Fertilizers Applied to Timothy on Corn Crop. jQi 



While there is no case in which there was no gain when both ear corn 

 and stover are considered, the single applications of fertilizers with the 

 exception of muriate of potash were least effective. The potash, when 

 applied singly at the rate of 80 pounds per acre, has produced a gain of 

 $11.28. This, as has been stated, was due partially to the preceding 

 heavy growth of alsike clover on this plat. Substantial gains have been 

 made when the fertilizers were added in combinations of two, yet the 

 most marked gains followed the application of a complete fertilizer. 



The large increases resulting from nearly all of the combinations of 

 fertilizers added emphasize very strongly this lasting or residual effect 

 of fertilizers, and particularly the greater productiveness following the 

 use of fertilizers on grass land. 



influence of lime on the action of fertilizers 



The north halves of all the plats were treated with lime at the rate 

 of 1,000 pounds per acre. The application was made by placing a 

 weighed quantity of caustic lime on each plat, covering this with earth 

 until slaked and then spreading uniformly. Plats 711-732 received 

 this treatment on September 15, 1903. This was before the plats were 

 seeded to timothy. Plats 701-710 received the lime on May 28, 1908, 

 which was after the timothy crop had been plowed for corn. In all 

 cases the lime was harrowed under. 



Owing to the topography of the plats a comparison of the growth 

 on the north and south halves of all of them would not give reliable 

 data from which to judge of the effect of the lime. This is in part 

 true of Plats 701-710, but as the other plats had been treated with 

 lime on the north halves it was thought best to give these similar treat- 

 ment. There are certain plats of which the topography is such that 

 a comparison of the growth on the north and south halves may be made 

 with some degree of fairness, but it would not be safe to draw more 

 than tentative conclusions from the data afforded. 



When the green fodder was cut the yields on the north and south 

 lialves were weighed separately, On these plats the yields were in 

 every case greater on the limited areas, but it must not be concluded 

 tiiat the difference is due to the effect of the lime. So far as the history 

 of the land can be traced it seems likely that the land constituting 

 tlie north ends of these plats was formerly in pasture while the remainder 

 was under cultivation. 



All of these plats, except the checks, received either complete fertilizer 

 or farm manure. The question arises, does the use of lime increase the
