ANGIE SERIES

The Angie series consists of very deep, moderately well drained, slowly permeable soils that formed in loamy and clayey sediment on Tertiary-aged uplands. These soils are on broad, level to strongly sloping coastal plains. Slope is dominantly 1 to 5 percent, but the range is 0 to 12 percent. Mean annual precipitation is about 1473 mm (58 in) and mean annual temperature is about 18.9 degrees C (66 degrees F)

TAXONOMIC CLASS: Fine, mixed, semiactive, thermic Aquic Paleudults

Shubuta soils do not have aquic conditions within 30 inches of the soil surface.
Susquehanna soils are somewhat poorly drained and higher shrink-swell potential.
Vadian and Wilcox soils have smectitic mineralogy and intersecting slickensides within 40 inches of the soil surface.

DRAINAGE AND PERMEABILITY: Moderately well drained; slow permeability. Runoff is medium to rapid. A water table is at a depth of 2 to 5 feet during winter and early spring.

USE AND VEGETATION: Almost all areas of Angie soils are in forest of mixed hardwood and pine. A small amount is used for pasture.

DISTRIBUTION AND EXTENT:
Distribution: Coastal Plain of Alabama, Arkansas, Georgia, Louisiana, Mississippi, South Carolina, Virginia, and possibly Oklahoma and Texas.
Extent:Large
