Analyses of the above fertilizer will be found on page 330. 



This experiment being tried on land comparatively rich in organic matter, it having 

 for several years previously been occupied by a growth of lathyrus sylvestris, and this 

 being the first year, these results are in no way conclusive. It might, however, be 

 observed that the land responded to every application of fertilizer, as shown by 

 increased yields over the no-fertilizer plot, and that the phosphoric acid seemed to be 

 the most beneficial. It is unsafe, however, to draw any conclusions as yet from the 

 effect of fertilizing elements on the content of sugar. This experiment will be con- 

 tinued on the same ground, using similar fertilizers. 



EXPERIMENT B. 



A co-operative soil test experiment has been conducted the past season in which 

 sugar beets were one of the several crops. Below are the names of men who con- 

 ducted successful experiments with sugar beets: 



*0. C. Wheeler, Belding, Ionia county; L. B. Walton, Dryden, Lapeer county; 

 Bruce Phillips, Utica, Macomb county; Glen C. Lawrence, Ypsilanti, Washtenaw 

 county; H. M. Kingsley, Kendall, Van Buren county; *C. E. Mills, Mancelona, Antrim 



* Beets were not analyzed.
