A tale of two soils in Warren County, MS James Lindsay SWS5716C-Pedology Spring 2012

Soils are located in the Memphis- Natchez-Adler association: Well Drained and moderately well drained soils of hilly loessal uplands and local silty alluvium

Mississippi State soil is the Natchez Silt Loam Occurs in ~.6% of state Inseptisols ▫Ochric Epipedon ▫Cambric horizon
