quantity of nitrogen applied to the two sets of plots is 

 substantially the same, while the plots receiving the lighter 

 application of potash annually receive an application of 

 acid phosphate at the rate of about 1,100 pounds per acre, 

 and the plots receiving the larger amount of potash receive 

 acid phosphate at the rate of about 200 pounds per acre. 

 The fertilizer applied where the lesser amount of potash 

 is used is substantially the same in its composition as 

 average corn fertilizers ; while the other, as will have been

noted, contains far less phosphoric acid and much more 

 potash. 



The kind of potash salt to be selected for clover is a mat- 

 ter of much importance, and experimental results at Amherst 

 have indicated again and again that the sulfate is likely to 

 prove decidedly superior to muriate or to kainit. The cuts 

 presented herewith illustrate the difference in the growth of 

 clovers on the two salts in a striking manner. These two 

 plots were side by side, and both had been manured with 

 equal quantities of fine-ground bone and potash for some 

 eight or ten years. The growth on the sulfate of potash, it
