THE CLYDE LOAM. 15 



Grass occupies the most extensive acreage of any crop grown upon 

 the Clyde loam. The yields are high. 



Both winter and spring wheat are commonly grown, with medium 

 to low yields per acre. In all of the eastern areas the area devoted 

 to wheat is decreasing. 



Oats constitute an important small-grain crop upon the Clyde 

 loam, giving an average yield in excess of 40 bushels per acre. 



Corn is extensively produced in the lower latitudes, giving average 

 yields of about 35 bushels per acre, with many instances of higher 

 yield. 



Sugar beets constitute the principal special crop grown on the 

 Clyde loam, and this type is probably the best suited to the produc- 

 tion of sugar beets of any soil to be found in the eastern States, 

 within the climatic zone suited to beet production. The yields per 

 acre are good and the percentage of sugar content and of purity high. 



Beans, rye, and buckwheat constitute minor crops of local im- 

 portance only. 



The Clyde loam is also suited to the production of cabbages, 

 onions, celery, and late strawberries, of which the first crop is the 

 most important. Peppermint was formerly grown to some extent 

 upon the type in Michigan. 



The Clyde loam has been reclaimed and occupied for agricultural 

 purposes to the extent of probably 80 per cent of its total area in all 

 of the eastern localities where it is found, and the remainder of the 

 type is also used for pasturage, the cutting of wild hay, and, to a 

 very minor extent, for the firewood and timber growing within the 

 swamps. 



In North Dakota little effort has been made to perfect the drain- 

 age of the type, and the amount of the Clyde loam devoted to crop 

 production varies decidedly with seasonal variations in rainfall; in 

 seasons of scant precipitation practically all of its area is devoted 

 to the production of spring wheat, with an average yield of about 

 13 bushels per acre, while in a season of excessive precipitation 

 little of the type is sowed to wheat or else the crop yields are de- 

 cidedly low. 



For its proper tillage the Clyde loam requires heavy teams and 

 improved machinery. 



Owing to the special adaptation of the type to the production of 

 grass, oats, and corn, a considerable proportion of it is occupied by a 

 very successful dairy industry. 



Approved.
