254 The Sugar-Beet in America 



course, it is not practical to return all by-products to the 

 land, but with care the greater part may be conserved. 

 The increased yield in crops brought about by beet 

 raising is due in part to the better farming methods dis- 

 cussed in the previous section. 



In order to realize the full value of sugar-beets in in- 

 creasing crop yields, it is necessary to have well-planned 

 rotations supplemented by an economical use of farm 

 manure or other fertilizing materials. The high yields of 

 European countries would not be possible without scien- 

 tific rotations and the extensive use of manures. 



EDUCATIONAL VALUE 



The beet-sugar industry is based on technical skill. 

 The breeding of strains of beets high in sugar calls for 

 special training in the principles of breeding. Many 

 chemists are needed to analyze the mother beets and special 

 skill is required in the field work. In the making of sugar 

 from beets, engineers, chemists, and other technically 

 trained men are required. This means that any com- 

 munity having a beet-sugar factory must have trained 

 men to carry on the industry. This necessity so promotes 

 education that sugar-beet production has a direct educa- 

 tional value to any community. 



Farmers take up better business methods, being en- 

 couraged to keep records by cost of labor, cash product, 

 contract crop, and contract labor, also because of its being 

 one of two or three general crops that can pay on high- 

 priced land.
