XXIV. TABULATED STATEMENT OF FERTILIZING 
COMPOSITION AND VALUATION OF VARIOUS © 
PRODUCTS. 
For convenience as a present and future reference, it is con- 
sidered desirable to present a rather full compilation of the 
analyses of various commercial fertilizing materials and of various 
farm products, giving their fertilizing constituents and valuation. 
There are many other farm products which it would be desirable 
to present in these tables, but their omission is rendered necessary 
by reason of the fact that there have yet been made no complete 
analyses of their fertilizing constituents. This Station purposes 
in the near future to make such analyses as will fill up many of 
these gaps. The analyses presented have been compiled from 
every accessible, reliable source, such as the reports of various 
experiment stations, standard works upon agriculture, and, 
especially, Koenig’s invaluable compilation. 
In making out the following tables, the following prices in cents 
per pound have been fixed in accordance with the trade value of 
the various ingredients adopted for the year 1891: Nitrogen in 
ammonia compounds and in urine of animals, eighteen and one- 
half ; nitrogen in nitrates, fourteen and one-half; organic nitrogen 
in animal matter, as fine ground fish, meat, blood, and solid excre-
