These comparisons show clearly that nitrate of soda was most 

 beneficial on this soil. This result, contrary to that obtained in most 

 of our experiments with corn, may perhaps have been due to the 

 poverty af this soil in organic matter, the decay of which could fur- 

 nish the nitrogen needed by the crop. That the potash usually so 

 beneficial on soils of this class, should have failed to benefit the crop 

 cannot easily be accounted for. 



THE RESULTS OF THE ADDITION OF POTASH TO BARN- 

 YARD MANURE FOR CORN. 



In bulletin number 14, of this station, (p. 60) among other conclu- 

 sions will be found the following : " With ordinary barn-yard or stable 

 manure for corn, use potash. I would recommend using about four 

 cords of manure and one hundred pounds of muriate of potash j^er 

 acre." 



This advice was given in view of the results of two seasons' work 

 in testing soils in various parts of the state (full accounts of which 

 will be found fn bulletins 9 and 14) but it was thought best to test 

 the method upon our grounds. Further deliberation and consulta- 

 tion with representative farmers, led to a slight modification in the 

 quantities both of manure and fertilizer. It was decided to use the 

 manure at the rate of three cords and the potash at the rate of 124 

 pounds per acre, in comparison with twice the above named amount 

 of manure alone per acre.
