A comprehensive study of the impact of Solidago canadensis on the soil ecosystem using the example of monodominant communities of this species located on the exposition plot ‘Steppes of Ukraine’ of the M.M. Gryshko National Botanical Garden of the NAS of Ukraine (Kyiv) is presented. The research was conducted during the growing seasons of 2023–2024. The content of macro- and microelements, secondary metabolites in leaves and soil, allelopathic activity, organic and mineral carbon content, and laccase activity were assessed, and the functional structure of soil microbial communities was determined.It has been established that S. canadensis actively regulates the absorption of nutrients, which serves as an adaptive mechanism to environmental changes. The capacity of S. canadensis to reduce soil contamination with toxic metals such as Mn, Zn, Co, Cr, Fe, Pb, and Ti has been shown. For Mn and Zn, S. canadensis acts as a phytoextractor, and for Co, Cr, Fe, Pb, and Ti, it acts as a phytostabilizer.Significant phenological fluctuations in allelopathic activity, the content of biologically active secondary metabolites, and the functional structure of the rhizosphere microbiota in S. canadensis have been shown. The successful spread of S. canadensis outside its natural range may be associated with the ability of this plant to produce and release into the environment a number of secondary metabolites of phenols, terpenoids, saponins, etc., which are responsible for its high resistance to abiotic and biotic stress factors, allelopathic activity, inhibit the development of harmful bacteria and stimulate the development of actinomycetes, which participate in the restoration of soil fertility and are antagonists of phytopathogens.
