Nitrate was used in three applications. An application of ^o^'^ ^^^ 



300 pounds of Nitrate resulted in a yield of thirteen and ^° ^^ 



one-third tons per acre. 57 



Catch-crops are recommended to pre- Catch-Crops, 



vent losses of available plant food after 

 crops are removed. Rape, Italian rye grass, Rye, Thousand- 

 headed kale and clovers are suitable. All these should 

 be top-dressed with from 100 to 200 pounds per acre of 

 Nitrate of Soda, depending upon the exhaustion of the soil. 

 In the remarks on the use of Nitrate in this sketch, we have 

 taken it for granted that our readers fully understand that 

 Nitrate alone is not a complete plant food. In all cases 

 where Nitrate has been recommended, phosphoric acid and 

 potash are to be used, unless the soil contains ample 

 supplies of both.

(Bulletin 44, Georgia Agricultural Experiment Station.) 



This bulletin gives in detail the results of experiments 

 on wheat with fertilizers, in which Nitrate of Soda is com- 

 pared 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 amounted per 

 acre to 49.4 bushels for Nitrate of Soda, -.x., . , 

 and 40.1 bushels for cotton-seed meal, a ^ ,, ,

turn of 00 bushels for Nitrate of boda and 



only 42 bushels for cotton-seed meal, a gain for Nitrate 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 for each 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. 



Barley. 



This crop does best on a strong clay loam, but the soil 

 must not be rich in organic matter. Soils naturally rich in
