RANGE IN CHARACTERISTICS:
Soil moisture - The soil moisture control section is intermittently moist in some part from July to October and December to March. It is assumed to be dry in all parts 50 to 75 percent of the time (cumulative), when the soil temperature at 20 inches is 41 degrees F. or higher. The soils are driest in May and June. The soil moisture regime is ustic aridic .

COMPETING SERIES: These are the Alvey, Barx, Cabreros, Cerrillos, Clovis, Fernando, Flaco, Horchata, Maysdorf, Millett, Progresso, Sanostee, Schollee, Selpats, Solirec, Spenlo, Threetop, Tuweep, and Wineg soils.
Alvey,
Barx,
Cerrillos,
Clovis,
Fernando,
Maysdorf,
Millett, Schollee,
Selpats,
Solirec,
Spenlo,
Tuweep, and
Wineg soils are very deep.
Flaco,
Horchata,

Sanostee, and
Threetop soils are moderately deep to bedrock.
GEOGRAPHIC SETTING: Palabria soils are on structural benches. They formed in eolian material derived from sandstone and shale and residuum derived from sandstone. Slopes are 1 to 8 percent. Elevation ranges from 6,400 to 7,100 feet. The mean annual precipitation is 12 to 14 inches. The mean annual air temperature is 49 to 51 degrees F. The frost-free period is 130 to 150 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Arojomil, Clovis, Frajillo, and Tapia soils. Arojomil soils are moderatley deep to petrocalcic horizons. Clovis soils are very deep and occur on adjacent undulating plateaus. Frajillo soils are shallow and do not have calcic horizons. Tapia soils have petronodes and occur on adjacent undulating plateaus.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately slow permeability.
USE AND VEGETATION: Palabria soils are used for livestock grazing, wildlife habitat, and recreation. Native vegetation is Bigelow's sagebrush, blue grama, and broom snakeweed.
DISTRIBUTION AND EXTENT: Palabria soils are of small extent in the northerneastern part of the Estancia Basin in the Mexican Highland section of the Basin and Range physiographic province in northcentral New Mexico, MLRA 70C.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Phoenix, Arizona.
