Warnock soil series

A representative soil profile of the Warnock series. (Soil Survey of Union County, Arkansas; by Leodis Williams, Natural Resources Conservation Service)

 

The Warnock series consists of very deep, moderately well drained, moderately permeable soils that formed in loamy marine sediments. These soils are on uplands of the Western Coastal Plain. Slopes range from 1 to 8 percent. Mean annual temperature is about 65 degrees F. and mean annual precipitation is about 50 inches.

 

TAXONOMIC CLASS: Fine-loamy, siliceous, semiactive, thermic Typic Paleudults

 

Solum thickness exceeds 60 inches. Soil reaction ranges from strongly acid to extremely acid throughout, except for surfaces layers that have been limed. Fine rounded quartz pebbles range from one to about 10 percent by volume in all horizons. Base saturation at 50 inches below the top of the Bt horizon ranges from 10 to 30 percent.

 

USE AND VEGETATION: Most areas of Warnock soils are used for woodland; mainly, loblolly and shortleaf pine. Cleared areas are used mostly for bermudagrass and bahiagrass pasture. Some cleared areas are used for soybeans and cotton.

 

DISTRIBUTION AND EXTENT: Western Coastal Plain of Arkansas, Louisiana and Texas, and possibly the Southern Coastal Plain of Alabama and Mississippi. The series is of large extent. These soils were formerly included in the Norfolk series.
