326 MISCELLANEOUS FARM SUBJECTS 



The difference in the origin, drainage, color, and organic- mat- 

 ter content has given rise to several series of alluvial soils in the 

 humid portion of the United States. 



Congaree Series. Brown or reddish-brown soils found along 

 Piedmont streams and representing wash from Cecil soils. Valuable 

 and dependable corn soils, but too low and moist for cotton. 



Huntington Series. Dark-brown to yellowish-brown soils oc- 

 curring along streams in the Allegheny plateaus. Both the general 

 farm crops and truck crops thrive on these soils. 



Miller Series. Soils of the Miller series are among the most 

 productive alluvial soils of the United States. The Miller fine sand 

 gives moderate yields of cotton and corn, and higher lying areas seem 

 adapted to fruit, especially peaches. Vegetables also do well. The 

 fine sandy loam, a more extensive member of the series, gives better 

 yields of cotton and corn, and is also well adapted to truck and fruit, 

 peaches, plums, and pears being grown to considerable extent in parts 

 of Texas. It is also an excellent soil for alfalfa, the acreage of which 

 has been rapidly extended in recent years. Vegetables may be grown 

 with profit, and in some cases irrigation is practiced, the water being 

 secured from artesian wells. The silt loam has about the same ex- 

 tent as the fine sand. It is used for about the same crops as the fine 

 sandy loam and clay, i. e., cotton, corn, sugar cane, and alfalfa. The 

 clay is the most extensive and strongest soil of the series. Surpassed 

 by few soils in the production of cotton and alfalfa, it is no less 

 valuable in the growing of sugar cane. The Miller soils from their 

 origin and the relatively circumscribed area of the formation from 

 which they are derived are not an extensive series. 



Ocklocknee Series. This is gray to yellowish-brown soils found 

 along streams, in Coastal Plain Alabama, Georgia and Mississippi. 

 Cotton, corn and pasturage are the leading products. 



W 'abash Series. This comprises the most important of the allu- 

 vial types of soil. It embraces those soils having a dark-brown tP 

 black color and a large percentage of organic matter. These soils 

 are typical of the Mississippi River, but there is no sharp distinction 

 between them and other bottom soils found along the rivers of the 

 Middle West. The Wabash soils are among the strongest and most 

 productive types of the country. 



The most extensive type of the series is the silt loam, by far the 

 greater part of which is found north of the southern tier of States, 

 and therefore cotton is not so important a crop as corn, grass, and 

 small grains, of which fair to large yields are secured, depending 

 upon the condition of drainage. The next soil in point of area is the 

 Wabash clay. In the Southern States this is considered the best cot- 

 ton soil, producing on the average over a bale of lint to the acre. 

 Farther north it gives large yields of corn. A small area of the heavy 

 clay has been found in Texas, where it gives heavy yields of cotton, 

 corn, oats, and forage crops. The Wabash loam is the third soil in 

 area; occurring to the north of the cotton sections it is used chiefly for 

 corn, to which it is well adapted. It can be used to advantage in the 

 production of canning crops, such as sugar corn, tomatoes, green
