In this article, an anthropogenic influence on natural
ecosystem such as an excavation of sand is discussed.
Investigations were done in Kuyar Forest District of
the Mari El Republic on a sandpit. The adjacent plot
of natural forest was taken as a control. For evaluation
the degree of environment transformation as a result of
sand excavation several indicators were used. As
indicators of physical soil degradation - thickness of
organogenic horizon and soil density; for assessment a
chemical degradation – content of main nutrients and
humus; as an indicator of biological degradation – the
level of active microbial biomass. Besides, a potential
phytotoxicity was estimated. The study proved:
physical and chemical parameters corresponded with
the fourth degree of soil degradation, at the same time,
biological parameters approximated to parameters of
soil from natural territory
The effect of the new meliorants on the qualitative and quantitative composition of the microflora of loamy sand soil and the growth of pine seedlings is presented. The activization of microbiological processes and growth of plants on the meliorated plots is revealed
Human-induced disturbance on water objects was appraised with chemo and biological methods, the results of which are turned out to be comparable
The opportunity to apply products of beekeeping to the environmental control of territories polluted with radionuclides is examined
