ECOLOGICAL DIFFERENTIATION OF VEGETATIVE COVER OF FALLOWS OF THE PRAVOBEREZHNY STEPPE PRIDNEPROVYE (ON THE PATTERN OF THE BUG-INGUL GEOBOTANICAL DISTRICT)
The data of edaphic environmental factors of plant communities of fallow lands in the southern part of Pravoberezhny steppe Pridneprovye have been analyzed. The stages of demutation and the species composition of fallow lands have been determined. The ordination analysis to identify the specific ecological character of fallow communities' habitat and to assess the ecotopic characteristics of the areas under study has been carried out. It is found that the basic factors influencing the differentiation of plant associations on fallow lands are moisture provision and the content of total nitrogen and calcium in the soil.
