“…The initiative was repeatedly dis cussed, and there were some doubts about the dis agreement with the principles of this system and the feasibility of extrapolating the Moscow proposals for different urban environments. The need to improve the diagnostic criteria was stressed [12].…”

The results of the Internet discussion on the classification of urban soils aimed at evaluating their possible inclusion into the modern Russian soil classification system adopted by a wide range of specialists are presented. The first step was to address the urban diagnostic horizons as the basis for identifying soil types according to the rules of the Russian soil classification. New diagnostic horizons were proposed for urban soils: urbic (UR), filled compost-mineral (RAT), and filled peat (RT). The combination of these horizons with other diagnostic horizons and layers of technogenic materials correspond to different soil types. At the subtype level, the diagnostic properties (qualifiers) that may reflect both natural phenomena (gley, alkalinity) and technogenic impacts on the soils (urbistratified; phosphatic; or poorly expressed urban-ur, rat, rt) are used. Some corrections were proposed for the system of parent materials in urban environments. Urban soils formerly described in another nomenclature-urbanozems, urbiquasizems, and culturozems-are corre lated with the taxa in all the trunks of the system. The proposals accepted can be used for the next updated version of the new Russian soil classification system.

Industrial technogenesis is considered as an independent soil-forming process resulting in a special type of soils, i.e. industrial soils. Their diagnostic horizon is the genetic horizon FR formed by substances and objects involved in the production cycle and industrial construction. The soil cover of the territories of factories, industrial complexes, mines, power plants, and industrial zones in general is represented by the dominant industrial soils, as well as by other types of altered/man-made soils. In general, industrial soils cannot be regarded as a sort of urban and chemically contaminated soils as it follows from the presented examples of technogenic soil-forming substrates and industrial sites of sugar mills in Ukraine. It is shown that, when the effect of technogenesis is removed or attenuated, the processes of juvenile soil formation and ecological demutation develop on technogenic substrates and industrial sites of sugar mills. The leading natural components of such industrial demutation are sod and humus formation and gley and dealluvial processes. Specific technogenic demutation processes include squeeze-humus formation, elemental sulfur oxidation, lime quenching, etc. During about 100 years of dealluvial inwashing processes in demutating industrial grounds of abandoned sugar mills there may be formed humus horizons of an up to 50 cm capacity, which leads to the formation of young chernozem soils on industrial grounds. Soil-forming substrates and soils of abandoned sugar mills are avidly occupied by vegetation, which forms communities referred to Artemisietea vulgaris, Robinietea and Sisymbrietea classes.

“…The second negative effect is contamination of soil by pesticides and their metabolites. A specificity of pesticidal contamination is that the morphology of soil, its chemical and water-physical properties do not change, but the soil gets "selective fertility" (Lebedeva et al, 1990), i.e. starts influencing organisms as depending on their genetic nature.…”

SUMMARYThe use of pesticides during cultivation of pine seedlings in forest nurseries results in the formation two phenotypes of teratomorph seedlings -conditionally normal and abnormal. Growing forest cultures from teratomorph seedlings leads to their low survival rate. It is known that pesticides and their metabolic products can remain in soil for many years. It is therefore impossible to rely only on natural degradation of pesticides in soil. A promising way of removing pesticides from soil is their microbiological decomposition. This method is preferable because there is a meliorative organic substance not far from forest nurseries -i.e. forest litter rich in microorganisms. The purpose of these experiments was to examine the influence of forest litter applied on pesticide decomposition in soil and morphology of pine seedlings. The rates of forest litter that were most effective in decomposition of pesticides and the activity of microbial communities in litter, depending on forest stand structure, were determined. Estimation of that action was based on the morphology of seedlings (rate of pine seedlings with normal, conditionally normal and abnormal phenotypes), intensity of CO 2 emission from soil and catalase activity, which correlates with the number of soil microorganisms. The results of these experiments showed the most effective activity of forest litter at the application rate of 20 kg/m 2 . The number of seedlings with normal phenotype rose from 32% up to 40%. Besides, it was noted that saprophytes were most effective in pine forest litter, which is characterized by a more acid reaction of soil solution, while most others were rich in fungi. The highest number of normal phenotype seedlings, intensity of CO 2 emission and activity of soil catalase were correlated with the microbiological activity of the applied pine forest litter.
