COMPETING SERIES: These are the Beisigl (ND), Blanchard (MT), Seroco (ND), Yecross (SD) and Zilditloi (AZ) series. Beisigl soils have a paralithic contact at depths between 20 to 40 inches. Blanchard and Yecross soils are calcareous. Seroco soils are moist in some or all parts of the soil moisture control section during May and June. Zilditloi soils have soil temperatures of 42 to 45 degrees F. and are moist in the soil moisture control section during May.
GEOGRAPHIC SETTING: Kenray soils are formed in eolian sediments on dunes and mesas. Slopes are 3 to 15 percent. Elevations range from 7,300 to 8,000 feet. The peak period of precipitation is from July to October. The mean annual precipitation is 16 to 20 inches and the mean annual air temperature is 44 to 47 degrees F. The frost-free period is 90 to 110 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Pinitos, Ribera and Stout series. Pinitos and Ribera soils have argillic horizons and Stout soils have a lithic contact within 20 inches.
DRAINAGE AND PERMEABILITY: Excessively drained; slow runoff; rapid permeability.
USE AND VEGETATION: These soils are used for wood products and livestock grazing. Present native vegetation is ponderosa pine with scattered grasses and shrubs.
DISTRIBUTION AND EXTENT: The series is of small extent in west central New Mexico. MLRAs 35 & 39.
