Geoecological study of the soil microbial communities of the natural and agricultural ecosystems in the south-eastern Baltic sea region

摘要

The number of different groups of soil microorganisms in the natural and agricultural ecosystems of the Kaliningrad Peninsula and the Curonian Spit was studied. It has been established that the studied ecosystems are distinguished by different types of soil, physicochem-ical parameters and the ratio of the main representatives of the soil microbial community: ammonifying microorganisms; microorganisms using mineral forms of nitrogen; nitrogen-fixing and oligonitrophilic microorganisms; cellulose-depleting microorganisms; aerobic spore-forming bacteria; microscopic fungi. The total content of different groups of microorganisms reflects the biological activity of the soil, which characterises its resistance and self-cleaning ability, which can be used in the study of modified soils under anthropogenic conditions.
