plete decomposition is impossible, because of the 

 absence of air and the accumulation of plant acids 

 which contain antiseptic properties. 



The chemical composition of peaty soils, as given 

 by Conner and Abbot, 1 may be seen in Table 5.

Chemical Analyses of Different Types of Unproductive 

 Black Soils. 



From the table it is evident that the chemical 

 composition is not the same for all peaty soils. This 

 is naturally to be expected, since no two soils are
