MANURES. 



Decomposed vegetables as manure. 



The characteristic distinction between animal and vege- 

 table manures lies in the fact of the former containing a 

 much larger proportion of nitrogen than the latter. 



There are two grounds upon which the relative values of 

 different vegetable substances as manures may be estimated. 

 First) from the quantity and kind of inorganic matter they 

 contain. Second, from the proportion of nitrogen present 

 in each.
