LOCATION WARNUT KSEstablished Series
The Warnut series consists of very deep, poorly drained, moderately permeable soils. They are formed in loamy alluvium. These soils occur in interdunal depressions on paleo-terraces of the Great Bend Sand Plains (MLRA 79). Mean annual air temperature is 56 degrees F (13 degrees C), and mean annual precipitation is 29 inches (74 centimeters). Slope ranges from 0 to 1 percent.

GEOGRAPHICALLY ASSOCIATED SOILS: These include the Carway, Dillhut, Funmar, Hayes, Pratt, Saltcreek, Solvay, and Turon series. The Carway soils have buried soil material that has 30-45 percent clay between 20 and 40 inches (50 and 102 centimeters). They are on similar positions. The moderately well drained, sandy Dillhut soils do not have an argillic horizon and are on low dunes. The well drained, coarse-loamy Hayes soils are on dunes. The well drained, sandy Pratt and Turon soils are on dunes. The well drained, fine-loamy Saltcreek soils are on dunes. Solvay soils are better drained and do not have a buried soil with 30 to 45 percent clay, and are on slightly higher positions.
DRAINAGE AND PERMEABILITY: Warnut soils are poorly drained. Runoff is very low and permeability is moderate. An apparent water table is present within 0 to 18 inches (0 to 46 centimeters) during April through June in most years.
USE AND VEGETATION: Mostly cultivated; winter wheat and grain sorghum are the principal crops.
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.
