40 a EXPERIMENT STATION. [Jan. 



On the basis of increase as compared with the no-nitrogen 

 plots the relative standing for the different fertilizers for the 

 twenty-six years is as follows : — 



Per Cent. 



Nitrate of soda, . . . " 100.00 



Manure, 76.47 



Dried blood, . 75.83 



Sulfate of ammonia, . 57 . 93 



Considering the relative standing of the different nitrogen 

 fertilizers on the basis of yields per acre, it will be seen that 

 with a mixed crop of clover and grass there is very little differ- 

 ence between the different materials, and that the no-nitrogen 

 plots gave yields about as large as those receiving nitrogen. 



Comparison of Muriate and High-grade Sulfate of Pot- 

 ash (Field B). 



The crops grown on this field the past year were asparagus, 

 blackberries, raspberries, currants, rhubarb, potatoes, mangels 

 and alfalfa. The results obtained are in agreement with those 

 in previous years, with one exception, — the yield of asparagus 

 this year was slightly better on the sulfate plot than on the 

 muriate plot. This is the twelfth year this crop has been grown 

 on these plots, and the only time that the yield has not been 

 decidedly in favor of the muriate. We have pointed out in 

 previous reports the fact that muriate has given better results 

 in dry seasons, but we are not ready to say the difference in 

 yield this year is due to the abnormally wet season. 



Considering the different crops grown during the twenty- 

 three years of the experiment, the muriate has proved the better 

 source of potash for the following: asparagus (eleven years), 

 currants (four years), mangels (two years), sugar beets (one 

 year), corn, ensilage (one year), corn stover (seven years), 

 sweet corn stover (one year), squashes (three years), carrots 

 (two years), onions (two years), celery (one year), oat hay (one 

 year), and vetch and oats (two years). 



The sulfate has proved the better source of potash for the 

 following crops: asparagus (one year), blackberries (ten years), 

 raspberries (ten years), strawberries (eleven years), rhubarb
