Abstract
Effect of the deposits from the industrial-household sewage on the macro- and microelemental composition of a forest grass stand and of a young growth of pine and larch has been studied when the deposits are applied as an organic fertilizer. It was found that upon addition of deposits, the content of some chemical elements in soil is increased. Concentration of some elements (V, Mn, Ni, Cr, Zn) is as great as MPC. Plants of herbage react most actively to an increase in the concentration of chemical elements in soil with the deposit. The maximum changes have been registered in the elemental composition of roots of herbaceous plants.
