Yakovenko V. Ecological role of biogenic microstructurization of the forest edaphotopes in southeast of the Ukraine.

The objects are the forest edaphotopes in southeast of the Ukraine. The aims is to study an ecological role of biogenic microstructurization in construction of a biological variety of forest edaphotopes in southeast of the Ukraine. Methods - micromorphologycal, the software packages "Statgraphics for Windows 5.0", "Statistica 5.5", "Exсel 2000". It is established, that the type of forest biogenocoenosis defines the character and the scales of biogenic microstructurization - the microstructure of genetic horizons, partisipation of biogenic structures in the general picture of the microstructural organization of edaphotopes, morphology of soil aggregates. The scales of biogenic microstructurization, value of saprophagic organisms during aggregation of the soil material in the number of soils: dark-chestnut, improved by forest-ordinary chernozem - ordinary chernozem, improved by forest-inundated meadov - forest soil - forest chernozem is increased, micro- and macrostructural state is improved. Uniformilyof intensity and character of biogenic microstructurization of soils in gully and inundated forests of Prysamar'ya is revealed. Stratification of structureformation activity of soil mesofauna in the structure in particular by features of the microstructural organization of edaphotopes is conditioned. The microstructure of zoogenic aggregates is investigated. Uniformily of the microstructure of exerement lumbricides and larva of insects is established. Interrelations between spatial parameters of water-stable soil aggregates are revealed. The analysis and the statistical substantiation of connection between the separate ecological characteristics of edaphotopes and spatial parameters of water-stable soil aggregates was carried out. Spheres of use are forestry and training courses.
