POTASH PAYS 



EXPERIMENT ON CELERY 



This experiment was made by W. E. Gerhard, Santa 

 Ana, Cal. It was conducted on loose reclaimed swamp 

 land which had produced a number of crops and was 

 evidently worn out so far as an " available" supply of plant 

 food was concerned. This is shown from the fact that the 

 yield was more than doubled by the fertilizer applications. 

 One third of the 90 crates increase produced from the 1300 

 pounds of the fertilizer used was due to Potash. 



The amount of fertilizer applied to each plot, the yield 

 and the amount of increase are shown in the following table:
