GRANVILLE GRAVELLY LOAM. 



The surface soil is a gray to yellowish-gray, fine sandy loam to a 

 depth of about 6 to 10 inches, with an estimated content of 25 to 50 per 

 ceut of small, angular quartz fragments and gravel. The subsoil is a 

 brownish to reddish plastic clay, extending to a depth of 36 inches, 

 mottled in the lower portions with yellowish-gray and red. Most of this 

 type is forested, the cultivated portion being devoted to the production 

 of corn, oats and cotton. This is a small and relatively unimportant 

 type. 



MECKLENBURG SERIES. 



The soils of this series have been mapped in rather large bodies in 

 Mecklenburg and Cabarrus counties, and will likely be encountered in 

 Rowan, Davidson, Guilford and other counties in the Piedmont Region. 

 These soils are closely associated with the Iredell soils and, in places 

 ai)pear, to represent Iredell material in an advanced stage of weathering. 

 They are derived from diorite, inica-diorite, metagabbro, and similar 

 rocks. The topography is undulating and gently rolling, and the sur- 

 face drainage good. The soils are productive, closely approximating 

 ill agricultural value the corresponding Cecil types. The members of 

 this series are locally known as the "red black-jack lands." 



MECKLENBURG CLAY LOAM. 



The surface soil of this type, locally known as "red black-jack land" 

 consists of 4 to 8 inches of brown to reddish-brown or dull red, heavy 

 loam or clay loam. The subsoil is a yellowish brown, ocher to red- 

 colored clay, extending to a depth of 24 to 30 inches, and having a 

 greasy feel, but at the same time, tenacious and sticky when wet, and 

 cracking open when drying. The soft feel is probably the result of 

 small mica scales present in the subsoil. The rotten rock usually comes 

 within 30 inches of the surface, although in places the heavy clay ex- 

 tends to a depth of 3 or 4 feet or more. This type also has a few 

 rounded iron pebbles or concretions on the surface. On eroded slopes 

 a red, heavy, clay loam or clay is exposed frequently. The clay loam is 

 naturally a very productive and desirable soil, and one which can be 

 built up to a high state of productiveness. It is especially adapted to 

 clovers, vetches, and soy beans, and is also good for cotton, corn, oats, 

 and wheat. Johnson grass is indigenous, and this together with Japan 

 clover, furnishes excellent pasturage.
