EXPERIMENT STATION 



[Jan. 



This field was limed in 1900 at the rate of 1 ton to the 

 acre. 



The crop of the j^ast season was mixed grass and clover, 

 the present being the second year for this seeding. The 

 rates of yield per acre on the several plots and the averages 

 for the two systems of mannring are shown by the following 

 tables : —

Average Yields per Acre {Tounds). 



It will be noticed that the combination of fertilizers rejD- 

 resenting the sj^ecial corn fertilizer gives an average yield 

 of hay at the rate of 430 pounds per acre heavier than that 

 prodnced where the combination of fertilizer materials richer 

 in potash was nsed. On the other hand tlie latter combina- 

 tion of fertilizer materials gives a yield of rowen averaging 

 260 ponnds j)er acre greater than the special corn fertilizer. 

 The total cro^DS, then, prodnced nnder the tw^o systems of 

 fertilizing, are not far from equal for the past year. 



Since this experiment was begnn, this land has prodnced 

 on plots 1 and 2, ten corn crops ; on plots 3 and 4, eight corn 

 crops. The average yields per plot and the averages for 

 the two systems of fertilizing are shown in the following
