WOOZLE SERIES
The Wozle series consists of very deep, well drained soils that formed in mixed alluvium. They are on alluvial terraces and have slopes of 0 to 1 percent. The mean annual precipitation is about 10 inches, and the mean annual temperature is about 49 degrees F.
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Xeric Calciargids
TYPICAL PEDON: Woozle loam, cultivated. (Colors are for air dry soil unless otherwise noted.)
Ap--0 to 10 inches; brown (10YR 5/3), pale brown (10YR 6/3 crushed) loam, dark brown (10YR 3/3), dark grayish brown (10YR 4/2 crushed) moist; weak very fine subangular blocky structure parting to very weak very fine granular; slightly hard, friable, slightly sticky and slightly plastic; common very fine and fine roots; many very fine and common fine tubular pores; common worm channels and casts; slightly alkaline (pH 7.4); abrupt smooth boundary. (6 to 12 inches thick)
Bt--10 to 21 inches; brown (10YR 5/3), pale brown (10YR 6/3 crushed) loam, dark brown (10YR 3/3), brown (10YR 4/3 crushed) moist; weak medium and fine subangular blocky structure; hard, friable, slightly sticky and slightly plastic; common very fine and fine roots; many very fine and few fine tubular pores; few worm channels and casts; common faint clay films on faces of peds and in pores; noneffervescent matrix with some worm channels filled with light gray strongly effervescent material; slightly alkaline (pH 7.4); abrupt smooth boundary. (7 to 18 inches thick)
2Bk1--21 to 35 inches; light gray (10YR 7/2) silt loam, brown (10YR 5/3) moist; weak fine and medium subangular blocky structure; hard, friable, slightly sticky and slightly plastic; common very fine and fine roots; common very fine and few fine tubular pores; few krotovinas; strongly effervescent, few fine lime veins and soft masses; moderately alkaline (pH 8.0); clear smooth boundary. (0 to 15 inches thick)
3Bk2--35 to 42 inches; very pale brown (10YR 8/2) loam, pale brown (10YR 6/3) moist; very weak fine and medium subangular blocky structure; hard, friable, slightly sticky and slightly plastic; common very fine and fine roots; many very fine tubular pores; few rounded krotovinas; strongly effervescent, few fine and medium veins and soft masses of lime; moderately alkaline (pH 8.0); abrupt smooth boundary. (6 to 10 inches thick)
4Bk3--42 to 47 inches; light gray (10YR 7/2) loamy fine sand, brown (10YR 5/3) moist; massive; soft, very friable, nonsticky and nonplastic; few very fine roots; many very fine irregular and few very fine tubular pores; common worm channels and casts; strongly effervescent, few lime veins; moderately alkaline (pH 8.2); clear smooth boundary. (0 to 10 inches thick)
5C--47 to 60 inches; light brownish gray (10YR 6/2) fine sand, dark grayish brown (10YR 4/2) moist; single grain; loose; few very fine and fine roots; many irregular pores; slightly effervescent; moderately alkaline (pH 8.1).
TYPE LOCATION: Minidoka County, Idaho; 1 mile east and 2 miles north of the sugar factory in Paul, Idaho; 290 feet north and 660 feet west of the southeast corner of the northeast 1/4, section 15, T. 9 S., R. 23 E.
RANGE IN CHARACTERISTICS:
Depth to sand - 40 to 60 inches
Depth to bedrock - more than 60 inches
Mean annual soil temperature - 50 to 51 degrees F.
Control section - 24 to 32 percent clay - 15 to 45 percent fine and medium sand and 0 percent rock fragments
Texture - L, CL, or SICL
Depth to calcic horizon - 15 to 30 inches
Calcium carbonate equivalent - 15 to 30 percent
Soil moisture - soils are usually dry but are moist between depths of 4 and 12 inches for 50 to 70 days in the spring and early summer
BA horizons are present in some pedons
A horizons
Value -5 or 6 dry, 3 or 4 moist

Calcium carbonate equivalent - 15 to 30 percent
C horizons
Value - 5 to 7 dry, 3 to 5 moist
Chroma - 1 or 2
Texture - FS, SL, LFS, or GR-S

COMPETING SERIES: These are the
Dixie,
Paulville and
Sevy series. Dixie soils have 15 to 35 percent gravel and cobbles in the particle-size control section. Paulville soils are loamy throughout the profile and lack the sandy substratum material. Sevy soils have hues of 7.5YR or 5YR in the argillic horizons.
GEOGRAPHIC SETTING: Woozle soils are on alluvial terraces. Slopes range from 0 to 1 percent. Elevations range from 4,145 to 4,155 feet. The soils formed in mixed alluvium. The climate is semiarid; the mean annual temperature is 48 to 49 degrees F., and the mean annual precipitation is 8 to 10 inches. The frost free season ranges from 130 to 140 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Eoyote and
Portneuf, soils. Eoyote and Portneuf soils lack an argillic horizon, and have less than 18 percent clay in the control section. Eoyote soils have sandy loam textures throughout. Eoyote and Portneuf soils are on higher terraces.
DRAINAGE AND PERMEABILITY: Well drained, slow or medium runoff. Moderately slow permeability.
USE AND VEGETATION: Used for irrigated crops. The irrigated crops grown include alfalfa, beans, small grains, pasture, sugar beets, and potatoes. The potential natural vegetation is Wyoming big sagebrush, bluebunch wheatgrass, Thurber needlegrass and Sandberg bluegrass.
DISTRIBUTION AND EXTENT: South central Idaho. These soils are moderately extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Portland, Oregon
SERIES ESTABLISHED: Minidoka County, Idaho, 1999.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon
Argillic horizon - The zone from 10 to 21 inches (Bt horizon)
Particle-size control section - The zone from 10 to 21 inches (Bt horizon)
Calcic horizon - The zone from 21 to 42 inches (2Bk1 and 2Bk2 horizons)
During the update of the Minidoka soil survey, the Paulville series was split into two series. The soil having sand textures below 40 inches is correlated to a new series Woozle. The Paulville series was dominantly loamy below 40 inches and the Paulville series type location was moved.
