40. Hempstead Loam

This soil is of interest to vegetable growers because it is used to a considerable extent on Long Island. It is regarded as a fair soil for late truck.

41. Muck And Peat

In Florida and Louisiana, 65,558 acres. After drainage, muck and peat are highly valued for the culture of celery, onions, peppermint and cabbage.

42. River Flood Plains

United States Bureau of Soils, Bul. 55, p. 118: "An extensive and characteristic group of soils, usually known as 'bottom lands,' is found in the flood plains of numerous rivers and streams of the United States. The largest development of this group occurs along the Mississippi river, where the bottoms are often many miles in width." The most important series for trucking are Huntingdon, Miller, Wabash and Wheeling and the muck and peat soils.

43. Huntingdon Series

258,496 acres of the Huntingdon series are distributed. Through a dozen states, the loam and the gravelly loam are largely used in trucking.

44. Wabash Series

Wabash Series has 1,861,497 acres widely distributed. The loam can be used to advantage in growing canning crops, as sweet corn, tomatoes, peas and beans. The fine sandy loam is a good melon and potato soil and is also valued for other truck.

45. Wheeling Series

In Ohio and West Virginia, 20,032 acres. The gravelly loam has wide adaptation for truck crops. Melons and tomatoes are produced on the fine sand with marked results.

46. Muck And Peat

In Kentucky, Louisiana and Nebraska, 24,640 acres. These soils are highly valued for the production of celery, onions, peppermint and cabbage.

47. Piedmont Plateau

This area lies between the Atlantic 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 Tennessee. 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, Bul. 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, including 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.

52. Miami Series

The sand and the fine sand are the best early truck soils of this section. The stony and gravelly sandy loams are fairly good truck soils.

53. Miscellaneous Types

The Custer silt loam produces profitable yields of beets, peas, cabbage and other vegetables. Lexington silt loam is suited to vegetables. Lynden fine sandy loam is well adapted to cabbage, cauliflower, carrots, garden peas, cucumbers and other vegetables. Madison loam does well when planted in cabbage, tomatoes and other truck crops. Portage sandy loam and Portage silt loam are regarded as valuable for vegetables. Rhinebeck loam produces good crops of cabbage. Whatcom silt loam produces profitable crops of peas and cabbage and other garden crops.

54. Glacial Lake And River Terraces

U. S. Bureau of Soils, Bul. 55, p. 153: "Occurs in the glacial region, principally as terraces around lakes, or along streams or as deposits in areas which were formerly covered by water."

55. Clyde Series

When well drained, these soils are very productive. The loam is valued for cabbage and canning crops. The clay loam is extensively used for cabbage. "The fine sandy loam is a desirable truck soil and is admirably adapted to cabbage, tomatoes, peas, beans, cucumbers and potatoes." The gravelly sand and fine sand are suited to truck crops.

56. Dunkirk Series

The fine sand is valued for early crops. The gravelly loam gives large yields of beans and potatoes. There are large areas in New York and Ohio.

57. Muck And Peat

In this region, 532,842 acres. These soils are highly valued for the production of celery, onions, peppermint, cabbage and lettuce.

58. Pacific Coast

The sand and the fine sand of the Fresno series are valued for vegetables under irrigation. The Hanford series when well drained are good soils for vegetables. Truck crops do well on the sandy loam of the Maricopa series. The soils of the Oxnard series are particularly well adapted to lima beans and the industry has been extensively developed on these soils. The Pla-centia series is used for beans and other vegetables. The fine sandy loam of the Sacramento series is valued for vegetables and the loam of this area is also used. The sandy types of the Salem series are good vegetable soils. When irrigated, the San Joaquin series are valuable trucking soils, and vegetables are grown to some extent on the Stockton series. There are 110,163 acres of muck and peat soils of the Pacific Coast valued for the crops usually grown on these lands. Puget clay soil and Puget fine sandy loam have deficient drainage, but when well drained and protected from overflowing, truck crops and potatoes are successfully grown. Puget silt loam gives promise of becoming a highly prized soil for small fruits and vegetables.
