SOILS OF SOUTHERN NEW JERSEY AND THEIR USES. ; 65 
Eggplant.—Nearly the entire acreage of this crop was found on 
- the Sassafras sand, 26.6 acres out of a total of 36.1 acres being mapped 
on this type. 
Onions —Nineteen out of a total of 32.3 acres of onions were 
mapped on the Sassafras sand. The Sassafras coarse sandy loam 
carries the next largest area, 7.6 acres. 
SUMMARY OF SELECTIVE USES AS SHOWN BY THE MAPS. 
‘The selective uses of soils in southern New Jersey, as illustrated by 
these detailed maps, may be briefly summarized: 
(1) For the production of Irish potatoes, the Sassafras loam is 
the soil preferred over all other types and classes. A sandy loam soil, 
like the Sassafras sandy loam or the Collington sandy loam, may be 
used, particularly for an early crop. Sandy soils are distinctly 
avoided. 
(2) The sweet potato crop is produced to the best advantage upon 
sandy soils or upon rather coarse sandy loams. Taking into consid- 
eration the quality of the product, the Colts Neck loamy sand is a 
leading type. If only considerations of yield are taken into account, 
then the Sassafras coarse sand and coarse sandy loam are the most 
important soils for growing the crop. The sandy loams of the series 
may also be used. 
(3) Tomatoes are grown for two distinct purposes, market and — 
canning. The early tomatoes are largely grown on the Sassafras 
sand, coarse sandy loam,and sandy loam. The later crop for canning 
is grown on the Sassafras loam and upon the Collington fine sandy 
loam and sandy loam. The latter fact is not brought out by the 
tables, but appears from a reconnoissance of the general region. 
(4) Sandy soils are preferred for asparagus. The Sassafras sand 
is a leading type in its production. The Colts Neck loamy sand is 
second in importance. 
(5) Cantaloupes are chiefly grown upon the Sassafras sand, with 
the Sassafras coarse sandy loam also constituting an important type 
for this crop. 
(6) Cabbage is distinctly a crop to be grown upon the finer tex- 
tured and more retentive soils, such as the Sassafras loam. 
(7) The other minor crops were not sufficiently well represented 
within the limits of the survey to permit of general conclusions.
