MECKLENBURG SANDY LOAM. 



The surface soil of tliis type consists of 6 to 12 inches of dark-brown 

 to reddish -brown sandy loam to light loam. The subsoil to a depth of 

 20 to 30 inches is a brownish-yellow or ocherous-yellow, sticky, imper- 

 vious clay. Usually below this depth the rotten rock is encountered, 

 but occasionally the clay subsoil extends to a depth of 3 feet or more. 

 On some areas a few small mica scales occur in the subsoil. Iron peb- 

 bles are found on the surface throughout the type in many localities. 

 This type is better suited to cotton than the other members of the series. 

 Corn, oats, soy beans, and cowpeas are successfully grown. This soil is 

 easy to till, and warms up and dries out earlier in the spring than the 

 loam or clay loam.

MECKLENBUKG LOAM. 



The surface soil of the Mecklenburg loam, to a depth of 6 to 8 inches, 

 is a loam to a heavy sandy loam, varying in color from dark-brown to 

 Teddi.=h-brown. The subsoil is a yellowish-brown or ocher-colored, 

 tenacious clay, extending to a depth of 36 inches. Usually at 24 to 30 

 inches the subsoil becomes more friable, owing to the presence of partly 

 decomposed rock, and occasionally the bed rock is reached within the 

 3-foot section. Small, rounded, iron pebbles or concretions are present 

 in the soil in many localities, while small scales of mica are character- 

 istic of the subsoil, giving it a greasy, soft, feel. 



This soil is well suited to corn, oats, cotton, and wheat, and is ad- 

 mirably adapted for pasture. Japan clover, Johnson grass, and other 

 grasses are indigenous, where permitted to grow. Cotton matures 

 a few days earlier on it than upon the clay loam. Cotton has a ten- 

 dency to rust, and com to "french" on all types of this series. Kainit 

 is used to minimize the injury caused by these diseases.
