Microelement composition research of Karelian peat soils at different stages of utilization

The content of copper, molybdenum, manganese, zinc and cobalt in Karelian peat soils at different stages of their development is studied. Overall, considering the content of the peat volume weight, the soils are characterized by the low content of mobile forms of trace elements. This fact has to be considered in case the soils are used for agricultural purposes of the region.
