The Shanta series is a member of the fine, loamy, mixed, mesic family of Cumulic Haplustolls.
Typically, Shanta soils have thick dark colored loamy A horizons and stratified calcareous C horizons
that average sandy clay loam.
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Cumulic Haplustolls
TYPICAL PEDON: Shanta very fine sandy loam, range. (Colors are for dry soil unless otherwise
noted.)
All--O to 9 inches; brown (lOYR 4/3) very fine sandy loam, dark brown (lOYR 3/3) moist; weak fine
granular structure; soft, very friable, nonsticky, nonplastic; common fine and medium roots; common
fine interstitial and tubular pores; 5 percent gravel; calcareous; mildly alkaline; gradual smooth
boundary. (6 to 12 inches thick)
A12--9 to 23 inches; brown (14YR 4f3}loam, dark brown (14YR 3f3) moist; weak moderate anti coarse
subangular blocky structure; slightly hard, friable, slightly sticky, slightly plastic; common fine and
medium roots; few medium and fine interstitial pores and few fine tubular pores; 10 percent gravel and
cobbles; slightly calcareous; mildly alkaline; gradual smooth boundary. (10 to 15 inches thick)
C2--23 to 50 inches; brown (1 OYR 5/3) light sandy clay loam with thin layers of silt loam, sand and
gravel, dark brown (lOYR 3/3) moist; structureless; slightly hard, friable, slightly sticky, slightly plastic;
few fine and medium roots to 36 inches, few coarse roots; few fine and medium interstitial pores; 10
percent gravel and cobble; moderately calcareous, lime disseminated and segregated as few, f ne, fai .t
segregations; moderately alkaline; diffuse irregular boundary. (24 to 40 inches thick)
IIC2--50 to 60 inches; coarse sand and.gravel.
TYPE LOCATION: Otero County, New Mexico; about 1,000 feet east of the west boundary of the
Mescalero Apache Indian Reservation and about 800 feet south of the road; about 1,000 feet east of the
NW corner of the SW 1/4 section 8, T.11 S., R.1 OE.
RANGE IN CHARACTERISTICS: The mollic epipedon is 20 to 27 inches thick. The mean annual
soil temperature varies from 47 to 59 degrees F. These soils are usually dry in some part between 4 and
12 inches for more than 1/2 the time the soil temperature at 20 inches exceeds 41 degrees F. The driest
period occurs between October and June. The control section ranges from neutral to moderately alakline.
Carbonates range in form from disseminated throughout the control section to common soft lime
concretions, mottles and mycelia in the lower part of the section. Calcium carbonate equivalent is
estimated to range from 5 to 12 percent in the control section. The A horizon has hue of 7.SYR or lOYR,
value of 4 or 5 dry, 2 or 3 moist, and chroma of 2 or 3 dry or moist. Organic matter content of the A
horizon ranges from I to 3 percent and decreases irregularly with depth. The C horizon has hue of
