HATCH EXPERIMENT STATION. [Jan. 



dressing of manure in December, 1894, at the rate of 7 cords 

 per acre. We used fertilizers, mixed and applied in the drill 

 at the following rates per acre : — 



Pounds. 



Nil rate of soda, 120 



Dissolved bone-black, . . . . . . . 187 J 



Sulphate of potash (high grade), 105 £ 



Tankage, 120 



Dried blood, 30 



Manure alone v. Manure and Potash for Corn. 

 The experiment to test the value of manure and potash as 

 compared with a larger quantity of manures alone for the 

 corn crop has been continued, the past being the fifth suc- 

 cessive year of similar treatment. Where manure alone was 

 used we applied at the rate of 6 cords per acre, spread after 

 ploughing and harrowed in. The manure and potash siini- 

 larly applied have been put on at the rate of 4 cords of the 

 former and 160 pounds of muriate of potash for the latter. 

 The plats, four in number, contain one-quarter of an acre 

 each. The results are shown below : — 



Plat No. 1, manure, stover, 1,367 pounds; corn on the ear, 1,227 pounds 

 Plat No. 2, manure and potash, stover, 1,223 pounds; corn on the ear, 



1,065 pounds. 

 Plat No. 3, manure, stover, 1,025 pounds ; corn on the ear, 1,266 pounds. 

 Plat No. 4, manure and potash, stover, 987 pounds ; corn on the ear, 



1,160 pounds. 



The manure used was made by cows, that applied to Plat 

 4 being not as good as that applied to the other plats. 



The application made furnished plant food at the following 

 rates per acre : —

It a\ ill bo noticed that where manure alone was applied 

 considerably more nitrogen and phosphoric acid have been 

 supplied than on the other plats, while the quantity of pot-
