ANNUAL REPORT OF THE 



Off. Doc. 



FERTILIZIMJ CONSTITUENTS OF AMERICAN FEEDING 

 STUFFS AND MANURIAL VALUE PER TON. 



Taken from Bulletin No. IG, Prepared by Enos n. Hess, of the State 

 Experiment Station, Pennsylvania. 



In commercial fertilizers there are only three ingredients which 

 are assumed to have any practical value, namely: Nitrogen, phos- 

 phoric acid and potash. The foods used in feeding dairy cattle con- 

 tain more or less of these throe ingredients, and, therefore, have a 

 fertilizing value equal to the amount of nitrogen, phosphoric acid 

 and potash they contain. The nitrogen is valued at twelve cents per 

 pound, the phosphoric acid at four cents and potash at five cents 

 per pound. No allowance is made for the value of the humus, which 

 has some value, but as to how much it has, will have to be left to 

 the judgment of the reader, for as yet it has not been scientifically 

 determined.
