THE ADVANTAGES FROM CAPITAL 89 



"It is shown in the experiments conducted with nitrate 

 of soda on different crops that in the case of grain and forage 

 crops, which utilized the nitrate quite as completely as the 

 market garden crops, the increased value of crops due to 

 nitrate does not in any case exceed $14 per acre, or a money 

 return at the rate of $8.50 per 100 pounds of nitrate used, 

 while in the case of the market-garden crops the value of the 

 increased yield reaches, in the case of one crop, the high 

 figure of over $263 per acre, or at the rate of about $66 per 

 100 pounds of nitrate." (New Jersey Agricultural Ex- 

 periment Stations, page 8, No. 172.) 



Professor Voorhees, of the same station, experimented 

 with tomatoes, with these results : 



Such common crops as tomatoes, cabbage, turnips, beets, 

 etc., in order to be highly profitable, must be grown and 

 harvested early; any one can grow them in their regular 

 season ; their growth must be promoted or forced as much as 

 possible, at the time when the natural agencies are not 

 active in the change of soil nitrogen into available forms, and 

 the plants must, therefore, be supplied artificially with the 

 active forms of nitrogen, if a rapid and continuous growth 

 is to be maintained. 



It is quite possible to have a return of $50 per acre from 

 the use of $5 worth of nitrate of soda on crops of high value, 

 as, for example, early tomatoes, beets, cabbage, etc. This 

 is an extraordinary return for the money and labor invested ;
