To evaluate the possibility to use oregano as a cover surface on tailings deposits and thereby mitigate the emission of particulate material with metals content, an experiment was carried out comparing the plant growing rate over a period of six-month in four substrates： tailings, vermicompost, ＂soil＂ of the region and a mixture of ＂tailings plus vermicompost＂. The statistical analysis shows a significant difference between treatments, resulting in the ＂soil＂ substrate with the best performance, followed by the mixture of＂tailings plus vermicompost＂ treatment. The low permeability oftailings strongly affects the adaptability and growth of the oregano plant; however, the adaptation possibilities increase in the mixture oftailings with vermicompost or ＂soil＂ of the region.展开更多
