By rearranging part of the data contained in Tables VIII and X, the 

 effectiveness of the carriers of nitrogen, phosphorus, and potassium 

 appHed singly, in different quantities, or in combinations, can be studied 

 in a comparative way to better advantage. Table XI shows the apparent 

 increase, net gain or loss, and per cent of total weight in tops, for both 

 trials, also the averages for the two trials on fourteen of the twenty- 

 two fertilized plats. 



TABLE XI 



It will be seen that the greatest average apparent increase in yield 

 resulted from the use of a heavy application of fertilizer containing 

 nitrogen, phosphorus, and potassium, but owing to the greater cost 

 of this complete fertilizer, the net gain per acre was not so great as that
