Аннотация: Abstract—Assessment of the response of soil microbial communities, performing important ecological andbiospheric functions, to natural or anthropogenic impacts is one of the promising approaches to solve theproblems of stress resilience of ecosystems. A model experiment with soddy-podzolic soil (Eutric Albic Retisol(Abruptic, Loamic)) has shown the inhibitory effect of ammonium and the stimulating effect of lanthanumon methane oxidation by soil microorganisms. The application of ammonium and lanthanum reducedthe taxonomic diversity of the soil bacterial community and changed its structure: the relative content ofgram-positive bacteria of Actinobacteriota and Bacillota phyla decreased, while the portion of gram-negativebacteria of the phylum Pseudomonadota increased. Applied lanthanum causes a significant (by several ordersof magnitude) rise in the relative content of methanotrophs of Methylobacter genus and of obligate methylotrophsof Methylotenera genus in the community. The results of this work may be used to developapproaches for the control of the activity of the soil methane filter and of the accompanying microbiota
