SOILS 



23 



Nebraska, 24,640 acres. These soils are highly valued for 

 the production of celery, onions, peppermint and cab- 

 bage. 



47. Piedmont plateau. — This area lies between the At- 

 lantic Coastal Plain and the Appalachian mountains and 

 extends from the Hudson river to east-central Alabama. 

 The land is gently rolling to hilly. The sand (259,744 

 acres in Georgia, North Carolina, South Carolina and 

 Virginia) "is especially adapted to sweet potatoes and 

 watermelons." 



48. Appalachian mountains and plateau. — The loams, 

 gravelly loam, sandy loam, and fine sandy loam of the 

 DeKalb series are well adapted to vegetables. There are 

 760,266 acres of these types. 



49. Limestone valleys and uplands. — Limestone soils 

 are not generally regarded as good truck soils, although 

 they often produce excellent results. Cantaloupes are 

 grown on silt loam in the Highland river region of Ten- 

 nessee. The fine sandy loam of the Cumberland series is 

 adapted to vegetables. The silt loam of the Decatur 

 series is especially well adapted to cantaloupes. A variety 

 of late garden crops is grown successfully on the 

 Hagerstown series. 



50. Glacial and loessial regions. — U. S. Bureau of 

 Soils, Bui. 55, p. 143 : "North of a line passing through 

 northern New Jersey, northwestern Pennsylvania, 

 southwestward through Ohio to Cincinnati, crossing the 

 Mississippi river at St. Louis, following the south side 

 of the Missouri river into Montana, where it crosses the 

 Canadian boundary line, then dips southward into Idaho 

 as a long lobe in the mountainous nonagricultural region, 

 and crosses the northwestern part of Washington, in- 

 cluding the Puget Sound region," there are 8,057,686 

 acres of glacial and loessial soils. 



51. Marshall series. — Of sand and fine sand, there are 

 107,008 acres. These types are well adapted to truck crops.
