BUCKATUNNA SERIES
The Buckatunna series consists of very deep, moderately well drained, moderately slowly permeable soils on low stream terraces in the Southern Coastal Plains Major Land Resource Area. They formed in clayey fluvial sediments. Near the type location, the average annual precipitation ranges from 55 to 65 inches and the mean annual temperature is 67 degrees F. Slopes are dominantly 0 to 5 percent but range up to 8 percent.

GEOGRAPHIC SETTING: Buckatunna soils are on nearly level to undulating low stream terraces in the Southern Coastal Plain. They formed in stratified clayey fluvial 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.

Annemaine soils, these include the
Bassfield,
Bigbee,
Cahaba,
Harleston,
Jena,
Latonia,
Mantachie,
Mooreville,
Una, and
Urbo series. The well drained Bassfield and Cahaba soils are on higher terrace positions. The excessively drained Bigbee soils are sandy in the particle size control section and are on natural lower levee positions. The coarse-loamy Jena soils are in slightly higher positions on natural levees. The somewhat poorly drained Mantachie soils are in slightly lower, less convex positions. The moderately well drained Mooreville soils have fine-loamy particle size control sections. The poorly drained Una and the somewhat poorly drained Urbo soils are on lower adjacent positions.
DRAINAGE AND PERMEABILITY: Moderately well drained; slow to medium runoff; slowly permeable. Buckatunna soils are subject to occasional to rare flooding for brief duration in winter and early spring.
USE AND VEGETATION: Most areas of Buckatunna soils are used for timber production and wildlife habitat. The dominant vegetation consists of mixed hardwoods and pines. When cultivated, corn, small grains, soybeans, and truck crops are the dominant crops.
DISTRIBUTION AND EXTENT: Southern Coastal Plain of southeast Mississippi. The series is of moderate known extent.
