ANNUAL REPORT OF THE 



Off. Doc. 



FERTILIZING CONSTITUENTS OF AMERICAN FEEDING 

 STUFFS AND MANURIAL V.VLUE PER TON. 



Taken from Bulletin No. IG, Prepared by Euos H. Hess, of the State 

 Experiment Station, Pennsylvania. 



In commercial fertilizers there are only three ingredients which 

 a;- e 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 three 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 scien- 

 tifically determined.
