As the local conditions of the soil and the composition 

 of the individual characteristics of the plants to be raised 

 deserve especial attention, when selecting from the above- 

 stated commercial manurial substances the constituents for 

 the fertilizer mixtures to be used, it cannot be considered 

 judicious to recommend any particular combination as being 

 unfailing and best in all cases. For this reason it has been 

 thought best to state in this connection, as a mere matter 

 of illustration, a few combinations of manurial substances 

 which served us well, as may be noticed from a few preced- 

 ing annual reports, — State Experiment Station, 1893, pages 

 241 to 261 ; and 1894, pages 274 to 285. 



The amount of fertilizer recommended per acre, under fair 

 conditions of the soil, contains : — 



Pounds. 



Available nitrogen, 60 



Available phosphoric acid, . . . ... .60 



Available potash, 120
