EXPERIMENT STATION. 



[Jan. 



It will be seen that the two forms of lime that have given the 

 best results for all crops are the hydrated lime and the limoid. 

 Although this is the fifth year since these plots received an 

 application of manure or fertilizer, the yield of grain this year 

 ranged from 48.2 bushels per acre of crib-dried corn on the no- 

 lime plot to 60.3 bushels on the hydrated lime plot. 



The soy bean is not a crop that draws heavily upon the 

 supply of soil nitrogen, yet both years when this crop was 

 grown the south half of each plot (that portion of the plot 

 which formerly received the application of manure in the spring) 

 looked better all through the growing season and produced the 

 larger crop at harvest. The same results were obtained this 

 year with corn, with the exception of one plot, as is shown in 

 the following table: — 



Considering the data obtained during the three years of this 

 experiment it would seem from the standpoint of crop produc- 

 tion that first place must be given to the hydrated lime. They 

 also show that land which has received annually a liberal ap- 

 plication of manure for several years will produce satisfactory 

 crops for some time without further fertilization.
