Plot 1 ><i this fxpcriiiiciit ciijoyt'd ihc benefit of liead-lunds made in plowing and 

 the tramping- hy the horses in turning at the ends, and the result is in the case of 

 corn and beans a larger yield. Mr. Phillips reports an extremely dry season in this 

 locality, and it is safe to "assume that the full benefit of the fertilizers was not enjoj'ed 

 owing to a lack of water. Plot 4 was in a low place where the beets were planted, 

 and for some unaccountable reason the beets were very small on this particular area. 

 The experiment will be repeated, and it is hoped that more satisfactory results will 

 be obtained.

The extreme uniformity of yields from these plots indicates that the fertilizer was 

 not in any measure assimilated by the plants. Stable manure was applied very late, 

 and was somewhat coarse in character. It is safe to assume that in this light soil 

 the crops suffered on the manured plot because of being cut off from the capillary 

 moisture by the coarse stable manure plowed under just previous to sowing the crop. 

 The experiment will be continued another year. 



THE J. Y. CLARK EXPERIMENT OAKLAND COUNTY. 



This experiment was conducted on clay loam soil, sloping slightly to the south, 

 appearing when the experiment was begun to be of a very uniform character. Beans, 

 beets, corn and potatoes were planted. The beet seed, however, absolutely refused to 

 grow. The fertilization aiul arrangement of the plots was in accordance with a general 

 plan, one plot being added witli complete fertilizer and one ton of air slaked lime per 

 acre. 



Observations during the growing season revealed many facts in relation to the 

 character and contour of the laiul, which, together with the extreme dry weather, 

 detracted materially from the value of the results. Mr. Clark's notes state that the 

 chances on plots 7 and 8 are as 3 to 5. In another place there appeared a little sag, 

 giving a slight advantage to that particular area, while a dry, clay knoll, on which 

 the vegetation grew ])Oorly, cropped out on another plot. Stable manure and complete 

 fertilizers generally increased the yield, while an application of one ton of air-slaked 

 lime per acre added thirty i)er ceni to the yield of corn.
