lEEDELL LOAM 



The Iredell loam, generally known as "blackjack oak land" or "pipe- 

 clay land," covers 22,528 acres. It and tlie fine sandy loam are dis- 

 tinguislied from other soils by the putty-like character of the subsoils 

 and the dominant blackjack oak growth. 



The surface soil is dark gray to brown loam or heavy fine sandy loam, 

 carrying a considerable quantity of small rounded iron concretions and 

 extending to a depth of about 6 inches. Fragments of quartz and 

 nigger-head rock are present on surface in a few localities. The subsoil 

 is a brownish-yellow to light brown sticky impervious heavy clay to a 

 depth of 24 to 30 inches, where it usually passes into the soft rotten 

 rock. 



The largest areas occur to the south of Harrisburg, north by Car- 

 rikers Store, to the southeast of Concord around Faggarts, and to the 

 north of Mount Olive Church. Most of it has a fairly level surface. 

 This fact, together with the dense nature of the subsoil, results in poor 

 drainage over the flatter and more depressed areas. Open ditches serve 

 well. 



Most of the Iredell loam is fairly easy to cultivate. The difficulty 

 comes in turning up much of the clay subsoil at any one time. Fall 

 plowing, however, is good for this land, as the heavy clay crumbles 

 down during the winter. The soil is well suited to the growing of 

 wheat and oats, although corn and cotton do well when the soil has 

 been limed and kainit added to correct the frenching of corn and the 

 rusting of cotton. This is a good productive soil and one which is com- 

 ing to be so recognized.

 subsoil of Iredell loam:
