LOCATION TIVIN              KS 

TIVIN SERIES

The Tivin series consists of very deep, somewhat excessively drained, rapidly permeable soils that formed in sandy eolian sediments. These soils are on dunes on paleo-terraces in river valleys of the Great Bend Sand Plains (MLRA 79). Slopes range from 1 to 35 percent. Mean annual precipitation is 26 inches (66 centimeters) and mean annual temperature is 56 degrees F (13 degrees C).

TAXONOMIC CLASS: Mixed, mesic Typic Ustipsamments

Some pedons have a 2C or 2Ab horizon within 40 to 60 inches (102 to 152 centimeters) with textures of very fine sandy loam, loam, fine sandy loam or silt loam. Clay ranges from 10 to 20 percent. Some pedons also have a 3C horizon with sand, fine sand, or coarse sand textures. Clay ranges from 0 to 3 percent. Some pedons contain carbonates and gravels.

COMPETING SERIES: These are the Duda (SD), McKelvie (NE), Peji (SD), Royosa (NM), Simeon (NE), Tonalea (AZ) and Valentine (NE) soils in the same family. All of these series have a lower mean annual temperature and less mean annual precipitation.

GEOGRAPHIC SETTING: Tivin soils

Parent material: sandy eolian sediments
Landform: dunes on paleo-terraces
Slopes: 1 to 35 percent
Elevation: 1522 to 1770 feet (463.9 to 539.5 meters)
Mean annual air temperature: 55 to 57 degrees F (13 to 14 degrees C).
Mean annual precipitation: 24 to 35 inches (61 to 89 degrees C)
Wettest months: Mar. - Oct.
Driest months: Nov. - Feb.
Frost-free period: 187 to 225 days

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dillhut, Langdon, Plev, Pratt, Solvay, Spelvin, and Turon series. The moderately well drained, sandy over loamy Dillhut soils have a buried soil between 20 and 40 inches (50 to 102 centimeters). They occur on lower landscape positions. The somewhat excessively drained, sandy Langdon soils contain lamellae, and are on similar positions. The poorly drained, sandy Plev soils have a buried soil between 40 and 70 inches (102 to 178 centimeters), and are in interdunal depressions. The well drained, sandy Pratt and Turon soils have an argillic horizon and contain lamellae. They occur on lower relief dunes. The somewhat poorly drained, fine-loamy Solvay soils occur in interdunes. The well drained, fine-loamy Spelvin soils occur on interdunes.

DRAINAGE AND PERMEABILITY: Tivin soils are somewhat excessively drained. Runoff is low and permeability is rapid. A loamy substratum phase is recognized for this soil.

USE AND VEGETATION: Used mainly for grazing beef cattle. Native vegetation is sand bluestem, sand dropseed, and prairie sandreed.

DISTRIBUTION AND EXTENT: South Central Kansas. LRR H Great Plains Winter Wheat and Range, MLRA 79 Great Bend Sand Plains. This series is of moderate extent.

MLRA OFFICE RESPONSIBLE: Salina, Kansas
