Essay

Object of the investigation - natural flood plain pedolitogenesis and produced by it young, ecological vulnerable, kaleidoscopic, dynamical alluvial and peat soils of flood lands of Polissya and Forest-Steppe of Ukraine (basins of Dnipro, S.Dinets) and other countries. Aim of investigation - deep analysis of the results of correcting effect of anthropogenic activity upon flood soils formed in the valley landscape; making of ecology-oriented multivariant models of cultural pedogenesis in flood land and valley landscapes. The methods of the investigations and equipment - stationary-field, historical-genetic (evolutional), biogeochemical (landscape-geochemical), methods with application of information technologies; the data were processed mathematically using application packages MathCAD 6.0 Plus, Statistica 5.0. The theoretical results. Conceptual idea of evolutionally developed flood land and valley pedogenesis has been formulated, regularities of natural soil formation and corrections introduced into it in the process of cultivation of food plain ecosystems of polyfunctional destination have been established; landscape typology of flood land as a basis of ecologically proved business managing within valley landscapes has been developed; theoretical bases of phytoagrochemical cultivation of virgin flood lands have been updated on the base of biosphere-centered principles; biogeochemical, ecological regularities and evolutional trends of cultivating correction of natural flood soil formation have been itemized; ecology-directed approaches to settling the collision between increase of bio-productivity of flood land ecosystems and reduction of soil-cenotic biological diversity in the process of phytoagrochemical cultivation of virgin soils have been proposed; independent ecological expertise of projects aimed at management of flood land territories has been proposed; scenarios of rational using of flood land ecosystems have been updated. The practical results - phytoagrochemical cultivation of virgin soils with the account of the carried out landscape-ecological land typology; biosphere-centered principles of cultivating correction of flood soil formation. Innovations - ecoethic approaches to cultivating of flood land and valley soils, phytoagrochemical cultivation of their virgin variants in ecology-oriented systems of land management, itemizing of eco-biogeochemical regularities and evolution tredts of flood soil formation (including its cultivating correction), experience of executing of independent ecological expertise.The degree of implementation. Theory and practice of phytoagrochemical cultivation of flood land soils, landscape ecological typology of flood land, ecoethic approaches to land planning and farm using of flood land and valley landscapes are approved for implementation by Central Directorate of agriculture and foodstuffs of Kharkiv region state administration, Kharkiv oblast land resources department, the Land Management Institute of UAAS; biosphere-centered principles of cultivating correction of flood soil formation were introduced in the syllabuses of 6 Kharkiv educational institutions and Yur. Fedkovych Chernovtsy National University; the teaching syllabus and methodological support developed for the new speciality "ecologist of agricultural territories and enterenterprises" are implemented in the educational process at Kharkiv NAU; in Kharkiv oblast landscape reservation were arranged based on author's recommendations, also proposals on independent expertise of projects were introduced in expert practice of Kharkiv oblast ecological security department. Wide community of agronomists, land surveyors, farming economists, ecologists etc and land owners got open access to all these recommendations, which are used in Ukraine, other countries during land reforms, ecological expertise, in recreational, environmental and other ecosocial activities, having urgent necessity in modernizing relationship between man and earth. Area of application - ecologization of agriculture, pedagogical process, land usemanagement.
