The trends of enzyme activities and litter chemistry after abandonment of arable soil and succession of natural vegetation were studied in a deciduous forest zone (Moscow region, Russia). The Luvic Phaeozem chronosequence included an arable field, 3 fields with increasing abandonment periods (7, 11, 35 years), and the soil under natural forest as a...

The decomposition rate of four species of peat-forming plants typical of bog phytocenoses in the southern taiga subzone of Western Siberia—Sphagnum fuscum, Chamaedaphne calyculata, Eriophorum vaginatum, and Sphagnum angustifolium—was determined in the 3-yr field experiment. The research was performed by the method of partially isolated samples on t...
Article
Full-text available
After abandonment of agricultural lands (ongoing on 220 Mio ha worldwide), degraded arable soils undergo self‐restoration and development towards natural ecosystems. We studied the linkage between microbial properties and density fractions of soil organic matter (SOM) during post‐agricultural restoration of former arable Phaeozems and Chernozems. T...

Tree bark represents an important but rather poorly investigated component of coarse woody debris (CWD). We applied the component integration method to partition CO2 flux from the surface of CWD into tree bark respiration and exposed wood surface respiration. Twelve large fragments of spruce (Picea abies (L). Karst), birch (Betula pubescens Ehrh an...
Chapter
Fast growth of urban population during the last century led to massive abandonment of arable lands near big cities due to the outflow of rural population. After withdrawal, former arable lands undergo a process of self-restoration, and there are some periods of natural succession of vegetation and soils. This study was aimed to estimate the changes...

Article
The seasonal snowpack plays an important role in the ecosystem–atmosphere CO2 exchange, especially in temperate continental regions, preventing frost penetration into the soil and thus impacting the CO2 efflux from soils. Due to current climate changes, the snow cover period in many Russian regions has become shorter because of the later onset of s...

The collapse of Soviet Union in early 1990s led to abandonment of large area of arable land which is assumed to act as a carbon (C) sink. We studied the ability of two dynamic soil C models (Yasso07 and RothC) to predict changes in soil C content after cropland abandonment. The performance of the models was compared using the results of a long-term...
Article
The collapse of collective farming in Russia after 1990 and the subsequent economic crisis led to the abandonment of more than 45 million ha of arable lands (23% of the agricultural area). This was the most widespread and abrupt land use change (LUC) in the 20(th) century in the northern hemisphere. The withdrawal of land area from cultivation led...

Land use system in Russia has been significantly changed since 1990. More than quarter of croplands (about 34 M ha) including soils of southern regions (Chernozems. Kastanozems) was abandoned. The abandonment of cultivated lands and successive establishment of natural vegetation led to carbon (C) accumulation in soil, qualitative changes in organic...
Article
Full-text available
Experimental studies and the analysis of published data have shown that carbon reserves in soils generally increase upon soil exclusion from agricultural use. The rate of carbon accumulation in the abandoned soils depends on the soil type, the time elapsed since the soil abandoning (the restoration period), and the thickness of the layer for which...
Article
Abandonment of cultivated lands leads to vegetation succession, restoring of soils, and is ac-companied by changes in organic carbon pools and microbial community. This study was aimed to quantify the different carbon organic pools (total, labile, recalcitrant, and microbial) in former croplands depending on the period of abandonment (restoration)....

Article
Full-text available
The repeated freeze-thaw events during cold season, freezing of soils in autumn and thawing in spring are typical for the tundra, boreal, and temperate soils. The thawing of soils during winter-summer transitions induces the release of decomposable organic carbon and acceleration of soil respiration. The winter-spring fluxes of CO2 from permanently...

Article
Soils represent the major source of the atmospheric greenhouse gas nitrous oxide (N2O) and there is a need to better constrain the total global flux and the relative contribution of the microbial source processes. The aim of our study was to evaluate isotopomer analysis of N2O (intramolecular distribution of 15N) as well as conventional nitrogen an...
Article
A database on the respiration of Russian soils was developed. Its analysis, together with the use of a model to assess the annual fluxes of CO2 from soils, made it possible to refine the estimates of the total, microbial (heterotrophic), and root respiration for the territory of Russia.

Absatract Carbon balance on Russian territory is mainly governed by a ratio of carbon fluxes in the forest zone which occupies about 3/4 of total area (1187 million ha). The net carbon exchange of terrestrial ecosystems is the result of delicate balance between the uptake (photosynthesis) and loss (soil respiration). A special Soil Respiration Data...
Article
The annual CO2 fluxes from soils of different ecosystems of the southern Moscow region averaged over a 5-year cycle were estimated from long-term year-round field observations. They varied from 352 ± 66 to 817 ± 105 g C/m2 per year. The interannual variation of the total annual CO2 fluxes from soils of different ecosystems was 33% on average; the h...
Article
Sharp rises in the respiration activity of soils have been registered during soil thawing and immediately after it. Depending on the water content of soils and the character of their use (forest vegetation versus cropland), the rate of soil respiration upon thawing reached 19-70% of the rate of soil respiration at 10°C. It is argued that soil respi...
Article
abstractAnnual and seasonal characteristics of CO2 emission from five different ecosystems were studied in situ (Russia, Moscow Region) from November 1997 through October 2000. The annual behaviour of the soil respiration rate is influenced by weather conditions during a particular year. Annual CO2 fluxes from the soils depend on land use of the so...

Root respiration and its contribution to the annual CO2 emission from gray forest and soddy-podzolic soils under plowland and undisturbed vegetation have been studied in field experiments. The root respiration intensity under undisturbed vegetation depends on the contents of phytodetritus in the samples of soil and roots. Therefore, a separate asse...

An assessment of the carbon dioxide efflux from soils into the atmosphere during frostless and winter periods has been performed. It is shown that the emission of CO2 during the growing season constitutes 53-83% of the annual efflux. A database on soil respiration in the taiga zones of Russia has been developed. On this basis, a detailed statistica...
