Note.— The cost of the fertilizer is assumed to be $25,00 per ton. 



It is eyident that if we consider tlie first year's crop only the 

 application of one ton of fertilizer per acre, or even 1,500 pounds, 

 was considerably less profitable than the use of 1,000 pounds. 

 The fertilizer cost of the small increase of product caused by 

 applying more than 1,000 pounds of fertilizer was much greater 

 than the market value of the potatoes, even in this year of good 

 prices. 



On the other hand the use of 1,000 pounds was very profitable, 

 the fertilizer cost of the increased yield on the Fleet and Hallock 

 farms being only 20 cents per bushel. Even if the merchantable 

 potatoes had been sold at 40 cents per bushel, there would still 

 be a reasonable margin of profit. It should be kept in mind that 

 these figures refer to the light soils and market conditions of 

 Long Island. 



The Influence of the Potash Salts upon the Composition 



OF the Potato. 



Much investigation has been carried on to determine whether 



a liberal application of muriate of potash has a depressing effect 



upon the proportion of dry matter and starch in the potato. The
