 with both phosphoric acid and potash. 



In ai)pearance the l^eans grown upon potash were hirger 

 and phimper than those grown upon either phosphoric acid 

 or nitrogen. 



Manuring the Corn Crop. 

 1. Manure alone v. 31anure and Polash. 



The past is the sixth year of continuous culture of corn 

 upon the same acre of land for the purpose of testing the 

 relative value of an application yearly of a small quantity of 

 manure with muriate of potash, as compared with a larger 

 application of manure alone. When manure alone was 

 applied, it was put on at the rate of G cords per acre, being 

 spread broadcast after ploughing, and harrowed in. The 

 manure and potash similarly applied have been put on at 

 the rate of 4 cords of the former and 160 pounds of muriate 

 of potash for the latter. 



The plats, four in number, contain one-quarter of an acre 

 each. The results are shown below : — 



Plat 1, manure, 8,115 pounds: stover, 1,600 pounds; ear corn, 



1,530 pounds. 

 Plat 2, manure, 5,354 pounds; muriate of potash, 40 pounds: 



stover, 1,300 pounds; ear corn, 1,455 pounds. 

 Plat 3, manure, 8,981 pounds: stover, 1,255 pounds; ear corn, 



1,450 pounds. 

 Plat 4, manure, 5,711 pounds; muriate of potash, 40 pounds: 



stover, 970 pounds; ear corn, 1,120 pounds. 



In plats 3 and 4 the corn was planted in hills, while in 1 

 and 2 it was planted in drills. This no doubt accounts in a 

 measure for the considerable difference in yield. The in- 

 feriority of the crop from plat 4 is due to the fact that, 

 from force of circumstances, poorer manure was used upon 

 it in 1895 than upon the other plats. 



Averaging the results upon 1 and 3 and upon 2 and 4, we 

 find the yields have been at the following rates per acre : — 



With manure alone : stover, 5,710 pounds ; grain, 73^ bushels. 

 With manure and potash : stover, 4,540 pounds ; grain, 64f bushels-
