SOIL CLASSIFICATION 



SOIL ADAPTATION OF FIFTEEN CROPS COMMON TO NORTHEASTERN STATES (Continued). 



Following the plan of Dr. Bonsteel, the author has gone carefully 

 through the soil literature of the United States and summarized the crop 

 adaptations, the means of modifying soils and the fertilizers to apply 

 to them. This is given for the leading crops by regions as follows: (1) 

 The North Central region, covered mostly by the Glacial and Glacial 

 lake soils lying between Pennsylvania and the Dakotas, and north of the 

 Ohio and Missouri Rivers; (2) the South Central and South Atlantic 

 Coast region, comprising Delaware, Maryland, Virginia, West Virginia, 

 Kentucky and the Cotton Belt; (3) the Plains and Mountain region west 

 of the 97th meridian of longitude; and (4) the Pacific Coast region, in- 

 cluding the three coast states and most of Nevada. 



The following is a summary of the leading crops adapted to soils of 

 the North Central region: 



Sand. Good for very early truck and small iruits; fair for sugar 

 beets and poor for small grains. May be kept in grass to prevent drifting. 



Sandy Loam. Good for tobacco, truck, apples, beans, root crops, 

 fruit, and fair for hay, small grains and corn. 



Loam. Good for general crops, truck and fruit. 



Silt Loam. Finest corn soil ; good for small grains, hay, fruit, tobacco 

 and heavy truck, such as cabbage. 



Clay Loam. Best wheat soil; good for corn, oats, rye, barley, grass, 

 clover, alfalfa and fruit. 



Clay. Good for hay, small grains, export tobacco, some fruit and 

 small fruit. (For continuation see next page.) 



The following is a summary of the leading crops adapted to soils of 

 the South Central and South Atlantic Coast region: 



Sand. -Adapted to earliest vegetables, some fruits and some varieties 

 of grapes. Small grains may be grown, but do better on heavier soils.
