The article discusses the results of hydrochemical and microbiological studies of the waters of the small river Arguzikha, the left-bank tributary of the Amur River. The natural landscapes of the Zeya-Bureya plain, along the territory of which a small river flows, are transformed into agrolandscapes. Organic matter, nitrogen and phosphorus compounds accumulated in the waters of the Arguzikha river. The number of heterotrophic bacteria, the main function of which is the destruction of organic matter, in the summer reached 75 thousand cells / ml, which corresponded to the dirty water quality class. The content of nitrogen compounds in water and the number of ammonium-oxidizing bacteria experienced seasonal dynamics. The obtained results of the study of hydrochemical and microbiological indicators of aquatic ecosystems of the Zeya-Bureya plain are the basis for further study of the technogenic load on small rivers of the agrolandscape.
