SOILS OF THE EASTERN UNITED STATES AND THEIR USE-XXIII. 



THE ORANGEBURG FINE SANDY LOAM. 



GEOGRAPHICAL DISTRIBUTION. 



The Orangeburg fine sandy loam, in common with the other mem- 

 bers of the Orangeburg series, is found within the Atlantic and 

 Gulf Coastal Plains from southeastern North Carolina to west-cen- 

 tral Texas. By far the greater area of this soil occurs in two sepa- 

 rate belts in the east Gulf coast region and in one extensive region 

 west of the Mississippi River. The first of the eastern regions 

 marked by the widespread distribution of this type lies in northern 

 Florida, southern Georgia, southern Alabama, and adjacent por- 

 tions of Mississippi around Mobile Bay. Within this territory the 

 type is not one of the dominant soils, being exceeded in area by 

 members of the Norfolk and other series, although aggregating many 

 thousands of acres in extent. The second of the eastern belts extends 

 from south-central Georgia westward through central Alabama into 

 northeastern Mississippi. Within this region the Orangeburg fine 

 sandy loam and other members of the same series are widely distrib- 

 uted and in many of the soil survey areas constitute the dominant 

 soil types. 



West of the Mississippi River there is a large area within which 

 the Orangeburg fine sandy loarn and members of the series occupy 

 important rank in _ point of area and agricultural value. This 

 region comprises the northern and northwestern portion of Louisiana, 

 southwestern Arkansas, the extreme northeastern portion of Texas, 

 and a broad belt extending from the vicinity of Shreveport, La., 

 southwest to the vicinity of San Antonio, Tex. In this timbered 

 region, which separates extensive prairie areas, the members of the 

 Orangeburg series are important soils and the Orangeburg fine 

 sandy loam is the most important, both in extent and in agricultural 

 value. 



The Orangeburg fine sandy loam is preeminently a Gulf region 

 soil type with only scattered occurrences along the Atlantic coast. 

 It has been encountered in 50 different soil survey areas located in 

 10 States, and has been mapped to the extent of 2,507,840 acres. 

 Since only about one-seventh of the total area of the Coastal Plain
