILITY: Well drained, slow runoff, moderately slow permeability.
USE AND VEGETATION: Barana soils are used for livestock grazing. Present vegetation is alkali sacaton, burrograss, tobosa, sand dropseed and vine-mesquite.
DISTRIBUTION AND EXTENT: Barana soils are moderately extensive in south central New Mexico. MLRA 42.

SERIES ESTABLISHED: Socorro County, New Mexico, 1984.
REMARKS:
Diagnostic horizon and features recognized in this pedon are:
Ochric epipedon The zone from 0 to 3 inches. (A horizon)
Argillic horizon - The zone from about 3 to 17 inches. (Bt and Btk2 horizons)
Calcic horizon - The zone from about 8 to 23 inches. (Btk2 and Bk horizons)
ADDITIONAL DATA: Lab Data from profile S77-NM-028-9, characterized at New Mexico State University, lends support for the presence of an argillic horizon, a weak calcic horizon and placement of this soil in an Ustollic subgroup.
Calcium carbonate equivalence was determined on other selected pedons, including the type location, with use of a field volume calcimeter.
