*Fertilizers applied this year. 



The plots have been treated during the seven years from 1888 

 to 1894 inclusive as shown by the summary given below : 



Crop produced. 



Grass. 

 Grass. 



Peas and barley. 

 Oats, seeded down. 

 Barley, cut for hay. 

 Summer fallowed and tilled. 

 Oats, cut green for silo. 



Tear. ilanuring. 



1888, No fertilizer, 



1889, No fertilizer, 



1890, Fertilizer applied, 



1891, No fertilizer, 



1892, No fertilizer, 



1893, No fertilizer, 



1894, No fertilizer. 

 It seems that during seven years the plots have produced six 



crops, have received one application of the fertilizers and have been 

 summer tilled once. Two years were allowed to elapse before any 

 fertilizer was applied, during which time the grass crop was cut 

 and the hay weighed, in order to ascertain the relative natural pro- 

 ductiveness of the plots before receiving special treatment. 



The above figures effectually answer the question so often pro- 

 posed by farmers, "Do commercial fertilizers have influence upon 

 more than the first crop succeeding their application ?"
