Zholudeva I. Soil formation in technogenic landscapes of Donbass

Object - Soil formation processes under natural grassy and forest planting ecosystems on the planned spoil heaps of Chasov-Yarsky refractory clays-field. Purpose - study of the general regularities of the development of the initial Soil formation processes under forest and grassy planting in the techogenic landscapes of Donbass. Methods - relatively-profile-genetic, laboratory-analytical research, methods of correlative and dispersive analyses. Theoretical results - changes of physical, physical-chemical, chemical and biological characteristic of techogenic soils as a result of soil formation processes were determined. It is proved that as a basic test for estimation of the temper and directions of soil formation processes in technogenic landscapes and soils diagnostic can serve their humus state. For the first time quantitative estimation of the energy condition young soils of technogenic landscapes was organized, which indicative of degree of remoteness them from stable condition of zonal soils. It is estimated that main parameter of the forecast of the selfdevelopment of the profile of technogenic soils is a spare in them organic material. Practical results – rate of the accumulation organic material in technogenic soil at age 35-37 years is installed. For the first time in Ukraine by experimental way factors of the energy feature of young soils of technogenic landscapes are received. Forecast of the humus accumulation and its distribution on profile in technogenic soils is made. Novelty - lays in theoretical motivation of soils forming on sedimentary rocks in the technogeniс landscapes of Donbass, as difficult natural educations which fasten the evolutional changes and aim to get back to the state of mature zonal soil. It is set, that selfdevelopment of soils on the initial stage of soil formation take place the intensive rate on zonal type, a dominant role in which belongs to the sod process. Dependence of rates of accumulation of organic matter in young soils from the type of vegetation and properties of parent rock is set. The model of selfdevelopment of profile of technogeniс soils in the Donbass conditions is developed. Degree of application - results of dissertation work are a basis for development of conception of the initial process of Soil formation on sedimentary rocks in Donbass. Results of work are can be used for the scientific motivation type and directions of reclamation, constructing of profile of technogeniс soil, and also for making the models rational and ecological-safety using of the reclamation lands. Materials of dissertation work can be used in educational process as part of teaching disciplines on soil science and soil protection. The field is scientifically-educational and nature protective.
