Tallapoosa soil series

A representative soil profile of the Tallapoosa series. Tallapoosa soils formed in residuum weathered from phyllite. These somewhat excessively drained soils have soft bedrock at shallow depths and are droughty during dry periods. (Soil Survey of Coosa County, Alabama; by John L. Burns, Natural Resources Conservation Service)

 

The Tallapoosa series consists of shallow, well drained, moderately permeable soils that formed in residuum weathered from phyllite and mica schist. These soils are on narrow ridges and sideslopes of the Piedmont Plateau. Slopes range from 5 to 80 percent.

 

TAXONOMIC CLASS: Loamy, mixed, semiactive, thermic, shallow Typic Hapludults

 

Solum thickness ranges from 3 to 20 inches. Depth to a paralithic contact (Cr) is 10 to 20 inches and depth to hard bedrock (R) is more than 6 feet. Content of rock fragments ranges from 0 to 35 percent by volume in the solum. Reaction is very strongly acid or strongly acid throughout.

 

USE AND VEGETATION: Most of the soil is in forest of mixed hardwood and pine. A small percentage is cleared and used for growing corn, small grain, and pasture.

 

DISTRIBUTION AND EXTENT: Piedmont Plateau of Alabama, Georgia, North Carolina, South Carolina, and possibly Virginia. The series is extensive. Tallapoosa soils have been included in the Madison and Louisa series. This revision changes mineralogy from micaceous to mixed based on regional observations in Alabama and Georgia. Also, the 8th edition of the Keys to Soil Taxonomy removed shallow families from the Inceptic (formerly Ochreptic) subgroups.
