The Difference

In this paper we consider plant (geobotanical) indicators of soils, occurring in regressive bogs in the north taiga subzone of West Siberia. The specificity of regressive bogs is the difference between current vegetation and botanical composition of the peat surface horizon, which complicates their biological diagnostics. The data on peat botanical composition, degree of decomposition and thickness are presented. Destructive oligotrophic peat soils, the allocation of which is provided in the actual Russian soil classification at the level of subtype, occur in palsa bogs under shrub-lichen vegetation. Their indicators include lichens: Cladonia stellaris, C. rangiferina, C. stygia, C. arbuscula, C. mitis, Alectoria ochroleuca, Сetraria islandica, C. laevigata, Flavocetraria cucullata, F. nivalis, Govardia nigricans. A new subtype - peat oligotrophic regressive soils - which occurs in non-freezing bog is suggested. The indicators of this soil subtype in pine-shrub-sphagnum bogs are lichens Cladonia cenotea, C. chlorophaea, C. coniocraea, C. cornuta, C. crispata, C. deformis, C. gracilis, C. fimbriata, C. mitis, C. ochrochlora, C. pleurota, C. polydactyla, C. pyxidata, C. rangiferina, C. stellaris, C. subulata, C. sulphurina and liverwort Mylia anomala . The indicators of regressive soils in bog hollows are mainly liverwort Cladopodiella fluitans , mosses Warnstorfia fluitans , W. exannulata , and lichen Cetrariella delisei .

New Interpretation

A digital version of the soil map of the Russian Federation, scale 1 : 2.5 M, is being prepared based on the analysis of the attributes of polygons with peat soils in the West-Siberian taiga and sub-taiga zones. The correction was perfomed in 795 polygons (with the total area of 179 483 km2) out of 1 711 polygons considered (with the total area of 262 204 km2). The currently formulated idea of the dominance of oligotrophic bogs in the West Siberian taiga region of mires served as the basis for suggestion to replace the mesotrophic peat soils by oligotrophic ones in 598 polygons of the total area of 87 250 km2. Similarly, the polygons of microcatenas comprising oligotrophic and mesotrophic peat soils (57 polygons, total area of 38 405 km2) were modified: only oligotrophic peat soils were considered to be the dominant ones there. At the same time, a number of polygons with prevailing oligotrophic soils, confined mainly to the sub-taiga zone were proposed to be replaced by polygons with mesotrophic peat soils. The thermokarst pools in ridge-hollow mire complexes that were shown on the soil map of Russia beyond the permafrost zone were eliminated from the map database; the mapping of destructive peat soils was rearranged in accordance with the new interpretation of this taxon in the Russian soil classification. This work should improve the quality of research in the field of assessing the resource potential of peat soils in West Siberia.

Remediation of oil-polluted peat soils is very important for Western Siberia. The necessary condition for successful of it is taking into consideration of ecological, climatic and hydrological condition of this region. The general parameters of environments here are high flooding, regime of temperature, short vegetation period, and specific properties of peat.

The results of studies on the influence of agrotechnological techniques on the productivity of alfalfa (Medicago sativa), cultivation on agro-peat soils in the south of Belarus were presented. It was established that the yield of green mass on average over 4 years of life was 393.6–517.9 c / ha when sown under cover and 494.3–629.8 centners ha-1 with coverless sowing. Productivity — 56.5–75.1 and 69.5–89.7 centners ha-1, respectively. A positive correlation between the increase in the yield and productivity of the grass stand with an rise in the seeding rate and doses of fertilizers applied was noted.

Optimal Set

The data on the yield of lucerne (Medicago falcate) when cultivated on agro-peat soils in the conditions of southern Belarus was presented. It has been established that the yield of green mass in 4 years of life averaged 422.9 centner per ha at sowing under cover and 472.4 centner per ha at bloodless sowing. Productivity — 57.7 and 68.2 centner feed units ha–1 respectively. A small level of response to the application of various technological techniques was noted.
