DALE SERIES


The Dale series consists of very deep, well drained soils that formed in material weathered from loamy alluvium. These soils are on flood plains of minor streams in the Central Rolling Red Prairies (MLRA 80A). Slopes range from 0 to 8 percent. Mean annual air temperature is 16 degrees C (61 degrees F), and mean annual precipitation is 840 mm (33 in).

TAXONOMIC CLASS: Fine-silty, mixed, superactive, thermic Pachic Haplustolls

TYPICAL PEDON: Dale silt loam in a cultivated field, at an elevation of 326 m (1070 ft). (Colors are for dry soil unless otherwise stated.)

Ap--0 to 18 cm (0 to 7 in); dark grayish brown (10YR 4/2) silt loam, very dark grayish brown (10YR 3/2) moist; weak fine granular structure; hard, friable; many fine roots; many worm casts; noneffervescent; neutral; abrupt smooth boundary.

A--18 to 53 cm (7 to 21 in); dark grayish brown (10YR 4/2) silt loam, very dark grayish brown (10YR 3/2) moist; moderate fine and medium granular structure; hard, friable; many fine roots; many worm casts; noneffervescent; neutral; gradual smooth boundary. (Combined thickness of the A horizon is 25 to 66 cm [10 to 26 in])

Bw--53 to 102 cm (21 to 40 in); brown (10YR 4/3) silt loam, dark brown (10YR 3/3) moist; weak coarse prismatic structure parting to moderate medium granular; hard, friable; few fine roots; few worm casts; noneffervescent; slightly alkaline; gradual smooth boundary. (Thickness of the Bw horizon is 25 to 76 cm [10 to 30 in])

BCk--102 to 152 cm (40 to 60 in); brown (7.5YR 5/4) silt loam, brown (7.5YR 4/4) moist; massive; hard, friable; few fine roots; few worm casts; few films and soft masses of calcium carbonate; slightly effervescent; moderately alkaline.

TYPE LOCATION: Lincoln County, Oklahoma; about 1 mile east of Harrah; about 4,000 feet south and 900 feet east of northwest corner of sec. 30, T. 12 N., R. 2 E.

COMPETING SERIES: This is the Buttermilk series in the same family.
Buttermilk soils: have an electrical conductivity of 2 to 16 mmhos/cm throughout the profile

GEOGRAPHIC SETTING:
Parent material: loamy alluvium
Landscape: alluvial plain
Landform: level to sloping flood plains
Slope: 0 to 8 percent
Mean Annual Air Temperature: 15 to 17.2 degrees C (59 to 63 degrees F)
Mean Annual Precipitation: 635 to 1041mm (25 to 41 in)

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brewer, Canadian, Crisfield, Lela, McLain, Port, Reinach and Yahola series.
Brewer, Lela, and McLain soils: have more than 35 percent clay in the control section, are on slightly lower positions farther from the stream
Canadian, Crisfield, and Reinach soils: have less that 18 percent clay in the control section, are on slightly higher positions, and closer to the stream
Port soils: are cumulic and occur on lower positions
Yahola soils: are coarse-loamy and are on slightly lower positions

DRAINAGE AND PERMEABILITY:
Drainage: well drained
Permeability: moderate
Runoff: negligible on 0 to 1 percent slopes; medium on 3 to 8 percent slopes

USE AND VEGETATION: Dominantly cultivated to alfalfa, small grains, grain sorghums, and cotton. Small areas are used for range or tame pastures. Native vegetation is tall and mid grasses with pecan, black walnut, bur oak, and eastern cottonwood trees.

DISTRIBUTION AND EXTENT: Central Oklahoma, and South Central Kansas; LRR H; Central Red Rolling Prairies (MLRA 80A). The series is moderately extensive.
