Study on soil quality in different functional zones of Sofia region

The present study deals with examining the condition of urban soils and their potential to deliver soil-related regulating ecosystem services concerning level anthropogenic pressure in different functional zones Sofia, Bulgaria. Analyses data for selected characteristics superficial 0-10 cm soil layer were performed. Soils sampled from 30 experimental plots within a geo-referred network covering peri-urban territories. concentrations heavy metals Cu, Zn, Pb Fe analysed determine pollution, while pH, cation-exchange capacity (CEC), total carbon nitrogen content used as indicators assessing service “soil quality”. results demonstrate differences four – green zones, industrial residential agriculture, regulate maintain purpose assessment is outline implicating mitigation measures based on maps quality, which contributes focusing more attention protection restoration soils, reduce pollution increase reuse soils.
