Gwinnett soil series

A representative soil profile of the Gwinnett soil series. (Soil Survey of Jasper County, Georgia; by James R. Latham, Natural Resources Conservation Service)

 

The Gwinnett series consists of deep, well drained, moderately permeable soils that formed in intermingled basic crystalline materials of the Piedmont. Slopes range from 2 to 60 percent. Near the type location, the average annual precipitation is about 49 inches and average annual air temperature is about 61 degrees F.

 

TAXONOMIC CLASS: Fine, kaolinitic, thermic Rhodic Kanhapludults

 

Solum thickness ranges from 20 to 60 inches. Depth to soft bedrock ranges from 40 to 60 inches and depth to hard bedrock ranges from 5 to more than 10 feet. The soil in all horizons ranges from very strongly acid through slightly acid except where the surface has been limed. Small dark accumulations and concretions range from 0 to 5 percent in the solum. Rock fragments, mainly pebbles and some cobbles, are 0 to 20 percent in the A horizon, and 0 to 15 percent in the B horizon and C horizon.

 

USE AND VEGETATION: Much of the soil was cleared and used for growing cultivated crops, hay, and pasture. Most of the acreage has reverted to forests, chiefly of loblolly and shortleaf pine. The original forest cover type is oak-pine and Virginia pine.

 

DISTRIBUTION AND EXTENT: Piedmont areas of Alabama, Georgia, North Carolina, South Carolina, and Virginia. The series is of moderate extent.
