How, then, is the market gardener to get the Nitrate Food for 

 absolutely necessary for the growth of his early plants? He Plants 

 may get it, as before stated, from an excessive and continuous X 9 

 use of stable manure, but even then he fails to get it in 

 sufficient quantity. 



One thousand pounds of Nitrate of Soda will furnish 

 more Nitrogen to the plants early in the spring than the 

 gardener can get from 100 tons of well-rotted stable manure. 

 The stable manure may help furnish Nitrate for his later 

 crops, but for his early crops the gardener who fails to use 

 Nitrate of Soda is blind to his own interests. 



A given quantity of Nitrate will pro- 

 duce a given amount of plant substance. A ~? 

 ton of wheat, straw and grain together, ' ate bl 

 contain about 1,500 pounds of dry matter, usecl - 

 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 4^2 

 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 use 

 fertilizers than on vegetables and small fruits, provided they 

 are used rightly. Many failures with chemical fertilizers are 

 caused usually by lack of knowledge. There . .
