IREDELL FINE SANDY LOAM. 



The surface soil of this type consists of a gray to grayish-brown, 

 fine to medium sandy loam, varying in depth from 5 to 10 inches. The 

 subsoil is a yellow to brownish, impervious waxy, sticky clay, being very 

 plastic when wet, and cracking open when dry. The subsoil seldom 

 extends below 24 or 30 inches, grading at this depth into the rotten rock. 

 Small, rounded, iron pebbles or concretions, and occasionally bowlders 

 are scattered over the surface. This type includes spots of Durham 

 B.ne sandy loam and Cecil fine sandy loam. This type has been mapped 

 in' Granville, Cabarrus, and Mecklenburg counties. The soil is used 

 maiul.y for corn, oats, cotton, and the lighter areas for tobacco, sweet 

 potatoes, sorghum, garden vegetables, but is best suited to small grains 

 and pasturage.

IREDELL LOAM. 



The surface soil consists of a dark gray, to a dull brown loam, silty 

 loam, or fine sandy loam, with a depth of 4 to 8 inches. The subsoil is 

 a vellowish to brown, generally yellowish-brown or greenish-brown, 

 waxy, sticky cla.v, extending to a depth of 20 to 36 inches. Frequently 

 at 24 to 30 inclies it grades into a soft, rotten rock. Subsoil, on ex- 

 posure to weathering, changes to a dull brown. Small, rounded, iron 

 concretions over a large part of this type are mapped in Cabarrus, 

 Granville, Mecklenburg, Randolph and Richmond counties. Until re- 

 ceiitlv the Iredell loam was considered as a poor soil for general farm- 

 ing, but now it is highly prized. It is well adapted to com, oats, wheat, 

 and grasses. Oats seem to do better than any other crop. Cowpeas, 

 Johnson grass, and lespedeza do well. Grasses make an excellent
