| 1 | Process of methanogenesis in bogs, and also activity of process in a different environment are shown in the work | 1381 | ||||
| 2 | Analysis experimental data of chemical composition waters bogs ecosystems region Turochak Republic Altay are presented. Keywords: peatbog, peat, water of peats, ash content in peats, chemical composition, humic and fulvic acids | 1697 | ||||
| 3 | The work makes analysis of the regularities of sharing of the separate groups of microorganisms in oligotrophic mires of West Siberia with using cluster-analytical method. The relationships between characteristic, regimes of oligotrophic mires and activity of the biochemical processes are revealed. Keywords: peat mire, peat formation, biochemical processes, microflora, cluster analysis | 1725 | ||||
| 4 | As a result of stationary investigations is established that the peat deposits of mire ecosystems in Siberia of different genesis are biochemically active in the whole profile. Preliminary data reflecting the particular dynamics of biochemical processes, depending on hydrothermal and redox regimes. Is established that, in comparison with Western Siberia, in the gorno-altai mires the processes of anaerobic destruction of cellulose are more expressed. Keywords: mire ecosystems, Western Siberia, Gornyj Altai, biochemical processes, dynamics of microorganisms population | 1316 | ||||
| 5 | It is presented results of research of molecular-mass distribution humic acids in peat soils dranned and used in agricultural production. The influence of the drainages on processes of organic matter transformations in upper layer dranned peat soil-unrepresentative for peat soils oxidation-reduction conditions and raised biological activity that is reflected on structure of humic acids. Keywords: organic matter, drained peat soils, humic acids, factional and group composition of the peat soil, paramagnetic centers, transformation, mineralization | 1446 | ||||
| 6 | There has been tested the biological activity of growth stimulator TTS, obtained from peat. The considerable acceleration of alfalfa (Medicago varia) stalks and roots development in vitro has been shown. The effective concentrations (0.5-1 ml/l) have been determined for using TTS as microclonal propagation stimulator in alfalfa biotechnology. Keywords: growth stimulator, peat, biological activity, tissue culture, microclonal propagation, alfalfa, Medicago varia | 1515 | ||||
| 7 | Microbial communities in virgin and reclaimed fens of Tomsk region were examined in the comparative study. Differences between these peat lands could be found only for a dry season. A number of fungi, evaluated with the plating method, and a share of hydrolytic bacteria were considerably higher in the reclaimed fen. It indicates to the intensification of destruction due to the implemented agricultural afforestation. The differences between fens smooth after long-term rains: fungal and actinomycetal mycelium is fragmentary found in soil layers, number and specific diversity of micromycetes decrease, hydrobionts dominate among bacteria. Thus, though examined fens are hydromorphic soils, weather conditions should be taken into account for soil sampling, because all the microbiologic indicators, which allow characterizing microbial communities of peat soils, sharply vary under the change of dry and moist periods. Keywords: fens, agroforestry, microbial biomass, bacteria, fungi, abundance, taxonomic structure | 1672 | ||||
| 8 | The redox potential of soils seems to be a critical environmental factor because it governs the chemical and biochemical form of many compounds and their availability for plants and soil microorganisms. Dissolved and total organic carbon, total nitrogen and activity of reeducates, xanthine oxidase, phenol oxidase and peroxides were determined in the peat samples. The aim of this study is to compare the activity of enzymes participating in redox potential at two depths of profile Tagan peatland: acrotelm and catotelm. The study has shown the impact of two depths of profile peatland on activities enzymes participating in redox potential like nitrate reductase, xanthine oxidase, phenol oxidase and peroxidase. In soil profiles activity of xanthine oxidase, phenol oxidase and peroxidase increased with the depth in the points 2, 3 and 4 and also xanthine oxidase in point 1. Together with extending into the depth of soil, there was the increase in nitrate reductase activity in points 1, 3 and the decrease in points 2, 4. Keywords: peat soils, activity of nitrate reductase, xanthine oxidase, phenol oxidase and peroxidase | 1580 | ||||
| 9 | The contents of carbon in mire waters changes from 53 before 92.5 mg/l with extreme parameters 27.8–145 mg/l. Mathematical model of carrying out materials is designed for surfaces of watershed basin. The calculations show that long-time average carrying out of carbon with watershed basin at different years forms 4.3–12.8 g/(m2 year), including carbon in humic and fulvic forms, carrying out of which reaches vegetation period 98 % from the general of carbon carrying out at certain months. Keywords: carbon, peat moss bogs, geomorphological profile, carrying out, humic material, chemical composition, mire water, balance, stand; bear, modeling | 1257 | ||||
