SOILS OF SOUTHERN NEW JERSEY AND THEIR USES. 4] 
Yet certain truck crops are discriminated against as markedly as 
these four are preferred for production on this soil. 
Trish potatoes only occupy 1.9 acres on the Sassafras sand, com- 
pared with 32.3 acres on the Sassafras sandy loam, or 13 per cent of 
its area; 13.3 acres on the Collington fine sandy loam, or 29.2 per 
cent of its area; and 9.5 acres on the Portsmouth sandy loam, or 7.7 
per cent of the area of that type. This distinction is in full accord 
with the conclusions reached in connection with the observations 
concerning the general region. | 
The acreage in cabbage | is concentrated on the Portsmouth sandy 
loam—a moist, low-lying soil—this crop appearing only to a limited 
extent on the Sassafras sand and the Collington fine sandy loam. 
The absence of anything but a purely accidental area of asparagus 
from all soil types except the Sassafras sand is decidedly significant. 

Fic. 20.—Sweet corn interplanted with string beans on Sassafras sand. 
Wherever possible the other soils of the area have been avoided for 
setting asparagus beds and only where small areas of other types 
were closely associated with this chosen asparagus soil is any acreage 
of the crop discovered. 
The contrast between the crop occupation of the Sassafras sand and 
the Sassafras sandy loam is marked. The former type is absolutely 
dominated by truck crops; the latter carried 51.1 per cent of its area 
in general farm crops. On the former, asparagus is the leading 
crop; on the latter, hay leads in acreage and corn is a close second.
