Nature of Acidic Properties of Litter in Bog Birch Forests
Different litter types (strongly decomposed, average decomposed, rhizomatous, peaty, peatified and peaty) characterized by acid and heavily acid reaction of environment, have been formed in the ecological series of bog birch forests beginning from the tall herb to the sphagnum- dead cover forest typ...

| description | Different litter types (strongly decomposed, average decomposed, rhizomatous, peaty, peatified and peaty) characterized by acid and heavily acid reaction of environment, have been formed in the ecological series of bog birch forests beginning from the tall herb to the sphagnum- dead cover forest types. The key factor of differences among sections of this series is moistening. Relationships between total potential acidity of litter and humic fractional and group composition and ash substances, including calcium and iron oxides, were studied using correlation and regression analyses. Fulvoacids of the third fraction, i.e. products of the initial section of detritus humification, were significantly correlated with the total acidity, hence, these compounds may be considered as acidic-forming. Аmong factors which regulate (neutralize) the acidity of environment, the preferential role of calcium has been revealed. It was shown that the most contribution of ash substances, including calcium, to litter enrichment is made by ground vegetation which biochemical selection takes place due to forest type succession. Finally, it is the soil moisture, having an impact on species composition of lower vegetation layers, that is indirectly a prime cause of formation of acidic litter properties. Plant debris of birch forests makes only a basic background |
