The results of a comprehensive analysis of the microelement composition of soils — B, Co, Cu, Mn, Mo, Ni, Zn and plants — Ag, Co, Cu, Mn, Mo, Ni, Pb, Zn (oak (Quercus robur L.), pine (Pinus sylvestris L.) perennial grasses — Kupena (Polygonatum multiflorum (L.) All.), wheatgrass (Elymus repens (L.) Gould)) of natural reserve belonging to different physical and geographical zones — Polessky reserve (mixed forest zone), Roztochya reserve (broad-leaved forest zone), Kanevsky reserve (forest-steppe zone), the reserve «Askania Nova» (steppe zone), the Chernogorsk massif of the Carpathian Biosphere Reserve (KBR, Ukrainian Carpathians), which are proposed to be considered as background. It was found that in the soils of mixed and broad-leaved forests and the Chernogorsk massif KBR with an increase in the content of gross forms of Co, Cu, Ni, Zn, the content of their mobile forms increases, this dependence is inverse in the soils of the steppe zone, which is associated with a decrease in soil acidity and mobility microelements A positive correlation was revealed between the humus content in soils and Zn, Co (gross and mobile forms) and negative — B, Mo in the soils of all reserve zones. It was found that the greatest biogeochemical activity is characteristic of plants in the zone of deciduous forests — oak leaves (Quercus robur L.) and pine needles (Pinus sylvestris L.).
