    Sorption properties for black carbon (wood char) after long term exposure in soils
[] / C. -H. Cheng [et al.] // Org. Geochem. - 2014. - Vol. 70. - P53-61, DOI 10.1016/j.orggeochem.2014.02.013 . - ISSN 0146-6380
Аннотация: Amending soil with black carbon (BC) can change the sorption properties of the soil. However, there is some concern based on studies that deal with newly produced BC and barely consider the possible changes in sorption properties for BC after being amended in soil. This study uses newly produced BC and historical BC samples, along with soils containing high levels of historical BC and adjacent soils without visible BC, to compare their diuron, atrazine and Cu2+ sorption properties. Compared with newly produced BC, historical BC exhibited reduced (56-91%) sorption capacity for diuron and atrazine but 2-5 times enhanced sorption capacity of Cu2+. These changes in sorption properties can be interpreted via the formation of surface functional groups in BC. Whereas the sorption capacity for diuron and atrazine was reduced with historical BC, the sorption capacity of BC-containing soils was higher than for the adjacent soils, indicating that BC possessed stronger sorption capacity than non-BC material. A biological assay revealed reduced herbicide efficiency for the newly produced BC, and even the historical BC still exerted an influence on reducing herbicide efficiency. Along with its recalcitrance in environments, BC has a significant long term effect on the toxicity of contaminants and soil fertility. © 2014 Elsevier Ltd.

Аннотация: To separate soil respiration (SR) to microbial and root component in related to N input difference, we established trenching plot, and measured SR at N fertilization plots (urea of 60 kg N ha–1 y–1) and controls in a larch forest in central Siberia. Soil temperature and moisture were not different among the plots. In contrast, SR (unit: mg CO2-C m–2 h–1) in July was higher in the fertilization plots (167 ± 55) than in control (106 ± 27), and decreased by 21 and 39 % after root cutting in control and N fertilization plots, respectively. We found N fertilization increased root respiration rather than microbial respiration.

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.

    Биоиндикация состояния темно-серой почвы в сосняках Красноярской лесостепи при антропогенном воздействии
[Текст] / И. Д. Гродницкая, В. А. Сенашова, Г. И. Антонов, Г. Г. Полякова [и др.] // Почвоведение. - 2023. - № 9. - С. 1173-1189, DOI 10.31857/S0032180X23600415 . - ISSN 0032-180X
Аннотация: Биологическую активность темно-серой почвы исследовали в 100-летнем сосняке разнотравно-зеленомошном Погорельского бора Красноярской лесостепи. В 2017 г. в сосняке были проведены выборочные рубки, а в мае 2022 г. произошел сильный пожар. Для улучшения лесовосстановления и повышения биологической продуктивности почвы на вырубленные и горевшие участки вносили биоудобрение на основе опилочно-почвенного субстата с микопродуктом и мочевиной (ОПСМ + М). На экспериментальных участках (пасека, волок, фон) проводили ежегодный учет самосева сосны. Биоиндикацию состояния почвы оценивали на основании общей численности и соотношения долей эколого-трофических групп микроорганизмов, активности ферментов, содержания микробной биомассы, интенсивности базального дыхания и удельного дыхания микробной биомассы. Внесение биоудобрения на вырубленные участки способствовало подщелачиванию почвы на 0.2–0.4 ед., сохранению влажности, увеличению содержания азота (на 5–14%) и микробной биомассы (в 1.2–1.6 раза) по сравнению с контрольными вариантами. Воздействие биоудобрений на всхожесть и рост самосева сосны отмечено на второй год после внесения: на опытных участках самосева было в 4–6 раз больше, чем на контрольных. Поступление в почву обгоревших растительных остатков, углей и золы в первую неделю после пожара привело к активизации микроорганизмов-карботрофов, которые увеличивали общую численность микроорганизмов, микробную биомассу, активность уреазы и инвертазы. Однако к концу вегетационного периода отмечали снижение микробиологической активности, что указывало на постпирогенную депрессию микробоценозов. Внесение биоудобрения на сгоревшую поверхность участков нивелировало влияние пирогенного воздействия и стимулировало образование всходов сосны обыкновенной, количество которых было достоверно больше, чем на контрольных участках. Установлено, что универсальными биоиндикаторами, адекватно отражающими состояние почвы после всех антропогенных воздействий, были микробная биомасса, удельное микробное дыхание, ферментативная активность и общая численность микроорганизмов. Специфической биоиндикацией состояния почвы после пожара являлось увеличение доли бактерий Serratia plymuthica, Bacillus mycoides и грибов родов Trichoderma, Penicillium и Mortierela.
3The biological activity of dark gray soil was studied in a 100-year-old pine forb-green-moss forest of the Pogorelsky pine forest of the Krasnoyarsk forest-steppe. In 2017, selective cuttings were carried out in the pine forest, and in May 2022 there was a strong fire. To improve reforestation and increase the biological productivity of the soil, bio-fertilizer based on sawdust-soil substrate with the addition of urea and mycoproduct (SSSU + M) was applied to cut and burned areas. On the experimental plots (Paseka, Volok, Fon), an annual count of self-seeding of pine was carried out. Bioindication of the soil condition was assessed based on the total number and ratio of ecological-trophic groups of microorganisms, enzyme activity, microbial biomass content, intensity of basal respiration and specific respiration of microbial biomass. The application of biofertilizer to the cut areas alkalized the soil by 0.2–0.4 units, retained moisture, increased the content of nitrogen (by 5–14%) and microbial biomass (by 1.2–1.6 times), compared with the control options. The impact of biofertilizers on the germination and growth of self-seeding of pine was noted in the second year after application – in the experimental plots of self-seeding it was 4–6 times greater than in the control ones. The entry of burnt plant residues, coals and ash into the soil in the first week after the fire led to an increase in some microbiological indicators, the activity of urease and invertase, and the activation of carbotrophic microorganisms. However, by the end of the growing season, a decrease in microbiological activity was noted, which indicated a post-pyrogenic depression of microbocenoses. The introduction of biofertilizer on the burnt surface of the plots leveled the effect of pyrogenic effects and stimulated the formation of shoots of scots pine, the number of which was significantly higher than in the control plots. It was found that the universal bioindicators that adequately reflect the state of the soil after all anthropogenic impacts were microbial biomass, specific microbial respiration, enzymatic activity and the total number of microorganisms. A specific bioindication of the soil condition after the fire was an increase in the proportion of bacteria Serratia plymuthica, Bacillus mycoides and fungi of the genera Trichoderma, Penicillium and Mortierela
