Аннотация: Vertical and horizontal distributions of soil organic carbon, potential microbial activity and basic soil properties were studied in a boreal mixed forest (Central Forest Reserve, TVER region) to elucidate whether the soil CO(2)-efflux is related to basic soil properties that affect the C pool and activity. Soil cores (0-100 cm depth) were taken from two transects every 50 meters (44 points) immediately after completion of soil CO(2)-efflux measurements. Soil was separated into layers and moisture, bulk density, root density and bacterial counts were determined within one day after soil was taken. Microbial respiration, biomass, CN contents and pH were measured within few months. The variability in the soil CO(2)-efflux and microbial activity was mainly explained by soil bulk density. Results further indicate that laboratory measurements of microbial respiration can represent heterotrophic soil respiration of a distinctive ecosystem in natural conditions, if microbial respiration is measured after the effect of soil handling disappears.

Аннотация: The effects of cutting on the ecological conditions and soil respiration in larch forests of Japan were studied. The cutting was found to significantly change the soil surface, resulting in the high spatial and temporal variation of the hydrothermal conditions and soil respiration. The influence of a stand's thinning on the environment and soil respiration is considered using the example of the thinning of a ripening larch stand in the Tomakomai National Forest (Hokkaido Island, Japan). The changes in the hydrothermal conditions (the temperature and moisture of the mineral soil layers and litter) and some other factors (the root and litter density and the C/N ratio) after the thinning of the stands and their influence on the soil respiration were studied. The soil respiration in the thinned forest site did not differ from that on the control plot, whereas the soil temperature was much higher in the former. The moisture of the soil mineral layers and the litter was the same. Despite the latter fact, no significant relationships between the soil respiration and its temperature and moisture were found. In the area covered with the thinned forest, the water content of the litter turned out to be the main microclimatic factor affecting the soil respiration. There, the fine roots and litter density were 18 and 15 % less, respectively. The thinning of the stand induced high variation of the soil respiration and temperature, as well as of the fine roots and the litter density. On the whole, the soil respiration in the larch forest studied in Japan was determined by the litter stock and the C to N ratio.

Аннотация: The estimates of the carbon pool in the organic matter of gray soils of the southern taiga, the intensity of destruction of its components, and participation of the latter in the formation of the mineralized carbon flux to the atmosphere are presented for different stages of succession of deciduous (birch) and coniferous (fir) forests. The carbon pool varies from 139.7 to 292.7 t/ha. It is distributed between phytodetritus, mobile and stabile humus (32, 19, and 49%, respectively). The intensity of the mineralization carbon flux to the atmosphere amounts to 3.93-4.13 t C per year. Phytodetritus plays the main role in the formation of this flux. In the soils under the forests studied, 4-6% of the carbon flux are formed owing to mineralization of the newly formed soil humus. In birch forests, 2-6% (0.1-0.2% of the humus pool in the 0-20-cm layer) is the contribution to the flux due to mineralization of soil humus. In fir forests, the mineralized humus is compensated by humus substances synthesized in the process of humification during phytodetritus decomposition.

Аннотация: The results of a field experiment for studying the seasonal dynamics of the CO2 (R-all) emitted from the overburden and enclosing rocks of a coal mine are presented as an integral index of their biological activity. The mean rate of the CO2 emission from the control substrate was 1.2 g C/m(2) per 24 h. The intensity of R-all for the variant with the application of mineral and complex fertilizers, along with a microbiological preparation, was higher by 28 and 34%, respectively. In the same variants, the R-all values little changed during the whole growing period. The measurements of the potential respiration of the rock mixture in the laboratory showed that a significant part of the CO2 flux was formed at the expense of carbon dioxide of abiotic origin. The values of the CO2 emission are concluded to be overestimated as compared to those for the real level of the biological activity of the substrates studied.

Аннотация: This study aimed to better understand the stabilisation of rice rhizodeposition in paddy soil under the interactive effects of different N fertilisation and water regimes. We continuously labelled rice ('Zhongzao 39') with (CO2)-C-13 under a combination of different water regimes (alternating flooding-drying vs. continuous flooding) and N addition (250 mg N kg(-1) urea vs. no addition) and then followed C-13 incorporation into plant parts as well as soil fractions. N addition increased rice shoot biomass, rhizodeposition, and formation of C-13 (new plant-derived C) in the rhizosphere soils under both water regimes. By day 22, the interaction of alternating flooding-drying and N fertilisation significantly increased shoot and root C-13 allocations by 17 and 22%, respectively, over the continuous flooding condition. The interaction effect also led to a 46% higher C-13 allocation to the rhizosphere soil. Alone, alternating water management increased C-13 deposition by 43%. In contrast, N addition increased C-13 deposition in rhizosphere soil macroaggregates under both water regimes, but did not foster macroaggregation itself. N treatment also increased C-13 deposition and percentage in microaggregates and in the silt and clay-size fractions of the rhizosphere soil, a pattern that was higher under the alternating condition. Overall, our data indicated that combined N application and a flooding-drying treatment stabilised rhizodeposited C in soil more effectively than other tested conditions. Thus, they are desirable practices for improving rice cropping, capable of reducing cost, increasing water use efficiency, and raising C sequestration.

Аннотация: As global temperatures continue to rise, a key uncertainty of climate projections is the microbial decomposition of vast organic carbon stocks in thawing permafrost soils. Decomposition rates can accelerate up to fourfold in the presence of plant roots, and this mechanism-termed the rhizosphere priming effect-may be especially relevant to thawing permafrost soils as rising temperatures also stimulate plant productivity in the Arctic. However, priming is currently not explicitly included in any model projections of future carbon losses from the permafrost area. Here, we combine high-resolution spatial and depth-resolved datasets of key plant and permafrost properties with empirical relationships of priming effects from living plants on microbial respiration. We show that rhizosphere priming amplifies overall soil respiration in permafrost-affected ecosystems by similar to 12%, which translates to a priming-induced absolute loss of similar to 40 Pg soil carbon from the northern permafrost area by 2100. Our findings highlight the need to include fine-scale ecological interactions in order to accurately predict large-scale greenhouse gas emissions, and suggest even tighter restrictions on the estimated 200 Pg anthropogenic carbon emission budget to keep global warming below 1.5 degrees C.
