The article presents the analysis of the microbiomorphic soil profile of the swampy meadow. Phytoliths, spicules of sponges and Rhizopoda shells are abundant in the soil. There are spores of fungus and mosses, as well as zoogenic material. The change in the natural conditions of the object during the second half of the holocene was reconstructed based on the obtained data. Differences in the content of microbiomorphs in different horizons of the soil profile of the swampy meadow correspond to the general regional and local processes of climate and vegetation dynamics in Northern Kulunda and adjacent territories.
