COMPETING SERIES: These are the Conchovar, Irwin, Knifehill, Lubbock, Millpaw Nutreeah, and Ruidoso series.
Irwin soils have horizons with 40 percent or more clay within depths of 14 inches and have transitional horizons less than 3 inches thick between the A and Bt horizon.
Knifehill soils have redder hues.
Lubbock, Millpaw and Ruidoso soils are drier in the soil moisture control section during the month of July through September.
Lubbock soils have free carbonates within 32 inches.
Conchovar and Nutreeah have water table below 40 inches.

GEOGRAPHIC SETTING:
Landscape: upland
Landforms: foot slopes and fans below areas of soils formed in residuum from interbedded shale and limestone
Slopes: weakly concave or plane and commonly range from 2 to 7 percent but, range from 1 to 15 percent.
Parent material: clayey local alluvium or colluvium
Climate: subhumid
Mean annual precipitation: 61 to 86 centimeters (24 to 34 inches)
Mean annual temperature: 12 to 14 degrees C. (53 to 57 degrees F.)
Thornthwaite Annual P-E Index: 40 to 56

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Clime, Florence, Ivan, Kipson, Reading, and Sogn Soils.
Clime, Florence, Kipson, and Sogn soils are formed in residuum on steeper slopes adjacent to Tully soils.
Clime soils are moderately deep over shale.
Kipson soils is shallow over shale.
Sogn soils are shallow over limestone.
Florence soils are clayey-skeletal and are deep over limestone.
Ivan and Reading are fine-silty soils on flood plains below the Tully soils.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: well drained
Runoff: medium to very high.
Saturated hydraulic conductivity: low

USE AND VEGETATION: The larger, less sloping areas are mostly cultivated.
Wheat, sorghum, alfalfa, and corn are the principal crops.
The smaller and steeper areas are mostly used as rangeland.
Native vegetation is tall-grass prairie.

DISTRIBUTION AND EXTENT: Mostly in central to east-central Kansas in the Bluestem Hills. The series is extensive; about 300,000 acres.

MLRA OFFICE RESPONSIBLE: Salina, Kansas
