EXPERIMENTAL FARMS 



■ 5 GEORGE v., A. 1915 



It would not be wise to draw hard and fast conclusions from one year's work, but 

 a careful consideration of the data in the foregoing tables shows that there are a few 

 inferences, broad and fundamental in character, that may be safely and legiti- 

 mately made. To present these deductions in a form that may be readily 

 grasped. Table III has been prepared. It gives for each series, the data for the plot 

 showing the net maximum cash r€ceipt, from which is subtracted the average value of 

 the crop without fertilizers. The table allows of deductions respecting the increases in 

 profit from the use of fertilizers in general. It ' also furnishes interesting and 

 valuable figures representing the respective profits and losses from the employment of 

 any one element, any two elements and from the use of all three elements in the 

 formula.

* Profits and losses have been calculated from the marketable crop only. 



Though in the series at Kentville but one case of actual loss from the applica- 

 tion of fertilizer occurred there are several instances in which the margin of profit 

 from its use is exceedingly small. At Fredericton four fertilized plots gave no 

 profit, yet on the same area, on apparently similar soil we find several plots upon which
