Food for tYi^y gg(- i(-^ as before stated, from an excessive and continuous 



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 lOO 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. 



It has been found by experiments made at 

 oma oes. ^j^^ New Jersey Experiment Station for 



a period of three years, that Nitrate of Soda, applied when 

 the plants are set out, greatly increased their growth early in 

 the season and produced a much larger crop of early ripe 

 fruit than either barn-yard manure, "phosphates," or no 

 manure at all.

It will be noticed that 160 pounds of Nitrate of Soda, 

 •costing ^4.00, made an increase in the value of the crop of 

 ^92.03 per acre over the unfertilized land, and ^82.37 over 

 the land where 20 tons of barn-yard manure, costing $30.00, 

 was used. It will also be noticed that the addition of phos- 

 phate (bone-black) and potash had little or no effect. This 

 •<ioes not indicate that tomatoes do not require phosphoric 

 acid and potash, but that enough of these elements of plant 

 food was already in the soil. 



"The yield of early tomatoes was very decidedly increased by the use 

 ■of Nitrate of Soda, both alone and together with phosphoric acid and potash."
