TYPE LOCATION: Santa Fe County, New Mexico, about 6.5 miles south-southeast of White Lakes; 1010 feet west and 315 feet south of the northeast corner of section 10, T.10N., R.11E; USGS 7.5 minute topographic quadrangle; Latitude 35 degrees 06 minutes 45.8 seconds North and Longitude 105 degrees 45 minutes 11.2 seconds West, NAD 27.
RANGE IN CHARACTERISTICS:
Soil moisture - The soil moisture control section (SMCS) is intermittently moist in some part from July to October and December to March. Additional run-on occurs from July through September. The soils are driest in May and June. The soil moisture regime is aridic bordering on ustic.
Soil temperature - 51 to 53 degrees F.
Depth to base of mollic epipedon - 60 inches
Depth to base of argillic horizon - 60 inches
Particle-size control section weighted averages:

COMPETING SERIES: These are the Goshen, Hall, Johnston, Kuma, Lazarus, Mobridge, Simpatico, and Zepol series.
Goshen,
Hall,
Johnston,
Kuma,
Mobridge, and
Simpatico soils occur in the ustic moisture regime and are more moist in the soil moisture control section in spring and early summer. (The Kinsell series is in the ustic aridic moisture regime). In addition, Kuma soils have buried paleosols within 20 inches.
Lazarus soils do not contain visible secondary calcium carbonates in the substratum.
Zepol soils have small amounts of volcanic ash in the coarse silt and fine sand fraction.
GEOGRAPHIC SETTING: Kinsell soils are on flood plains of valley floors. They formed in alluvium derived from sandstone, and shale of the Triassic Age Chinle Formation. Slopes are 0 to 2 percent. Elevation ranges from 6,200 to 7,200 feet. The mean annual precipitation is 12 to 14 inches with about 45 percent falling as rain from high-intensity convective thunderstorms between July and September. These soils receive some additional run-on moisture from flooding. 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, Chilerojo, Clovis, and Frajillo soils. Arojomil soils are moderately deep to a petrocalcic horizon and are on summits and shoulders of undulating plateaus. Chilerojo soils are fine-loamy, very deep to a densic contact, and occur on footslopes. Clovis soils have a calcic horizon and occur on backslopes and footslopes. Frajillo soils are loamy, are shallow to hard sandstone, and are on backslopes and shoulders.
DRAINAGE AND PERMEABILITY: Well drained; low surface runoff; permeability is moderately slow.
USE AND VEGETATION: Kinsell soils are used for livestock grazing and farming. Present vegetation is galleta and blue grama.
DISTRIBUTION AND EXTENT: Kinsell soils are of small extent in the northeastern 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.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon - 0 inches to a depth of about 80 inches. (A, Bt1, Bt2, Btk1, and Btk2 horizons)
Argillic horizon - 2 to about 80 inches. (Bt and Btk horizons)
Pachic feature - 0 inches to a depth of about 80 inches, mollic epipedon (A, Bt1, Bt2, Btk1, and Btk2 horizons).
Classified according to Keys to Soil Taxonomy Tenth Edition, 2006.
ADDITIONAL DATA: The series type location has been sampled for partial characterization by the Soil Survey Laboratory (SSL), Lincoln, NE, as soil survey sample number S-NM-02-049-015; Calcium carbonate equivalence was determined using a field calcimeter.
