Research of microflora of soils in forest nurseries of the Vologda region

Soil is a separate natural unit, its protection is a top priority issue when it is used by industry or agriculture. Urban environment is subjected to different changes because of the intensive anthropogenic influence. The soil surface of urban areas needs much attention as well as traffic influence consequences. Industrial and building sites have great impact on soil diverting its components (agrochemical and physical ones). It interferes with its important ecological function. Microbiota, biochemical parameters of the soils, its biological activity are the first to change that is why they are considered by many explorers to be the most sensitive to pollution of soil layers. Green areas play an important role for the urban population. The scientists often do not take that areas into consideration because their soils are traditionally believed not to be subjected to intensive anthropogenic influence and do not cause much of pollution and hereby are not dangerous. Meanwhile small recreational zones within cities are often influenced by industrial factors, as a result the vegetation and soils worsen though they play an important role in environmental recovery and fulfil recreational and sanitary functions. We have measured soil fungi and bacteria by a reproduction and insemination method by placing the soil suspension into dense nutrient medium.
