SOIL TEST WITH FERTILIZERS FOR POTATOES, 



Station Grounds (North Acre). 



*t;ords. 

 Avei-age of the nothing plots : large, 21.2 bushels; small, 4.7 bushels per acre. 



This experiment was tried upon the north acre which served for a 

 soil test with corn in 1890. The soil is a warm medium loam, with 

 gravel at the depth of two to three feet. Previous to last year it had 

 been several years in pasture without manure. 



The seed was cut to two good eyes, and the pieces were planted 

 twenty inches apart in rows which were three and one-half feet apart. 

 The variety was the Beauty of Hebron and the seed was raised in 

 Aroostook county, Maine. It was planted April 21st. and the crop 

 was harvested Sept. 12th. The seed had been cut ready for plant- 

 ing about two weeks earlier ; but a heavy fall of snow, April 5th, 

 delayed the work. The result was that the seed sprouted unevenly 

 and considerable of it failed to make plants strong enough to live. 

 There were accordingly many vacant spaces in all the plots ; but as 

 these were about equally divided among the plots, no attempt at 

 correction for missing plants has been made. The crop was also 

 somewhat injured by frost.
