LOCATION PLEV KSEstablished Series
The Plev series consists of very deep, poorly drained, rapid over moderately permeable soils that formed in sandy eolian deposits over a buried alluvial soil. These soils are in interdunal depressions on paleo-terraces in river valleys of the Great Bend Sand Plains (MLRA 79). Mean annual temperature is 56 degrees F (13 degrees C), and mean annual precipitation is 29 inches (74 centimeters). Slope is concave and ranges from 0 to 1 percent.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dillhut , Dillwyn, Solvay , and Tivin soils. Dillhut soils are better drained. Dillwyn soils do not have a buried soil. The somewhat excessively drained Tivin soils do not have a buried soil or lamellae within 80 inches (203 centimeters). Tivin soils are on dunes. Solvay soils are somewhat poorly drained, are fine-loamy and occur in interdunes.
DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is very low or low. Permeability is rapid over moderate. A perched water table is present with an upper limit of 4 to 12 inches (10 to 30 centimeters) and a lower limit of 35 to 46 inches (89 to 117 centimeters), and an apparent water table with an upper limit of 75 to 82 inches (190 to 208 centimeters) from February thru May in most years
USE AND VEGETATION: Most areas are in native range. Native vegetation is dominated by sand bluestem, indiangrass, and little bluestem.
DISTRIBUTION AND EXTENT: South Central Kansas. LRR H Great Plains Winter Wheat and Range, MLRA 79 Great Bend Sand Plains. The series is of small extent.
