Tifton soil surface (Apc horizon) and subsoil (Btv horizon)
The Tifton series was one of the first series to be recognized in Georgia. It was established in Grady County, Georgia, in a 1908 soil survey conducted by Hugh Hammond Bennett.
Tifton soils occur throughout the Southern Coastal Plain in the Southeastern U.S. They are the most extensive soils in Georgia. They occur on more than 2 million acres in the State. They have been correlated in more Georgia counties (56) than any other soil. Tifton soils formed in loamy sediments of marine origin. They are among the most important agricultural soils in the State. About 27 percent of Georgia’s prime farmland is in areas of Tifton soils. Cotton, peanuts, soybeans, and corn are the principal crops grown on these soils.
The Tifton series consists of very deep, well drained soils that formed in loamy marine sediments. Tifton soils are on interfluves. Slopes range from 0 to 8 percent. Mean annual temperature is about 18 degrees C (64 degrees F), and the mean annual precipitation is about 1360 millimeters (53 inches).
TAXONOMIC CLASS: Fine-loamy, kaolinitic, thermic Plinthic Kandiudults
Plinthite: Depth to horizons with 5 percent or more plinthite is dominantly 76 to 127 centimeters (30 to 50 inches), but in some pedons it is 63 centimeters (25 inches).
Depth to Redox features: Predominantly greater than 102 centimeters (40 inches), but some pedons have iron depletions below a depth of 76 centimeters (30 inches).
Ac or Apc horizons:
Hue: 10YR or 2.5Y; Value: 3 to 5; Chroma: 1 to 4
Texture: sand, fine sand, loamy fine sand, loamy sand, loamy coarse sand, sandy loam, fine sandy loam, or their gravelly analogues
Fragments: nodules of ironstone range from 5 to 25 percent, by volume
Btv horizon (upper part):
Hue: 7.5YR or 10YR; Value: 5 or 6; Chroma: 4 to 8
Texture: Texture is dominantly sandy clay loam but can range up to sandy clay or their gravelly analogues.
Fragments: nodules of ironstone range from 0 to 15 percent, by volume. Nodular plinthite ranges from 5 to 30 percent.
Redox features: Masses of oxidized iron in shades of red and brown range from few to many. Some pedons have iron depletions below a depth of 76 centimeters (30 inches).
USE AND VEGETATION:
Most areas of Tifton soils are under cultivation with cotton, corn, peanuts, vegetable crops, and small grains. Some areas are in pasture and forestland. The forested areas consist largely of longleaf pine, loblolly pine, slash pine with some scattered hardwoods on cutover areas.
DISTRIBUTION AND EXTENT:
Major Land Resource Area (MLRA): The series occurs primarily in the Southern Coastal Plain (MLRA 133A), but it also occurs to a lesser extent in the Atlantic Coast Flatwoods (MLRA 153A). Extent: large extent.
