Fruška gora mountainous environments - assessing the impact of geological setting and land use on soil properties

Abstract

On a global scale, it has been found that in the last decades the surface of the vulnerable land and land affected by degradation is increasing and that unsustainable land management is one of the key drivers of land degradation. In order to assess the effect that these changes have on biodiversity and ecosystem services, and to carry out the appropriate planning and management actions for conserving the environment it is essential to identify and quantify changes caused by land degradation. The aim of this study was to determine the impact of geological setting i.e. type of bedrock, and land use on soil physico-chemical properties in vulnerable mountainous areas of Fruškagora. For the purpose of this study the total of 30 soil samples at 0-20 cm depth were collected at four locations on the Fruškagora Mt. Geological setting was serpentinite and marl and land cover was forest and meadow. Following soil properties were determined: pH, redox potential (Eh), electrical conductivity (EC), total dissolved solids (TDS), concentrations of available cations Ca, Mg, K, Na, contents of organic carbon (Corg) and nitrogen (N). The correlation between the obtained parameters was tested with two-way ANOVA and Principal Component Analyses (PCA). All of the obtained results indicate that the soil physico-chemical properties depend on geological setting and that rock composition has to be taken into consideration during land management.
