MORRISVILLE SERIES

The Morrisville series consists of deep, moderately well drained soils formed in loamy till and the underlying residuum from interbedded limestone and clayey shale. These soils are on till plains. Slope ranges from 12 to 25 percent. Mean annual precipitation is about 1016 mm (40 inches), and mean annual air temperature is about 12 degrees C (54 degrees F).

TAXONOMIC CLASS: Fine, mixed, active, mesic Oxyaquic Hapludalfs

COMPETING SERIES: These are Aaron, Alsup, Brookside, Derinda, Ebal, Goodson, Miamian, Shircliff, Skrainka, Useful, and Vincent series. Aaron, Alsup, Ebal, Goodson, and Useful soils do not have igneous pebbles in the upper part of the series control section. Brookside, Miamian, Shircliff, Skrainka, and Vincent soils do not have a lithic contact within a depth of 152 cm (60 inches). Derinda soils have a paralithic contact within a depth of 102 cm (40 inches).

GEOGRAPHIC SETTING: Morrisville soils are on shoulder slopes and back slopes on hills and valley sides on till plains of Illinoian age. Slope ranges from 12 to 25 percent. The soils formed in loamy till and the underlying residuum from interbedded limestone and clayey shale. Mean annual precipitation ranges from 889 to 1143 mm (35 to 45 inches). Mean annual air temperature ranges from 11 to 14 degrees C (51 to 57 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Hickory, Jonesboro, Loudon Nicely, Schaffer, and Westboro series. The well drained Hickory soils are on associated landscape positions. The Loudon, Jonesboro, and Nicely are on summits. The Schaffer and Westboro soils are somewhat poorly drained and are on broad summits.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. The depth to the top of an intermittent perched high water table ranges from 61 to 107 cm (2.0 to 3.5 feet) between December and April in normal years. The potential for runoff is high or very high. Saturated hydraulic conductivity is moderately high or moderately low. Permeability is moderately slow or slow.

USE AND VEGETATION: Most areas are pastured or in woodland. Some areas are cultivated. Hay and corn are the principal crops.

DISTRIBUTION AND EXTENT: Southwestern Ohio; MLRA 114A. The series is of small extent.
