Romaniv P. Geographico-genetic characteristics of physical condition of soils in Precarpathia

The dissertation is dedicated to the investigation of physical condition of background soils of Precarpathia, especially on the level of macrostructure and the lay of the land. On the macro-aggregate level the main physical characteristics of structural aggregates are defined: density of constitution, porosity, mechanical solidity (coherence). Spatial-lay character of the change of general physical characteristics and grain-metric and micro-aggregate condition of soils is analyzed. Morphometric characteristics of macro-aggregates are described and the factors of their transformation in the process of agricultural usage of soils are analyzed.
