THE MANURING OF THE CANE 107 



the cane being able to grow through the paper, which is made as a bj^-prodnct 

 from superfluous bagasse. 



The nitrifying organism requires a supply of carbohydrate for its best 

 development, and to Ebbels is due the suggestion that molasses may be thus 

 utilized to advantage. 



Tvpes of soil organisms distinct irom the above are those which break 

 down organic carbon compounds. Two classes may be distinguished : — 



1. Those which oxidize organic carbon compounds to carbon dioxide, 

 etc. 



2. Those which reduce organic carbon compounds to methane, etc. 



To the first class probably belong those organisms which enter the sugar- 

 house with the canes, and to which the deterioration of sugar is, at least 

 in part, to be attributed. 



To the fungi, moulds and protozoa ammonification may also be ascribed, 

 though very much less is known of their action than is known of the bacteria. 

 To the last mentioned a harmful action may be due, as there is reason to 

 suppose that tlie}^ may attack and destroy beneficial bacteria.
