IX. — Experiment in the Application of Manure. 



Full details with reference to the plan followed in this ex- 

 periment will be found in the nineteenth annual report. Briefly 

 stated, the object is to compare results obtained through spread- 

 ing manure as it is removed from stables during the winter 

 with the practice of storing in a heap in the open air imtil 

 spring and then spreading. The field which is used in this 

 experiment slopes quite rapidly toward the west. The experi- 

 ment was begun in 1899 ; the past season, therefore, is the 

 ninth during which the experiment has continued. The crop 

 this year was mixed grass and clover, sown in the standing 

 corn of the previous year. No manure was applied either in 

 winter or spring this year, as it was apparent that the land, 

 which has been manured annually at the rate of 6 cords to 

 the acre for the past eight years, would produce as rank a 

 growth as was desirable. The rates of yield per acre and the 

 relative standing of the several plots are shown in the following 

 table : —

1, These yields of rowen less accurately measure the fertility than the first crop, for the 

 grass and clover both were unevenly killed in spots by the lodging of the first crop.
