ton yields from one-third to one bale, corn from 12 to 30 bushels, oats 

 from 20 to 50 bushels, and wheat from 10 to 15 bushels per acre. Cow- 

 peas do well. Potatoes, cabbage, and other vegetables and some fruits 

 do fairly well. Sorghum also gives fair yields. The cotton, corn, and 

 small grain are all fertilized, and the larger yields have been secured 

 wh«n liberal applications were given. Kainit is beneficial and is being 

 used more generally. The soil needs more humus and lime. Stable 

 manure should be applied wherever available. 



Some rust of cotton is reported, but it is not nearly as prevalent as on 

 the Iredell loam. Omitting deeper plowing on the deeper and more 

 sandy areas, this soil requires practically the same treatment and fer- 

 tilization as the Iredell loam. 



Land composed of Iredell fine sandy loam sells at $20 to $40 an acre.

IREDELL LOAM 



The Iredell loam, or typical "blackjack land," comprising an area of 

 14,592 acres, is a dark gray or dull or rusty brown loam or heavy, fine 

 sandy loam, having a depth of 4 to 8 inches. The subsoil is a brownish 

 yellow, impervious, waxy, sticky, clay extending to a depth of 20 to 36 

 inches where it passes into soft, disintegrated dark-green rock. This 

 clay, on exposure to weathering, turns a dull rusty brown color, as seen 

 in road cuts; cracks open upon drying, and when wet has the consist- 

 ency of putty. The soil contains from 5 to 25 per cent of small, rounded 

 It//
