YAHOLA SERIES

The Yahola series consists of very deep, well drained, moderately rapidly permeable soils formed in calcareous loamy alluvium of Permian and Pleistocene age. These soils are on nearly level flood plains of major streams in the Central Rolling Red Prairies (MLRA 80A). Slope ranges from 0 to 2 percent. Mean annual air temperature is 16 degrees C (61 degrees F), and mean annual precipitation is 790 mm (31 in).

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, calcareous, thermic Udic Ustifluvents

TYPICAL PEDON: Yahola fine sandy loam, in cultivated field, at an elevation of 256 m (840 ft). (Colors are for dry soil unless otherwise stated.)

Ap--0 to 28 cm (0 to 11 in); reddish brown (5YR 5/4) fine sandy loam; reddish brown (5YR 4/4) moist; weak fine granular structure; soft, very friable; very slightly effervescent; moderately alkaline; gradual smooth boundary. (Thickness of the Ap horizon is 10 to 51 cm [4 to 20 in])

C1--28 to 102 cm (11 to 40 in); reddish yellow (5YR 6/6) fine sandy loam; yellowish red (5YR 5/6) moist; massive; slightly hard, very friable; thin strata of loamy fine sandy and silt loam in the lower part; slightly effervescent; moderately alkaline; gradual smooth boundary.

C2--102 to 142 cm (40 to 56 in); reddish brown (5YR 5/4) loam; reddish brown (5YR 4/4) moist; massive; slightly hard, friable; slightly effervescent; moderately alkaline; gradual smooth boundary. (Combined thickness of the C horizon is 152 to 193 cm [60 to 76 in])

C3--142 to 183 cm (56 to 72 in); yellowish red (5YR 5/6) stratified loamy fine sand through loam, yellowish red (5YR 4/6) moist; massive; slightly hard, very friable; slightly effervescent; moderately alkaline.

TYPE LOCATION: Jefferson County, Oklahoma; about 7 miles west and 1 mile north of Ryan; about 1,989 feet north and 800 feet east of the southwest corner of sec. 18, T. 6 S., R. 8 W .

Ap horizon:
Hue: 2.5YR to 7.5YR

Chroma: 2 to 6 dry or moist
Other features: where the A horizon moist value is 5 or less, and chroma is 3 or less, and thickness is more than 25 cm (10 in), organic matter content is less than 1 percent
Texture: loamy fine sand, fine sandy loam, very fine sandy loam, or loam
Textures features: where the loamy fine sand occurs, it is less than 30 cm (12 in) thick
Effervescence: none to slight
Reaction: slightly alkaline or moderately alkaline in the upper 25 cm (10 in) and moderately alkaline below 25 cm (10 in)

C horizon:
Hue: 2.5YR to 7.5YR
Value: 6 or 7 dry, 5 or 6 moist
Chroma: 3 to 8 dry or moist
Texture above 102 cm (40 in): fine sandy loam, very fine sandy loam, or loam with 5 to 18 percent clay
Texture below 102 cm (40 in): loamy fine sand, fine sandy loam, loam, or silt loam
Stratification: thin strata of coarser or finer materials occur throughout the C horizon
Effervescence: none to slight
Reaction: moderately alkaline

COMPETING SERIES: There are no other series in the same family. Similar soils are the Gaddy and Gracemont.
Gaddy soils: have a sandy textural control section
Gracemont soils: have redoximorphic features in the upper part of the profile

GEOGRAPHIC SETTING:
Parent material: formed in calcareous loamy alluvium
Landscape: alluvial plains
Landform: flood plains along major streams
Slope: 0 to 2 percent
Mean annual precipitation: 533 to 1041 mm (26 to 40 in)
Mean annual air temperature: 13.9 to 17.2 degrees C (57 to 63 degrees F)
Frost-free period: 190 to 230 days
Elevation: 280 to 525 meters (920 to 1720 ft)
Thornthwaite Annual P-E indices: 44 to 64

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Canadian, Dale, Gaddy, Gracemont, Gracemore, and Reinach series.
Canadian and Dale soils: have a mollic epipedon and are on slightly higher positons
Gaddy soils: have a sandy control section and are in slightly lower positions Gracemont and Gracemore soils: have a water table within 102 cm (40 in) of the soil surface and are in slightly lower positions
Reinach soils: have a coarse-silty control section and are on higher positions

DRAINAGE AND PERMEABILITY:
Drainage: well drained
Permeability: moderately rapid
Runoff: negligible on 0 to 1 percent slopes and very low on 1 to 2 percent slopes
Flooding: rarely to frequently flooded for very brief to brief periods during April to October

USE AND VEGETATION: These soils are mainly cropped to alfalfa, peanuts, cotton, small grains, tame pasture, and grain sorghum. The native vegetation is tall and mid grasses with eastern cottonwood, pecan, tamarisk, and American elm.

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