COMPETING SERIES: These are the Bacobi (AZ), Frisite (WY), Grazane (AZ), Griffy (WY), Neiber (WY), Papoose (NV), Redlands (CO), Saddle (WY), Starmountain (AZ) and Tijeras (NM) series. Bacobi, Grazane, Neiber and Saddle soils have a paralithic contact between 20 and 40 inches. Frisite, Griffy, Papoose, Redlands, Starmountain and Tijeras soils are greater than 40 inches deep.
GEOGRAPHIC SETTING: Kiki soils are on knolls and ridges. Slopes are 3 to 15 percent. The soil formed in sediments derived from mixed alluvial and eolian material. Elevation is 5,500 to 6,000 feet. Mean annual precipitation is 7 to 10 inches. Mean annual temperature ranges from 51 to 55 degrees F. The frost-free period is 140 to 165 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are Mack, Navajo, Shiprock and Suwanee soils. These soils have depths greater than 40 inches.
DRAINAGE AND PERMEABILITY: Well drained; slow to medium runoff; moderate permeability.
USE AND VEGETATION: These soils are used for livestock grazing and urban development. Principal native vegetation is galleta, rubber rabbitbrush, prickly pear and yucca.
DISTRIBUTION AND EXTENT: West central New Mexico. The series is of small extent. MLRA 42.
