The late fertilizer application was 

 Late Fertilizer used in this case advisedly to check up 

 Applications Not this practice which is followed by many 

 Generally farmers, and which is rather against 



Advisable. our general advice as to very late dress- 



ings of Nitrate. Earlier applications on 

 corn, we are confident, will prove to be more profitable. 



Among interesting items secured are 

 Efficiency of the yields of protein per acre as tabu- 



Nitrate Alone. lated in the following tables. It is not- 

 able that the total ash mineral residue 

 per acre removed from the plot on which Nitrate alone 

 was used is less than on the check plot, and that the 

 exhaustion of phosphoric acid, potash and lime was at a 

 lower rate per acre on the Nitrate plot than on the check 

 plot. Notable also is the fact that the rate of yield of 

 protein was lower on the check plot and also on the acid 

 phosphate alone plot than on the Nitrate plot. Protein 

 is, of course, a factor of very high food value for dairy 

 stock. 



The results speak well for Nitrate not 

 Use of Nitrate exhausting soil fertility as to its mineral
