Abstrakt
Mine waste poses significant environmental hazards due to high concentrations of potentially toxic elements. One method of waste heap reclamation involves introducing mineral-organic fertilisers and sorbents. Since microbiological activity is a sensitive indicator of environmental changes, this study, which was based on pot experiment, investigated the effect of chicken manure, biochar and bentonite (1%, 20% and 10% of technosol weight, respectively), as well as an organo-zeolite sorbent i.e. a mixture of chicken manure, perlite and CaCO₃ (1%, 5% and 3%, respectively) on the number of microorganisms and enzymatic activity in and around the Maximilián heap in Špania Dolina. Each pot was also sown with a grass mixture of Agrostis capillaris, A. stolonifera, Festuca rubra and Poa pratensis was sown in each pot. Compared with untreated technosol, chicken manure, organo-zeolite sorbent and biochar significantly increased the total number of bacteria, copiotrophs, cellulolytic bacteria, proteolytic microorganisms and oligotrophs. The addition of bentonite increased the number of oligotrophs and cellulolytic fungi. The highest biochemical activity was observed after organo-zeolite application but the lowest after addition of bentonite.
