“…The CO 2 is fixed by plants and autotrophic micro‐organisms, converted into organic C forms (plant tissues, root exudates, residues, litter, and decaying organic matter) and used as substrate in metabolic processes by heterotrophic organisms (Abatenh et al, 2018). During the mineralization of SOM, part of the organic C is emitted back to the atmosphere as CO 2 because of soil heterotrophic respiration (Gmach et al, 2020; Sokołowska et al, 2022), or as CH 4 because of anaerobic methanogenesis, although CH 4 may also be assimilated by methanotrophic biomass (Cezar et al, 2021; Mills et al, 2013). Soil physical and chemical conditions drive microbial activity, and, through that, influence the forest fluxes of GHGs.…”

“…It has also been shown that soil drought causes water stress, which can impair the microbial activity and physiological capacity of methanotrophic bacteria (Feng et al, 2020; Schnell & King, 1996; Striegl et al, 1992). The activity of methanotrophic bacteria is important, not only because of the CH 4 they consume in soils where O 2 is readily available, but also because the CH 4 is oxidized to intermediate metabolites and the derived C is incorporated into their biomass, or converted to CO 2 , or released as C compounds to heterotrophic microorganisms, completing the C biogeocycle (Abatenh et al, 2018; Cezar et al, 2021; Mills et al, 2013; Stock et al, 2013).…”

“…Soil CO 2 emission occurs because of microbial heterotrophic respiration resulting in mineralization of soil organic matter (SOM) (Abatenh et al, 2018; Gmach et al, 2020; Peterson et al, 2021; Sokołowska et al, 2022; Vicentini et al, 2019; Wanyama et al, 2019). Soil CH 4 is produced by methanogenic archaea under anaerobic conditions, and it is consumed by methanotrophic bacteria under aerobic conditions (Cezar et al, 2021; Mills et al, 2013). Soil N 2 O is emitted because of bacterial nitrification and denitrification processes (Monteiro et al, 2020; Veloso et al, 2018).…”

“…Soil N 2 O is emitted because of bacterial nitrification and denitrification processes (Monteiro et al, 2020; Veloso et al, 2018). All these processes are very dynamic because the soil microbial, diversity, biomass and activity are influenced by soil ecosystem, vegetation cover and physical and chemical attributes, as well as by SOM composition, and climatic conditions (Ball, 2013; Cezar et al, 2021; Kaschuk et al, 2010; Peterson et al, 2021).…”

Forest soils can be sources or sinks of greenhouse gases (GHGs) depending on soil attributes that affect biomass and activity of soil micro-organisms involved in GHGs fluxes. In this work, we tested the hypothesis that soil physical, chemical and microbiological attributes, under different forests ecosystems, affect the soil GHGs [nitrous oxide (N 2 O), carbon dioxide (CO 2 ) and methane (CH 4 )] fluxes.The study was carried out in two locations in southern Brazil in 2019, with three experimental plots of 900 m 2 in native forests of the Atlantic Forest biome and in loblolly pine (Pinus taeda) plantations. Air samples released from the soil surface were analysed for concentration and flux of CO 2 , N 2 O and CH 4 . Soil samples were analysed for chemical attributes, density (Ds), soil microporosity (MiPs), soil macroporosity (MaPs), total porosity (TP), water-filled pore space (WFPS), microbial biomass carbon (MB-C), basal respiration (BR), microbial (qMic) and metabolic (qCO 2 ) quotient and activities of soil urease and βglucosidase enzymes. The seasons influenced the CO 2 and N 2 O emissions, probably because of the changes in seasonal conditions. However, native forests consumed more CH 4 than pine plantations. Meanwhile, the native forests presented soils with lower Ds (average 21.5% lower), more TP (average 12.5% higher) and more moisture (average 33% higher), which improved the microbiological attributes of the soil (20% to 60% more MB-C, 67% higher urease activity and 30% higher βglucosidase activity) compared with pine plantations. Native forests contributed more intensely to CH 4 consumption than pine plantations because they present better physical, chemical and microbiological soil conditions. Therefore, it is possible that forestry practices that improve soil physical attributes are likely to contribute to increase CH 4 consumption, and to reduce GHGs emissions in forest ecosystems.

“…Nevertheless, belowground biodiversity in soybean fields in Brazil is still poorly described. Studies have investigated the bacterial community in soybean fields (CEZAR et al, 2021;LEITE et al, 2021;BARRETO, 2021), but the nematode community has been overlooked and the relationship between bacteria and nematodes needs to be better understood.…”

Background and Aims Crop rotation systems and rhizobial inoculation are strategies to increase yield through organic matter addition and modulation of microbial diversity, yet the extent to which these agricultural practices change soil Bradyrhizobium populations, soybean grain yield and economic bene ts to farmers are unclear. Thus, this study aimed to evaluate the interaction between crop rotation and inoculation of soybean (Glycine max) cultivated in two contrasting soils (clayey and sandy soil) on biological nitrogen xation (BNF) components, grain yields and pro ts.Methods Field experiments with a three-year crop rotation system were carried out to compare effects of inoculation soil chemical attributes, the of bradyrhizobia most probable number (MPN) and diversity, soybean nodulation, grain yield and economic value.Results The crop management system did not affect the soil MPN of bradyrhizobia, which was altered by the soil sampling time, with higher values during the postharvest period for the summer crops. In clayey soil, soybean nodulation was in uenced by crop rotation. The grain yield of inoculated soybean in clayey soil was higher than that in sandy soil. ConclusionThe soybean response to inoculation is in uenced by cropping history. Crop rotation and inoculation of soybean is a strategy for improving BNF components, grain yields and pro ts. Over time, diversi ed production systems with crop rotation and inoculation with nitrogen-xing bacteria will make great contributions to environmental and economic sustainability.nitrogen contributions to the succeeding cereals in a crop rotation ranged from 38 to 126 kg N ha − 1 (Sanginga et al. 2003). In addition, in a study with small farmers in Malawi, the crop rotation between maize and soybean had a contribution from BNF of 63 kg N ha − 1 (van Vugt et al. 2018). Long-term effects are observed wherein the overall crop diversity and species composition of a rotation impact crop yield, fertility and microbial communities. Rotations with more than two crops grown in sequence result in greater maize and soybean yield, microbial diversity, and altered microbial activity and community structure (Benitez et al. 2021), microbial assembly and enzyme stoichiometry in soil cultivated with double-cropping system of wheat/rice (Xie et al. 2022), and higher levels of corn N uptake (Bowles et al. 2022).Considering that microorganisms are swayed by soil environmental factors, we hypothesized that in the short-term soil texture and crop rotation systems would lead to differences in soil diversity of bradyrhizobial populations due physicochemical conditions. Specially, we expected that soybean seed inoculation with selected Bradyrhizobium sp. strains in crop rotation-managed eld would be associated with increasing BNF components in grain yields. Our goals were to evaluate the impacts of crop rotation and soybean inoculation on the abundance of the bradyrhizobia in the soil, diversity of isolates from soybean nodules and its effects on BNF components, grain production and econom...
