Forms of biogenic silica in meadow soils of the Middle Amur lowland

With the use of modern experimental techniques, the authors have obtained new information about the presence of biogenic silica forms in the meadow soil of the Middle Amur Lowland, represented by remnants of phytoliths and shells of diatoms. It is revealed the features of phytoliths and diatoms redistribution in the soil body, and their belonging to a certain biocenosis. Meadow phytoliths forms prevail in the soil profile. Diatoms are represented by small celled species (supposedly, spores of Cyclotella sp.), as well as by large forms of the Nitzchia and Eunotia genus.
