In a laboratory experiment, the effects of adding different biochars to the soil were studied. They were recommended for different purposes based on their properties: soil melioration (from <italic>Amaranthus cruentus</italic> biomass) or carbon sequestration (from<italic> Betula</italic> sp. wood and <italic>Miscanthus sacchariflorus</italic> biomass). Soil respiration (in the absence of vegetative plants) and ecosystem respiration (in the presence of vegetative <italic>M. sacchariflorus</italic> individuals) were assessed. Addition of all biochar varieties resulted in a decrease in CO₂ emission from the soil surface. The CO₂ flux in the absence of living <italic>M. sacchariflorus</italic> plants in the vegetation vessels decreased to a similar extent when adding biochars of all varieties. However, in the presence of living <italic>M. sacchariflorus</italic> plants in the vegetation vessels, differences were found in the intensity of ecosystem respiration in the variants with different biochar varieties. In the presence of <italic>M. sacchariflorus</italic> plants, the highest CO₂ flux was observed with the addition of biochar from <italic>A. cruentus</italic>, and the lowest with the addition of biochar from <italic>Betula </italic>sp. Thus, firstly, the addition of biochar reduced the CO₂ flux from the soil and, secondly, the presence of vegetative plants is a significant factor modifying the differences in respiratory activity between substrates with biochars of different origins.</p></abstract><trans-abstract xml:lang="ru"><p>Целью работы была оценка эмиссии CO₂ из почвы при внесении нескольких разновидностей биоуглей. В лабораторном эксперименте исследовали последствия внесения в почву разных биоуглей, рекомендованных на основе их свойств для разных целей применения: мелиорации почвы (из биомассы <italic>Amaranthus cruentus</italic>) или секвестрации углерода (из древесины <italic>Betula </italic>sp. и биомассы <italic>Miscanthus sacchariflorus</italic>). Оценивали собственно почвенное<italic> </italic>(при отсутствии вегетирующих растений) и экосистемное (в присутствии вегетирующих особей <italic>M. sacchariflorus</italic>) дыхание. Внесение всех разновидностей биоуглей приводило к снижению эмиссии CO₂<sub> </sub>с поверхности почвы. Поток CO₂ при отсутствии в вегетационных сосудах живых растений<italic> M. sacchariflorus</italic> в сходной степени уменьшался при внесении биоуглей всех разновидностей. Однако в присутствии в вегетационных сосудах живых растений<italic> M. sacchariflorus</italic> установлены различия в интенсивности экосистемного дыхания в вариантах с разными разновидностями биоуглей. В присутствии растений <italic>M. sacchariflorus</italic> наибольший поток CO₂ был при внесении биоугля из <italic>A. cruentus</italic>, наименьший – при внесении биоугля из <italic>Betula </italic>sp. Таким образом, во-первых, добавление биоугля снижало поток CO₂<sub> </sub>из почвы и, во-вторых, наличие вегетирующих растений – существенный фактор, модифицирующий различия дыхательной активности между субстратами с биоуглями разного происхождения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>soil respiration</kwd><kwd>ecosystem respiration</kwd><kwd>CO₂ emission</kwd><kwd>biochar</kwd><kwd>carbon sequestration</kwd><kwd>Miscanthus sacchariflorus</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дыхание почвы</kwd><kwd>экосистемное дыхание</kwd><kwd>эмиссия CO₂</kwd><kwd>биоуголь</kwd><kwd>секвестрация углерода</kwd><kwd>Miscanthus sacchariflorus</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерства науки и высшего образования, госзадание</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education, state assignment</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lehmann J., Gaunt J., Rondon M.
