bemes, and cabbage are the most important crops gro^Ti. The sum- 
mer and fall crops are chiefly corn or corn and cowpeas. There is 
abmidant evidence that the Portsmouth sandy loam and fine sandy 
loam are well suited to potato growing when good drainage can be 
provided. Large crops are obtained at nearly as early a date as 
upon the fine sandy loams of better natural drainage. 
It is thus apparent from a study of the soils of the Norfolk trucking 
district that fine sandy loam soils dominate in total extent and are 
the preferred soils for truck-crop production. ' The Norfolk fine sandy 
loam is the most important trucking soil. Upon it the greater part 
of the early Irish potato crop is grown. It is an important cabbage 
soil. Strawberries are successfully grown. Snap beans, peas, cu- 
curfl-bers, radishes, beets, and cauhflawer are also groTSTi. It is used 
in summer for egg plant, tomatoes, and cantaloupes. It carries a 
large acreage of kale and spinach in the winter months. 
The Sassafras fine sandy loam is of much less extent, but is also a 
highly prized trucking soil. Its crop uses do not differ materially 
from those of the Norfolk fine sandy loam. 
The coarse sandy loams are of decidedly smaller extent than the 
fine sandy loams in the district. They are very fully occupied for 
truck crop production', especially for the growing of the winter crops 
of spinach and kale. Strawberries cover the largest acreage in the 
areas mapped, but this is not held to be the general rule. Potatoes 
are not grown on either the Norfolk or Sassafras coarse sandy loam 
to as great extent as upon the fine sandy loams. Cabbage and snap 
beans are important crops. 
The loam soils differ with respect to truck-crop production. The 
small areas of weU-drained Sassafras loam are occupied nearly to 
their full extent for the growing of strawberries, cabbage, and spinach. 
The Norfolk loam, not usually well drained, is largely forested or used 
for the growing of general farm crops. Strawberries, potatoes, cab- 
bage, and spinach are successfully grown on the best-drained parts 
of the type. 
The gravelly loams are of very limited extent in the district and 
are not esteemed for trucking. 
. Large areas of the soils of the Keyport, Suffolk, and Portsmouth 
series remain in forest. Well-located areas, either drained or capable 
of drainage, are available for truck-crop production, especially for 
growing potatoes, strawberries, and cabbage. 
Limitations in drainage, caused by position and soil texture, 
chiefly control the distribution of truck-crop production in the Nor- 
folk district and strongly influence the. distribution of the various 
crops upon the well-drained and moderately drained types of soils.
