productive influence of the manure and fertilizer? In other words, will 

 a fertiHzer when added to a Hmed soil increase the yield more than 

 when added to one deficient in lime, as this soil is known to be? In the 

 table which follows the increased yields on the limed section of the 

 fertilized and manured plats are compared with the increased yields 

 on the limed sections of the check plats, which received no fertilizers.

The plats, to the north halves of which li.r.e was added in the spring 

 of 1908, and which were manured for corn the same year also furnish 

 some data on this subject. These plats, so far as known, had been 

 treated in the same manner throughout in previous years. They are, 

 therefore, more likely to show the true effect of the lime. 



Arranging these so as to compare the increase or decrease in yield 

 on the limed sections of the fertilized or manured plats with the increase 

 or decrease in yield on the unfertilized plats we have the following 

 table.
