WAYNETOWN SERIES

The Waynetown series consists of very deep, somewhat poorly drained soils that are deep or very deep to calcareous, stratified gravelly and sandy outwash. The Waynetown soils formed in loess or other silty material and in the underlying loamy and gravelly outwash. They are on outwash plains and stream terraces. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 1016 mm (40 inches), and mean annual air temperature is about 11 degrees C (51 degrees F).

COMPETING SERIES: These are the Aptakisic, Caseyville, Creal, Fitchville, Iva, Kendall, Starks, Stronghurst, and Yeddo series. Aptakisic soils are less than 127 cm (50 inches) to the base of the argillic horizon. Caseyville, Creal, Fitchville, Iva, Starks, Stronghurst, and Yeddo soils have less than 15 percent rock fragments in the lower part of the series control section. Kendall soils have less than 15 percent rock fragments in the lower part of the argillic horizon.

GEOGRAPHIC SETTING: Waynetown soils are on outwash plains and stream terraces. Slope ranges from 0 to 2 percent. The soils formed in 51 to 102 cm (20 to 40 inches) of loess or other silty material and in the underlying loamy and gravelly outwash. They are deep or very deep to calcareous, stratified gravelly and sandy outwash. Mean annual precipitation ranges from 940 to 1067 mm (37 to 42 inches). Mean annual air temperature ranges from 10 to 11 degrees C (50 to 52 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are Mahalasville and Rush soils. The poorly drained or very poorly drained Mahalasville soils are in depressions and have a mollic epipedon. When mapped in association with Waynetown soils, the Mahalasville soils have gravelly substrata. The well drained Rush soils are on higher lying positions on stream terraces and outwash plains.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. The depth to the top of an intermittent apparent high water table ranges from 15 to 61 cm (0.5 to 2.0 feet) during the winter and spring in normal years. The potential for surface runoff is very low or low. Saturated hydraulic conductivity is moderately high in the solum and very high in the underlying material. Permeability is moderate in the solum and very rapid in the underlying material.

USE AND VEGETATION: Most areas are cultivated. Corn, soybeans, wheat, and alfalfa-grass mixtures are the principal crops. Native vegetation is hardwood forest.

DISTRIBUTION AND EXTENT: West central Indiana and western Ohio; MLRA 111D. The series is of small extent.
