SOILS OF SOUTHEEN 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 Xew 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 sand}^ loam or the CoUington 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 «pon 

 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 CoUington 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.
