TAVER SERIES

The Taver series consists of very deep, moderately well drained, very slowly permeable soils that formed in alluvium. These soils are on paleo-terraces in river valleys of the Great Bend Sand Plains (MLRA 79). Slope ranges from 0 to 1 percent. Mean annual precipitation is 29 inches (74 centimeters) and the mean annual temperature is 56 degrees F (13 degrees C).

COMPETING SERIES: These are the Blazefork (KS) and Ladysmith (KS) soils. These soils do not have sandy surfaces and also the sandier buried soil material is deeper.

Slopes: 0 to 1 percent
Elevation: 1474 to 1796 feet (449.3 to 547.4 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 centimeters)
Wettest months: Mar. - Oct.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Carbika, Farnum, Funmar , Naron, and Saltcreek series. Carbika soils are in depressions and are poorly drained. Farnum, Funmar, Naron and Saltcreek soils are fine-loamy and located on dunes. Funmar and Saltcreek soils have a buried soil below 20 inches (50 centimeters).

DRAINAGE AND PERMEABILITY: Taver soils are moderately well drained. Runoff is slow and permeability is very slow.

USE AND VEGETATION: Most of these soils are used for small grains and sorghums. Native vegetation was little bluestem, big bluestem, indiangrass, and switchgrass.

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