ABSTRACT
The paper contains the evaluation of the reclamation efficiencyon coal combustion waste deposits fertilized with composts and sewage sludge. Based on multiannual studies, the dynamics of changes in vegetation in the performed experiment have been shown. The firstphase of the experiment concerning the reclamation efficiencyof the employed fertilizers was carried out from 2006 to 2007. The second phase was carried out between 2011 and 2012. In order to show a broader spectrum of dynamics of changes in vegetation, the floristicobservation was repeated in 2013 and this paper is the presentation of its outcome. Based on the observation (2011–2013) and its results it was found that apart from plants cultivated in experimental containers also a self-sown florahas had a significantcontribution in shap-ing the vegetation cover. The results of floristic and ecological research have proven that composts and sewage sludge constitute a favorable environment for the development of spontaneous vegetation cover on coal combustion waste deposits. Based on the evaluation of the vegetation cover level in particular models it was shown that models with Complex composts (kC) and Radiowo ones (kRa) as well as the model with sewage sludge have pre-sented the highest reclamation efficienc. The lowest efficiencyhas been shown in models with ZUSOK composts (kZ) and the plant ones (kr). The conclusions have highlighted the share of ecological, systematic and syntaxonomic plant groups in the process of reclamation of combustion waste deposits.
