Abstract
Studies of living organic matter humification process are essential for understanding of carbon biogeochemical cycle, and considering this, the aim of this study is to analyse relations between properties of the peat, peat humic acids (HAs) and humification degree on example of analysis of two bog profiles in ombrotrophic bogs to identify the links between peat age, decomposition and humification degree, botanical composition and properties of peat humic acids (elemental, functional composition). The found variability of peat properties is much less than the significant differences in properties of peat-forming living matter, thus stressing the dominant impact of humification process on peat properties. Correspondingly composition of peat humic acids are little affected by the differences in properties of precursor living organic material and indicators as decomposition degree, humification degree, humic acid elemental ratio and concentrations of acidic functional groups are best descriptors of changes of organic matter during humification process.
