CECIL CLAY. 



The Cecil Clay is the red heavy clay land of the Piedmont Plateau. 

 The surface soil for 4 to 6 inches is either a red clay or heavy clay loam, 

 underlain to a depth of several feet by a red, stiff, tough clay. In a few 

 localities the first 2 or 3 inches of the surface may be a heavy loam, 

 while in other places the stiff raw clay has been left exposed by erosion. 

 The Cecil clay is inherently a strong and productive soil, but it requires 

 careful handling and the use of strong teams and machinery to properly 

 prepare it in order for it to produce its best yields. This soil is par- 

 ticularly adapted to the production of wheat, oats, red clover, orchard 

 grasses, and is one of the best soils in the State for these crops. It is 

 also used for the growing of cotton and corn, but the bolls do not open as 

 well as upon the sandy loam.

CECIL CL-'LY LOAM. 



The Cecil Clay Loam, or commonly called "red land," is one of the 

 largest and most important types, and will likely occur in every county 

 in the Piedmont region of North Carolina. It really represents an 

 intermediate grade of material between the Cecil clay and the sandy
