method of application (broadcast) is not the best. That the latter 

 is the case I cannot believe. I have already suggested that the 

 potash required by this crop should, in accordance with the general 

 practice, be offered in the form of sulphate rather than chloride, 

 although it is usually held that this is more important in its relation 

 to quality than to quantity . The chloride (muriate) may give as 

 large a crop ; but it will be of inferior quality. 



The increase in bushels per acre, caused by the use of five cords of 

 manure in the several experiments is as follows : — Hadley, large, 

 68.8, small, 9 ; Concord, large, 72.3, small, 6.2 ; Shelburne, large, 

 44.8 ; small, -2.8 ; Hadley, large, 77.7, small, -6.7; Amherst, large, 

 132.3, small, .8. The average increase in large potatoes is 79.2 

 bushels; the average net decrease in small potatoes is 2.3 bushels. 

 The average net increase then is 77 bushels, against 61.2 bushels for 

 the " complete " fertilizer. 



Viewed from the standpoint either of profit or recovery of plant 

 food applied to the soil, these results are even less satisfactory than 

 those with "complete" fertilizer.
