Characterization of soils on consolidated limestone and its relations to grassland vegetation

Understanding the relations between soil features and plant responses is important for agricultural production nature conservation. The aim of this study was to investigate importance influence soils? physical chemical on composition species richness in grasslands studied limestone massif eastern Serbia (Mt. Rtanj). data set included 22 phytosociological releves, same number corresponding mixed samples (0-10 cm depth) 8 profiles. Two vegetation types were distinguished by numerical classification as Saturejion montanae Festucion valesiacae. results detrended correspondence analysis (DCA) indicated that most parameters affecting dry humus, content calcium, exchange capacity base saturation, addition total acidity, pH depth. communities both are developed Leptosols Phaeozems. Under similar conditions soil, grassland exhibits differences floristic composition.
