LOCATION KETTNER NMInactive Series
TAXONOMIC CLASS: Loamy, mixed, superactive, nonacid, frigid, shallow Typic Ustorthents
TYPICAL PEDON: Typical profile of Kettner loam, in an area of cutover ponderosa pine. (Colors are for dry soil unless otherwise noted.)
01&02-- inch to 0, needles and leaves, in various stages of decomposition.
A11--0 to 4 inches, dark grayish brown (10YR 4/2) loam, very dark grayish brown (10YR 3/2) when moist; weak, fine, granular structure; soft when dry, friable when moist, nonsticky and nonplastic when wet; about 10 percent of horizon is gravel; pH 6.3; clear boundary.
A12--4 to 8 inches, brown (10YR 5/3) loam, dark brown (10YR 3/3) when moist; weak, fine, granular structure; slightly hard when dry, friable when moist, nonsticky and nonplastic when wet; pH 6.4; clear boundary.
C--8 to 17 inches, brown (7.5YR 5/4) loam, dark brown (7.5YR 4/4) when moist; weak, fine, subangular blocky structure; hard to very hard when dry, firm when moist, slightly sticky and slightly plastic when wet; plentiful medium pores; pH 6.8; gradual boundary.
C/R--17 to 22 inches, mixture of yellowish brown (10YR 5/4) sandy loam and fragments of schist, dark brown (7.5YR 4/4) when moist; massive; hard when dry, firm when moist, nonsticky and nonplastic when wet; pH 7.0; abrupt boundary.
R--22 inches +, schist.
TYPE LOCATION: SW1/4 sec. 33, T. 12 N., R. 14 W., Valencia County, New Mexico:
RANGE IN CHARACTERISTICS: The depth to weathered schist is commonly 15 to 20 inches, but it may be as little as 13 inches in places. Although loam is the dominant texture of the surface layer, the texture is sandy loam or gravelly loam in places. The texture of the substratum is loam or sandy loam. The color ranges from 10YR to 7.5YR in hue. The soil colors are inherited from the parent schist.
COMPETING SERIES: This is the Krakon (NM) series.
GEOGRAPHIC SETTING: The Kettner series consists of shallow, well-drained, noncalcareous soils on gently undulating uplands. The slope range is 3 to 20 percent. These soils developed over schist. They occur at elevations of 8,100 to 8,300 feet, where the annual precipitation is 18 to 20 inches and the average annual temperature is 44? F.
GEOGRAPHICALLY ASSOCIATED SOILS: The Kettner soils are associated with the Mirabal and Zuni soils. They lack the strong granitic influence of the Mirabal soils and the coarse fragments in the substratum. They are not as deep as the Zuni soils, and they lack a distinct B2 horizon.
DRAINAGE AND PERMEABILITY: Well drained, moderate permeability.
USE AND VEGETATION: The vegetation is Ponderosa pine, oak brush, Arizona fescue, pine dropseed, blue grama, mullein, snakeweed, rabbitbrush, and gooseberry.
DISTRIBUTION AND EXTENT: Zuni Mountain Area, New Mexico. MLRA 35.

REMARKS: This description was added to the OSD database in March 2007. The intent is to preserve the concept of the series. The information in this description is taken verbatim from the Soil Survey of Zuni Mountain Area, New Mexico published in 1967. No update was made to the typical pedon nomenclature, geographically associated soils, etc.
