Stapp soils are deep to shale bedrock.
GEOGRAPHIC SETTING: Chickasawhay soils are on nearly level to undulating stream and marine terraces at low elevations in the Southern Coastal Plains. They formed in stratified loamy and clayey marine sediments. The climate is warm and humid with average annual temperature of 65 degrees F. and average annual precipitation of 55 inches near the type location. Slopes are dominantly 0 to 5 percent but range up to 8 percent.
GEOGRAPHICALLY ASSOCIATED SOILS: Besides the competing
Annemaine, these include the
Angie,
Cahaba,
Izagora,
Lenoir,
Harleston and
Chicora series. Angie soils have thick yellower subsoils and are on lower positions. The well drained Cahaba soils are on lower adjacent positions and have fine-loamy control sections. Izagora soils are on similar to lower positions, have fine-loamy control sections and have yellower subsoils. The somewhat poorly drained Lenoir soils are on lower adjacent positions and have yellower subsoils. Harleston soils are on similar positions and have coarse-loamy control sections. Chicora soils are on similar and have fine loamy control sections and have yellower subsoils.
DRAINAGE AND PERMEABILITY: Moderately well drained; medium or rapid runoff; slow permeability.
USE AND VEGETATION: Largely cleared and used for the commonly produced crops and pasture. Forested areas are in mixed hardwoods and pines.
DISTRIBUTION AND EXTENT: Southern Coastal Plains of Mississippi. The series is of minor extent.
