way. An experiment conducted by Dr. J. M. H. Munro, ^^^'^ fo"" 

 of L3o\vnto\vn Agricultural College, Salisbury, for the 

 Permanent Nitrate Committee, gave a return of nearly ''^ 

 twenty and one-half tons per acre, from an increased Yield, 

 application of 600 pounds of Nitrate per 

 acre, supplemented bv phosphoric acid and potash. 1 he 

 Nitrate was used in three applications. An application of 

 300 pounds of Nitrate resulted in a yield of thirteen and 

 one-third tons per acre. 



Dr. Bernard Dyer recommends catch- Catch-Crops 

 crops, to prevent losses of available plant 

 food after crops are removed ; for this use he recommends 

 Rape, Italian rye grass. Rye, Thousand-headed kale and 

 clovers. All these should be top-dressed with Nitrate of 

 Soda, from 100 to 200 pounds per acre, depending upon 

 the exhausted condition 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, it is also to be understood that phosphoric 

 acid and potash are to be used, unless it is known that the 

 soil contains ample supplies of these elements of plant food.

(Bulletin 44, Georgia Agricultural Experiment Station, 

 September, 1899.) 



This bulletin gives in detail the results jy|jjj.gjg ^^^ 

 of experiments on wheat with fertilizers, in r:Qt»Qj,speH 

 which Nitrate of Soda is compared with ^ . ^ 

 cottonseed meal, in all cases the plots were p^^ed on Wheat, 

 liberally supplied with phosphoric acid and 

 potash. An average of four plots each gives an acre yield 

 of wheat for Nitrate of Soda 0^49.4 bushels, for cottonseed 

 meal 40.1 bushels, a gain for Nitrate of Soda of something 

 over 23 per cent. A similar experiment with oats gave a 

 return of 60 bushels for Nitrate of Soda and only 42 bushels 

 for cottonseed meal, a gain of nearly 43 per cent, for Ni- 

 trate. The Bulletin recommends, even when cottonseed 

 meal is used in the complete fertilizer, to use Nitrate of 

 Soda as a top-dressing in the spring.
