70 FIELD CROPS FOR THE COTTON-BELT 



The yields of cotton are low on the Norfolk soils, rang- 

 ing from one-fourth to one-half bale to the acre. The 

 most urgent need of these soils is organic matter. In 

 addition, phosphatic and potassic fertilizers are often nec- 

 essary for best results. 



Tifton sandy loam. This type represents a rather 

 important cotton soil located in southern Georgia and 

 probably in the panhandle of Florida and in southern 

 Alabama. It is described as a "gray or yellowish-gray 

 medium sandy loam about 10 inches in depth." Drainage 

 is usually good and the yields of cotton are considerably 

 higher than on the associated Norfolk soils. 



The Orangeburg soils. In this series the surface soils 

 are gray or brownish in color. They are underlain 

 by a characteristic red sandy clay or stiff clay subsoil 

 which distinguishes them from the Norfolk soils. The 

 Orangeburg sandy loam and fine sandy loam are exten- 

 sively and successfully used for cotton, especially in cen- 

 tral South Carolina, the upper coastal plain of Georgia 

 and through the coastal plain of Alabama and Mississippi. 

 They also occur in east and northeast Texas. The Orange- 

 burg sand and fine sand are fairly important cotton soils in 

 these sections, being more productive than the correspond- 

 ing types of the Norfolk series, but not so extensive. 



As a rule the surface soils in this series are not retentive 

 of water, but the clay subsoils, in a measure, counteract 

 this defect. The most urgent needs of these soils are: 

 (1) organic matter, (2) deeper plowing, and (3) the preven- 

 tion of erosion. 



The Greenville series. The soils of this series are gen- 

 erally loamy, of reddish-brown to dark-red color, and are 

 underlain by a "red friable sandy clay subsoil." They 

 are admirably adapted to cotton, being more retentive of
