COMMKNTS ON FkUTIMZKR ExTKRIMKNTS. 



The results of fertilizer experiments for a single year admit of 

 searcely any general conclusions, yet on some points these experi- 

 ments by farmers strongly corroborate the testimony of practice. 



(1) A moderate (juantity of a commercial fertilizer does in some 

 instances produce a large increase of crop. 



(2) This increase of crop for a single season varies greatly with 

 the locality. 



(3) A complete fertilizer, i. e., one consisting of a mixture of 

 nitrogenous, phosphatic and potash fertilizers, is the safest manure 

 with wliich to insure a crop, but is often much less profitable than a 

 fertilizer not containing one or two of the three valuable ingredients. 

 This fact is illustrated in a striking manner by the results of Mr. 

 Starrett's experiment, where the crop was increased nearl3' eight- fold 

 by the use of a mixture of phosphatic and potash manures, no fur- 

 ther increase being secured by the addition of sulphate of ammonia 

 to this mixture. 



(4) Except in the case of Mr. Deering's experiment, where the 

 land was in excellent condition, the ground bone failed to furnish 

 plant food as readily as the other materials used.
