“…Temperature dependence of transplanted soils CO2 efflux had the highest value (R 2 = 0.8) in the first two years due to maximum contrast of temperature conditions between sites and decreased in the last two years. On the contrary, the temperature sensitivity of transplanted soils' CO2 efflux showed a high value during most years (Q10 = 3-6), thus indicating the increased rate of organic matter decomposition in peatland soils of permafrost area for an extended period (4 years) [46].…”

The review article discusses the application of biogeochemical technologies aimed at restoring biogeochemical cycles in agroecosystems, primarily in the microbial link regulating CO2 flows. The factors of management this microbial link when applying mineral and organic fertilizers are shown. The processes of mineralization of soil organic matter and methods of controlling soil's conjugate carbon- and nitrogen-mineralizing ability are considered. The changes in the productivity of agricultural ecosystems under conditions of increasing concentration of carbon dioxide in the atmosphere and soil air are considered. Various agrotechnological techniques are considered, including using zero tillage, organic fertilizers of various nature, and various meliorants, including phosphogypsum. Examples of recultivation of disturbed and polluted soils, waterlogged and/or over-drained soils are given and the impact on CO2 fluxes is estimated. Based on numerous data, it is concluded that agroecosystems in most cases are a net source of CO2, and sequestration occurs only when agricultural land is transferred to fallow lands and at afforestation. At the same time, techniques aimed at reducing CO2 fluxes using fertilizers in the "production–application" cycle are evaluated. A set of biogeochemical technologies aimed at assessing and stabilizing the microbial link of the biogeochemical cycle in agroecosystems is presented. Examples of the use of these technologies for regulating CO2 emissions in agroecosystems are given. Using one of the biogeochemical technologies, the almost 5-fold decrease in the rate of CO2 flows during the reclamation of disturbed tundra ecosystems is shown. Adopting agricultural low carbon technologies (ALCTs) cannot yet testify to their applicability to ensure both food and environmental safety. It is necessary to further develop and use biogeochemical technologies to restore biogeochemical cycles in agroecosystems, primarily in the microbial link regulating CO2 flows.

Dynamics of soil CO2 emission, temperature, and moisture were studied during the vegetation season (from May to October) in 2021 and 2022 in the residential areas of Murmansk and Apatity cities (Murmansk oblast) in comparison with natural areas. The mean emissions from urban soils were 5–7 g C/(m2 day) in summer and 1–2 g C/(m2 day) in spring and fall. Temperature was the main abiogenic factor that determined the seasonal dynamics of soil respiration (R2 from 0.4 to 0.7, p < 0.05; Q10 temperature coefficient up to 2.5), while excess moisture had a limiting effect, especially in the natural areas. The heterogeneity of hydrothermal conditions and the content of biophilic elements determined the differences in the mean CO2 emission between natural and urban soils. For the natural soils, the mean temperature was lower and the moisture content was higher than for urban areas, which determined the lowest emission values. Among urban sites, higher CO2 emissions were found for tree and shrub vegetation sites.
