WELEETKA SERIES


The Weleetka series consist of very deep, very poorly drained, moderately slowly permeable soils on side slopes of forested eolian reworked terraces on uplands of the Arkansas Valley and Ridges Western (MLRA 118B) that formed in thick beds of sandy material. These very gently sloping to strongly sloping soils are on side slopes that are parallel to drainageways and stream channels. Slopes range from 2 to 12 percent. Mean annual precipitation is 39 inches. Mean annual air temperature is 61 degrees F.

TAXONOMIC CLASS: Coarse-loamy, mixed, subactive, thermic Typic Endoaquults

TYPICAL PEDON: Weleetka sandy loam on a 2 percent slope--rangeland. (Colors are for moist soils unless otherwise stated.)

A--0 to 8 inches; very dark gray (10YR 3/1), dark gray (10YR 4/1) dry; sandy loam; few medium prominent strong brown (7.5YR 5/6) redoximorphic concentration masses along root channels; moderate medium granular structure; friable; very strongly acid; gradual smooth boundary. (6 to 17 inches thick)

Eg1--8 to 17 inches; dark gray (10YR 4/1) sandy loam; strong medium subangular blocky structure; firm, peds are brittle; few fine prominent dark yellowish brown (10YR 3/4) redoximorphic concentration masses along root channels; strongly acid; clear smooth boundary. (6 to 14 inches thick)

Eg2--17 to 42 inches; dark grayish brown (10YR 4/2) loamy sand; single grained; loose; common medium faint dark gray (10YR 4/1) and brown (10YR 4/3) redoximorphic depletions; strongly acid; gradual smooth boundary. (8 to 27 inches thick)

Btg--42 to 54 inches; gray (10YR 5/1) sandy loam; moderate medium subangular blocky structure; firm; common medium prominent strong brown (7.5YR 4/6) and few fine prominent reddish brown (5YR 4/4) redoximorphic concentrations; strongly acid. (10 to 18 inches thick)

2C--54 to 80 inches; pale brown (10YR 6/3) sand; single grained; loose; common coarse distinct light gray (10YR 7/1) redoximorphic concentrations; slightly acid.

TYPE LOCATION: Okfuskee County, Oklahoma; about 1,300 feet east and 300 feet south of the northwest corner of Sec. 13, T. 10 N., R. 9 E.

RANGE IN CHARACTERISTICS: The solum thickness is 40 to more than 60 inches.

The A horizon has hue of 10YR, value of 3 or 4, and chroma of 1 or 2. Texture is loamy fine sand or sandy loam. It has redoximorphic iron depletions in shades of gray and redoximorphic iron concentrations in shades of red or brown. Reaction ranges from very strongly acid to moderately acid.

The Eg1 and Eg2 horizons have hue of 7.5YR or 10YR, value of 3 to 7, and chroma of 1 or 2. Texture is loamy fine sand, loamy sand, sandy loam. It has redoximorphic iron depletions in shades of gray and redoximorphic iron concentrations in shades of red or brown. Reaction is strongly acid or moderately acid.

The Bt horizon has hue of 7.5YR or 10YR, value of 4 to 7, and chroma of 1 or 2. It has common distinct or prominent redoximorphic concentration masses in shades of yellow, brown, and red. Texture is sandy loam or loam. Reaction ranges from very strongly acid to moderately acid.

The 2C horizon has a hue of 7.5YR or 10YR, value of 6 or 7, and chroma of 1 to 4. Texture is sand or loamy sand. It has redoximorphic iron depletions in shades of gray and redoximorphic iron concentrations in shades of red or brown. Reaction ranges from very strongly acid to slightly acid.

COMPETING SERIES: There are no other series in the family.

GEOGRAPHIC SETTING: Weleetka soils are on very gently sloping to strongly sloping side slopes of forested eolian terraces on uplands. These soils formed in thick beds of sandy material. Slopes range from 2 to 12 percent. Mean annual precipitation ranges from 36 to 42 inches. Mean annual temperature ranges from 59 to 63 degrees F. Thornthwaite annual P-E indices range from 60 to 72.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Glentosh, Larton, and Porum soils. Glentosh soils have A horizons more than 20 inches thick, have a sandy control section, and occur on slightly higher landscapes. Larton soils are on higher terraces and have sola that do not decrease more than 20 percent in clay content from the maximum in the Bt2 horizons and have A horizons more than 20 inches thick. Porum soils occur on higher terraces and have a fine particle-size control section.

DRAINAGE AND PERMEABILITY: Weleetka soils are very poorly drained; runoff ranges from negligible to medium; and permeability is moderately slow. This soil is saturated with water from 0 to 3 feet for most of the year.

USE AND VEGETATION: Used mainly for rangeland. Native vegetation is Little Bluestem, Indiangrass, Broomsedge, Panicums, and other prairie grasses with an overstory of woody species such as Blackberry, Winged Elms, Sumac, and Willows.

DISTRIBUTION AND EXTENT: East Central and Eastern Oklahoma. The series is of small extent.
