Dewey soil and landscape

Soil profile: A typical profile of a Dewey soil. The Dewey soils, which are very deep and well drained, have few limitations. (Soil Survey of McMinn County, Tennessee; by Richard L. Livingston and Melissa C. Oliver, Natural Resources Conservation Service)

 

Landscape: The corn and grass strips in the background are in an area of Dewey clay loam, 5 to 12 percent slopes, eroded.

 

The Dewey series consists of very deep, well drained, moderately permeable soils on uplands. These soils formed in residuum of limestone or in 1 to 2 feet of old alluvium and the underlying residuum from limestone. Slopes range from 2 to 40 percent.

 

TAXONOMIC CLASS: Fine, kaolinitic, thermic Typic Paleudults

 

Thickness of the solum and depth to limestone bedrock are more than 60 inches. The soil is strongly acid or very strongly acid unless limed. Rock fragments are mostly gravel size chert and range from 0 to 15 percent in each horizon. Some horizons range up to 25 percent below 40 inches.

 

USE AND VEGETATION: Most areas are cleared and used for row crops, small grain, hay, pasture. The native vegetation is mixed hardwoods.

 

DISTRIBUTION AND EXTENT: Southern Appalachian Ridges (MLRA 128) and Valleys and the Highland Rim and Pennyroyal (MLRA 122) in Tennessee, northwest Georgia, and northern Alabama. The series is of large extent.
