Food for gardener can get from 75 or 100 tons of well-rotted stable 



manure. The stable manure may 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. 



T, It has been found by experiments made at 



Tomatoes. 1 tvt t 1- • or 



the New Jersey Jixpcriment otation tor 



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. 



In the experiments conducted by the New Jersey 



Experiment Station on the farm of Mr. J. M. Gill, of 



Gloucester County, N. J., in 1891, the following results 



were obtained :

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

 costing I4.00, made an increase in the value of the crop of 

 $92.03 per acre over the unfertilized land, and I82.37 over 

 the land where 20 tons of barn-yard manure, costing I30.00, 

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

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

 This does not indicate that tomatoes do not require phos- 

 phoric acid and potash, but tljat enough of these elements 

 of plant food was already in the soil. Other experiments 

 made on poorer land showed that the phosphoric acid and 

 potash were necessary in addition to Nitrate ot Soda to 

 produce a full crop. In writing of these experiments. 

 Professor Voorhees, who conducted them, says : 



•• 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." ^f
