COMPETING SERIES: This is the Poblano series (NM). Poblano soils are moderately deep.
GEOGRAPHIC SETTING: Sanloren soils are at elevations of 5,500 to 6,500 feet, on stream terrace remnants along the major streams. Slopes range from 0 to 10 percent. These soils formed in mixed alluvium. The climate is semiarid continental. The mean annual precipitation is about 12 to 16 inches and the mean annual temperature is 47 to 55 degrees F. The frost free season ranges from 150 to 180 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Ellicott, Lonti, Majada, Manzano, Oro Grande, and Paymaster soils. Ellicott and Lonti soils do not have a mollic epipedon. Majada soils have a loamy, skeletal control section. Manzano soils have a fine, loamy control section. Oro Grande soils are shallow to bedrock. Paymaster soils have a coarse, loamy control section.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately slow permeability.
USE AND VEGETATION: Used primarily for range. Native vegetation is mainly blue grama, sideoats gram, little bluestem, yucca, juniper, and pinyon.
DISTRIBUTION AND EXTENT: Northern Grant County, New Mexico. Sanloren soils are of small extent. MLRA 38.
