Soda is compared with cotton-seed meal; in all cases the 

 plots were liberally supplied with phosphoric acid and 

 potash. The average yield of four plots in each instance J 3S 

 amounted per acre to 49.4 bushels for 

 Nitrate of Soda, and 40.1 bushels for otto?seed 

 cotton-seed meal, a gain for Nitrate of M ea n com- 

 Soda of over 23 per cent. A similar pare d on Wheat, 

 experiment with oats gave a return of 

 60 bushels for Nitrate of Soda and only 42 bushels for 

 cotton-seed meal, a gain for Nitrate over cotton-seed 

 meal of nearly 43 per cent. The Bulletin recommends, 

 even when cotton-seed meal is used in the complete 

 fertilizer, to employ Nitrate of Soda as a top-dressing 

 in the spring. 



Three hundred pounds per acre more Wheat, Oats, 

 Rye or Barley may be raised by the use of 100 pounds of 

 Nitrate of Soda used as a top-dressing on the soil. 

 Frequent trials at Agricultural Experiment Stations the 

 world over fully prove this to be so.

Comparison of Nitrate of Soda and Sulphate of 

 Ammonia Both With and Without Lime. 



As has already been explained, Nitrate of Soda 

 and Sulphate of Ammonia represent the mineral sources 

 of Nitrogen commonly found on the market. The 



* Gain of 7.8 bushels, or 75 per cent.
