Kazyuta A. Peculiarities of development and use of flood forest soils of the Seversky Donetz river in Forest-Steppe conditions.

Object - a natural flood soil formation on different parts of a flood land of the river Severski Donets under wood and grassy vegetation. The purpose - an determination of common laws of soil-flood development process under wood and grassy vegetation in conditions of a land and definition of ways of rational utilization of floodplain soils. Methods - general scientific and special. Theoretical results - evolutionary genetic investigations form a basis of the further development of the concept of an flood soil formation, they can be used at carrying out of models of rational lands using and increase of fertility of alluvial soils of the Forest Steppe of Ukraine. Practical results - the complex evaluation of properties and potentialities of soils will allow to optimize nature management in a valley Severski Donets, to increase land productivity which are used, to solve ecological problems. Novelty - for the first time in Ukraine features of genesis, structure and properties of alluvial soils of some ranges of a flood land of Severski Donets in area of the south of the Forest Steppe under a forest vegetation in comparison with grassy are in details explored. A degree of an introduction - materials work are used in branches of Institute of land management UAAS, in Ukrainian scientific research institute of a forestry named after G.M. Vysotsky, in the Ukrainian state design production association on the device of a wood „The Kharkіv state expedition on the device of a wood” and as in educational process in Kharkіv NAU named after V.V. Dokuchayev, at the Kharkіv state pedagogical university named after G.S. Scovoroda. Range - a agricultural.
