RANGE IN CHARACTERISTICS:
Thickness of solum: 102 to more than 152 centimeters (40 to more than 60 inches)
Where the A, E, and upper B horizons are mixed and have moist chroma and value of less than 3.5 the combined thickness is less than 10 inches, or they have less than 1 percent organic matter, or they have less than 50 percent base saturation in some part of the Bt horizon.
A horizon:
Hue: 10YR
Value: 3 or 4
Chroma: 1 or 2
E horizon:
Hue: 10YR
Value: 4 or 5
Chroma: 1 or 2
Texture: loam or silt loam
In some pedons few or common redoximorphic iron concentration masses: higher chroma
Combined thickness of the A and E horizon: less than 41 centimeters (16 inches)
Reaction: slightly acid to strongly acid
Bt horizon:
Hue: 10YR or 2.5Y
Value: 3 to 5
Chroma: 1 or 2
Redoximorphic iron depletion masses: shades of gray
Redoximorphic iron concentration masses: shades of brown or red
Texture: clay loam, silty clay loam, silty clay, or clay
Clay content: 35 and 60 percent
Reaction: slightly alkaline to strongly acid
BC and C horizons:
Hue: 10YR or 2.5Y
Value: 3 to 5
Chroma: 1 or 2
Redoximorphic iron depletion masses: shades of gray
Redoximorphic iron concentration masses: shades of brown or red
Texture: clay loam, silty clay loam, silty clay, or clay

COMPETING SERIES: This is the
Taloka series.
Taloka soils have a combined A horizon and E horizon 16 to 40 inches thick.
GEOGRAPHIC SETTING:
Landforms: uplands
Slope: 0 to 3 percent
Parent material: fine or moderately fine textured material from old alluvium or weakly fissile clayey shale and possibly a thin loess mantle
Climate: moist, humid
Average annual precipitation: 97 to 114 centimeters (38 to 45 inches)
Thornthwaite P-E index: 62 to 84
Mean annual temperature: 14 to 18 degrees C. (57 to 65 degrees F.)
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Barden,
Dennis and
Okemah series.
Barden soils lack an E horizon and have a BA horizon and are in similar positions on the landscape.
Dennis and Okemah soils are on higher parts of the landscape.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage; somewhat poorly drained
Runoff: high to very high
Saturated hydraulic conductivity: low
Perched water table: 15 to 46 centimeters (0.5 to 1.5 feet) from December through April due to episaturation.
USE AND VEGETATION: Mainly cultivated to cropland.
Principal crops are small grains, sorghums, and soybeans.
A smaller amount is in tame pasture, native range, and hayland.
The native vegetation is tall grass prairie.
DISTRIBUTION AND EXTENT: Northwestern Arkansas, southeastern Kansas, southwestern Missouri, and eastern Oklahoma. The series is extensive
MLRA OFFICE RESPONSIBLE: Salina, Kansas
SERIES ESTABLISHED: Labette County, Kansas; 1926.
