The destruction of plant residues of floodplain vegetation in the aquatic environment was studied. The objects of study were three herbsspecies dominant in the Ob floodplain: Inula salicina, Calamagrostis purpurea and Carex atherodes. Dissolved organic matter (DOM), which plays a significant role in the aqueous environment, was studied carefully. As a result of the work, there was revealed the species specificity in the leaching processes of major elements,trace elements and organic matterfrom herbs. It has been established that the motley grasses samples are primarily affected by the destruction process. The growth of dissolved organic carbon, aromatic substances, condensed carbon fragments in the structure of DOC components in the studied waters was observed in the first fifty hours of the experiment, then the corresponding indicators decreased, probably due to the mineralization of organic substances.
