have obtained indicate that the conditions controlling the growth 

 of clover here are the same as those in other countries, where it 

 has long been known that clover follows potash. The farmer who 

 would raise more of this invaluable fodder should make sure that 

 his land is well stored with potash and phosphates. This plant 

 can draw much of its nitrogen from the air. An interesting result 

 of our experiments with fertilizers upon grass land is the demon- 

 stration afforded of the remarkable capacity of soils to hold even 

 soluble forms of potash and phosphoric acid. These do not ap- 

 pear to be diffused laterally to any considerable extent, remaining 

 just where they are placed. The line between clover and " no 

 clover " on adjoining plats, one of which had and the other had 

 not received any potash, has been as true as it could be drawn. 

 The clover comes up to the line and there stops short. 



The soil test with oats was quite unsatisfactory on account of 

 the lodging of the crop upon a part of the plats. Throughout 

 the early stages of growth the phosphoric acid appeared to be the 

 controlling element ; but upon threshing, it was found that the 

 plats which had received potash gave the largest yields. The re.- 

 sults, however, were quite indecisive on account of the injury 

 from lodging, due to heavy showers and wind. 



Manure alone versus Manure and Potash for Corn has been 

 under trial for the third year upon the same land. The applica- 

 tion where manure alone was used was at the rate of 6 cords per 

 acre. Where the manure and potash were used, we applied 4 

 cords of the former and 125 pounds of the muriate of potash. 

 The crop has not been husked, but appears to be very even, with 

 the probabilities in favor of the larger yield where manure alone 

 was applied. The application of 6 cords of manure costs $30. 

 Four cords of manure and the 125 pounds of muriate of potash 

 cost $22.65. The latter application will yield the greater profit. 



Special Corn Fertilizer has been under comparison with a home 

 mixture containing more potash. The crop is in the stack and 

 too nearly even to warrant an assumption of superiority for either. 



Drill and Hill Culture of corn have been compared upon one 

 acre, with the advantage clearly with the drill, though figures can- 

 not now be given. The seed germinated more quickly and better, 

 and the crop was much more clearly vigorous from the start. 



The Effect of sowing White Mustard in the standing corn early 

 in August has been under study upon one acre. The present is 

 the second year of this trial ; but the results are not yet striking. 

 In a series of years it is confidently believed the effect will prove
