CORN. 29 



The Results of the Addition of Potash to Barn-Yard Manure 

 FOR Corn. Bulletin No. i3, April, 1892, page 87. The result ob- 

 tained by barn-yard manure was compared with that obtained by 

 the application of a smaller quantity of barn-yard manure mixed 

 with potash salts. 



"These figures and comparisons show that the manure alone pro- 

 duces slightly the better crop, but estimating manure at $5 per cord 

 and muriate of potash at $45 per ton, shelled corn at 65 cents per 

 bushel and stover at $5 per ton, we find that the manure and potash, 

 although producing a slightly less valuable crop, gave a financial 

 result nearly $9 better than manure alone." 



Special Corn Fertilizer vs. a Fertilizer Containing a Larger 

 Proportion of Potash. Bulletin No. 18, April 1892, page 90. 

 "In view of confirmatory results of the past year's work, as com- 

 pared with that of previous years, I renew with increased confidence 

 the recommendations for the application of fertilizers for corn, made 

 in Bulletin No. 14 of this Station: 



"(a) In breaking up sod-land for corn, particularly that which is 

 in fair condition, but which has been under ordinary farm manage- 

 ment, if fertilizers only are to be used, apply those which are rich in 

 potash. Use materials which will supply 80 to 100 lbs. of actual pot- 

 ash, from 25 to 30 lbs. of phosphoric acid, and from 15 to 20 lbs. of 

 nitrogen per acre. 



"(b) If 'special corn fertilizer' is to be used, apply only a moderate 

 quantity, say 400 to 500 lbs. per acre, and use with^about 125 lbs. of 

 muriate of potash. It is believed this combination will produce as 

 good a crop as 800 to 1,000 lbs. of 'corn fertilizer,' and it will cost 

 considerably less. 



"(c) With ordinary barn-yard manure or stable manure for corn, 

 use potash. I would recommend using about 4 cords of manure and 

 100 lbs. of muriate potash per acre. 



"(g) For fodder or ensilage corn, use either in fertilizers or with 

 manure about one-fourth more potash than above recommended."

 ^ "i. The application of muriate of potash has so invariably in- 

 creased the yield of both stover and grain that the conclusion is irre- 

 sistible that potash should be more abundant in fertilisers for this 

 crop than is usually the ca§c,
