We studied a landfill where toxic sludge derived from copper ore production is deposited. These types of landfills pose a threat to the surrounding environment because of the complete lack of vegetation and dust emission. Thus, the problem refers to the future recultivation of these areas. In order to improve the quality of the affected environment, thus allowing plants development, we applied biopreparations containing biosurfactants and microorganisms for the following plant species: Zea mays, Lupinus luteus, Pisum sativum, Avena sativa, and Sinapsis alba. We studied their influence on both germination and plant growth. It was found that applying biosurfactants before germination stimulates all studied seeds. This effective technique could be used for the reclamation of soil contaminated by post-flotation waste. However, the usefulness of biosurfactants for further plant growth was not proved.
