The change elemental composition of Sphagnum species phytomass in peat formation process // Tomsk State Pedagogical University Bulletin. 2008. Issue 4 (78). P. 30-34

The peat formation is the permanent process of mire phytomass transformation to a peat. This transformation has some stages. In an initial stage new phytomass is produced, the next phase is the dying off of the living phytomass, the third stage is the dead phytomass transformation into a mire litter and the last one is a peat formation from a litter. The quantitative elemental composition of the organic matter at the different stages of this process is distinctive. We compared the elemental composition of living and dead phytomass, the litter and the peat for two mires and three Sphagnum species. It has been shown that the change pattern of chemical composition of organic matter seems to be identical
