Summary: Ecological relationship between soil properties (habitats) and floristic compostion of meadow associations and lower units of facies is established by phytocoenological and pedlogical methods of studioes. Fertilizer tests are set in different meadow associations according to uniform methodology, and changes in floristic composition, structure and quality of hay yield are established.

Keywords: ecosystem of lowland meadows, associations, habitat, fertilization

Research goals: Aims of the studies: - to establish ecological relationship between floristic composition of meadow associations and facies and pedological properties in a pedological soil profile in relation to forest associations and arable surfaces, - to establish fertilization effect in relation to floristic composition and soil propeties in meadow ecosystem, - to work out in detail a method of pedological mepping basedon knowledge of plant cover floristic system and its ecological indexes, - to establish the differences in soil erossion between ecosystem of meadows, forests and arable surfaces of the researched area, - to establish a disturbance of te present ecological balance in some associations due to land reclamtion, cultural operations and other activities based on knowledge of vigour and plant associations development and chamges in soil properties, - to plan meadow fertilization based on knowledge of floristic composition and soil properties, - to study conditions of soil and plant cover for a better leguminosae growth (clover) in order to swop nitrogenons fertilization with natural nitrogen fixation from air by means of symbiotic bacteria on leguminosae. Expected results of the studies: On the basis of the former studies we have established strong up to complete correlations between floristic composition of meadow associations and some soil properties and fertilization effect. There will be established in rolling topography some differences in thickness of geological substratum of aeolian diluvial clay between ecosystem of forests, meadows and arable land as a result of anthropogenic errosion, - to establish differences in soil properties between ecosystem.
