Blanton soil and landscape

A soil profile of Blanton sand. (Soil Survey of Screven County, Georgia; by Gary C. Hankins, Jr., Natural Resources Conservation Service)

 

Landscape: Corn growing in an area of Blanton sand, 0 to 5 percent slopes. With proper management, such as irrigation, this soil can be productive for certain crops.

 

The Blanton series consists of very deep, somewhat excessively drained to moderately well drained, moderately to slowly permeable soils on uplands and stream terraces in the Coastal Plain. They formed in sandy and loamy marine or eolian deposits. Near the type location, the mean annual temperature is about 67 degrees F., and the mean annual precipitation is about 55 inches. Slopes range from 0 to 45 percent.

 

TAXONOMIC CLASS: Loamy, siliceous, semiactive, thermic Grossarenic Paleudults

 

Solum thickness ranges from 60 to more than 80 inches. Content of gravel-sized fragments, dominantly quartz and ironstone pebbles, is less than 10 percent, by volume, in all horizons except the A and E horizons which may have as much as 35 percent, by volume. Reaction ranges from very strongly acid to moderately acid throughout except where the surface has been limed. Depth to the Bt horizon is commonly 50 to 70 inches but ranges from 40 to 80 inches. Redoximorphic features that indicate wetness occur at depths of between 30 and 72 inches.

 

USE AND VEGETATION: Many areas are cleared and used for cropland, truck crops, improved pasture, and hayland. Natural vegetation consists of slash and longleaf pine, red, bluejack, and live oak with an understory of chinkapin, highland fern, huckleberry, and pineland threeawn, bluestem, panicum, and tickclover.

 

DISTRIBUTION AND EXTENT: Coastal Plain of Alabama, Florida, Georgia, North Carolina and South Carolina. The series is of large extent, over 1 million acres.
