Food for superphosphate analyzes 14 per cent, of available phosphoric 

 ^^^°*^ acid, a ton would contain 280 pounds, and should not cost 

 24 more than $14.00 per ton. Thomas Phosphate Powder is 

 also an important Phosphatic Plant Food. 



The various "brands" of fertilizers are composed, for 

 the most part, of substances such as plaster, fillers, super- 

 phosphate, etc., which can be manufactured for much less 

 than the prices charged for these substances in so-called 

 "complete fertilizers."

distributor, and well mixed with the soil. This is best done 

 by running a cultivator along the row; or when a distributor 

 is used, an attachment in the form of a small cultivator can 

 be made to do the work at one operation. The potatoes 

 are then dropped in the furrow and covered. If it is thought 

 best to cultivate both ways, the land can be marked across 

 the furrows after the fertilizer is applied.

gram together contain about 1,500 pounds 



of dry matter, of which 25 pounds is Nitrogen. To produce 



a ton of wheat and straw together would require, therefore, 



170 pounds of Nitrate of Soda, in which quantity there is 



25 pounds of Nitrogen. 



A ton of cabbage, on the other hand, contains about 4! 

 pounds of Nitrogen. To produce a ton of cabbage, there- 

 fore, would require 28 pounds of Nitrate of Soda. 



The most important money crops are beets, carrots, 

 cabbage, cauliflower, celery, onions, tomatoes, potatoes and 

 other vegetables and fruits. The most profitable are tobacco, 

 grain, cotton, grass and alfalfa. 



There are no crops on which it is more profitable to usq 

 fertilizers than on vegetables and small fruits, provided they
