8 SOILS OF THE EASTERN UNITED STATES. 



and yard manures should be saved and applied to this type, or to 

 similar sandy soils upon the farm. Cottonseed meal, to the amount 

 of 500 pounds or more per acre, should be applied in conjunction with 

 the usual commercial fertilizers. Although the practice with regard 

 to the use of chemicals varies considerably in the different areas where 

 the type is found, in general those farmers securing the largest yields 

 of cotton from the Orangeburg fine sand are the ones who fertilize 

 heavily with a mixture which will analyze about 8 per cent of phos- 

 phoric acid, not less than 2 per cent of nitrogen, and from 6 to 10 

 per cent of potash. 



Very few commercial fertilizers ordinarily sold for cotton grow- 

 ing contain such a large amount of potash, and it is frequently neces- 

 sary for the progressive farmer to buy potash salts to be used in con- 

 junction with the more ordinary brands of cotton fertilizer. The 

 nitrogen should be supplied chiefly through the production of legumi- 

 nous crops, such as cowpeas, velvet beans, winter vetch, and crimson 

 clover. Where necessary, cottonseed meal may be used directly in 

 conjunction with the mineral fertilizers. In all instances care should 

 be taken to furnish adequate amounts of nitrogen and of potash in 

 the fertilization of this type. Smaller amounts of the mineral fer- 

 tilizers will ordinarily be required where the organic-matter content 

 of the surface soil is high, while satisfactory crops may only be se- 

 cured upon areas low in organic content through the abundant use 

 of the mineral fertilizers. 



LIMITATIONS UPON SPECIAL CROPS. 



The Orangeburg fine sand, where it is properly located with regard 

 to transportation facilities, is well suited to the production of quite 

 a variety of market-garden vegetables and small fruits. The cli- 

 matic surroundings and its inherent characteristics of texture, struc- 

 ture, and drainage render it suitable for medium to early truck crops 

 in practically all areas where it is found. In northeastern Texas and 

 in northern Louisiana the truck industry is rapidly being extended 

 upon this soil type. In the more eastern States only occasional 

 areas have been devoted to this form of farming. There is a con- 

 siderable opportunity for the extension of vegetable and fruit culture 

 upon this type. 



Like the Orangeburg sandy loam and the Orangeburg fine sandy 

 loam, this type is fairly well suited to the production of Cuban cigar- 

 filler tobacco. Owing to the considerable depth of sandy surface 

 soil, yields are frequently less than upon the other two types men- 

 tioned. Satisfactory crops, however, may be grown if attention is 

 paid to bringing the land into good condition before the crop is 

 planted, chiefly by the incorporation of organic matter in the surface 

 soil, coupled with careful tillage during the earlier part of the grow- 

 ing season.
