Microbiological researches of soils in city green plantations of Volgograd region

Soil is independent natural object which is sub-ject to protection, dictates a priority of ensuring preservation of soils at implementation in economic or other activity. At the present stage of develop-ment of society urban system scales increase. Ur-ban areas environment is exposed to various changes owing to intensive anthropogenous load-ing. The condition of a soil cover of urban areas demands close attention as influence of transport system, industrial production, the construction sphere puts constant pressure upon the soil envi-ronment, changing practically all its components, since agrochemical and physical properties and finishing with microbiological and biochemical pa-rameters, depriving a soil cover in the cities of the ability to carry out important ecological functions. Microbiota, biochemical parameters of the soil, its biological activity under the influence of anthropogenous influence change first of all there-fore are considered by many explorers as the indi-cators of a soil cover condition, most sensitive to pollution. In city landscapes interesting and im-portant for the city and the population the place is taken by the territories occupied with green plant-ings. Often these zones of the cities drop out of the field of vision of researchers as traditionally it is considered that soils of these territories are not exposed to intensive anthropogenous influence and transformation, and, therefore, the level of pol-lution of such ecosystems is low, that is their state should not cause fears. Meanwhile recreational territories, small in the area, in city boundaries of-ten come under strong technogenic influence, the condition of vegetation and the soil of these territo-ries worsen as a result. While recreational territo-ries of the city play an important role in the im-provement of environment, carrying out the major recreational and sanitary and hygienic functions. We measured soil fungi and bacteria by reproduc-tion and insemination method by placing the soil suspension into dense nutrient mediums.
