from the Nitrate, the timothy was more than able to hold p oodfor 

 its own and thus to make what the market calls a finer, better 

 hay; and since the market demands timothy and pays for it, 8 3 

 the farmer who sells hay is wise if he meets the demand.

Financial Profit from Use of Nitrate. 



How It Pays. 



Frequently more plant food is paid for 

 and put on the land than the crop can 

 possibly use, the excess being entirely thrown away, or, at 

 best, saved to benefit some subsequent crop. This was far 

 from the case in these trials. Indeed, it was found by analysis 

 of the hay that more potash was removed by the crops of the 

 first two years than had been added in the muriate used, con- 

 sequently the amount applied upon each plat was increased in 

 1901 and in 1902. The Nitrogen requirement of the crops 

 was found to be slightly less than was supplied in 450 pounds 

 of Nitrate and the amount was reduced to 400 pounds in 

 1901, and to 415 pounds in 1902. The Nitrate on the second 

 plat was also reduced in proportion. The phosphoric acid, 

 however, was probably in considerable excess, since liming sets 

 free phosphoric acid already in the soil and so lessens the ap- 

 parent financial profit; but not to an excessive degree.
