matter, and the supply of this woukl greatly increase the yields and 

 render the soil ninch more retentive of moisture. Bright tobacco is 

 especially well suited to this soil, and similar soils are used for the 

 production of this crop in Durham and other counties. Sweet pota- 

 toes, peanuts, watermelons, cantaloupes, and sorghum-cane give good 

 returns. The main crops grown are corn, cotton, and cowpeas, and 

 the yields of these are generally low except where the soil has been 

 heavily fertilized or manured.

DURHAM FINE SANDY LOAlf. 



This is one of the smallest types in the county and is confined to 

 small areas in the vicinity of Marvin and to a few isolated patches lying 

 to the soutli of Waxhaw. The soil is a light gray fine sandy loam 

 grading into a pale yellow fine sandy loam at about 4 to 6 inches and 

 extending to a depth of 8 to 20 inches. The subsoil is a yellow friable 

 fine sandy chiy or clay. The ty4De occupies the high ridges, being 

 gently rolling to rolling, and has excellent natural drainage. 



The crops and yields on this soil are quite similar to tliose on the 

 Durham sandy loam. This soil needs organic matter, and this can 

 best be supplied by turning under green manuring crops. Usually 

 frequent and shallow cultivation serves every purpose for this soil.
