PIKD.MO.M PLATEAU SOILS. 



The soils of the Piedmont Plateau are derived almost exclusively 

 from the disintegration of igneous or inetamorphic rocks, the 

 materials of which have been further modified by local erosion 

 and stream action. The characteristic soil of the region is the Cecil 

 chiy, a heavy but frial)le red clay, extending from New Jersey to 

 Georgia and forming the soil or the subsoil over much of the area
