CARWAY SERIES

The Carway series consists of very deep, somewhat poorly drained, moderate over very slowly permeable soils. They are formed in loamy eolian sediments over a buried alluvial soil. These soils occur in interdunal depressions on paleo-terraces in river valleys 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.

The Carbika soils have a mollic epipedon and are fine textured. They are on similar positions. The moderately well drained, sandy Dillhut soils do not have an argillic horizon and are on low dunes. Funmar and Taver soils are moderately well drained and are on higher positions surrounding the depressions. 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: somewhat poorly.
Runoff: very low
Permeability: moderate over very slow.
Episaturation: A perched water table is present with an upper limit of 0 to 24 inches (0 to 61 centimeters) and a lower limit of 37 to 49 inches (94 to 124 centimeters) during December through June in most years.
