“…Mine tailings impose various adverse effects on plant growth, particularly high levels of heavy metals and other elements in toxic concentrations but also low amounts of plant nutrients, acidity, salinity, alkalinity and poor physical structure [1,10,25]. Normal growth of plant is achieved when pH ranges from 4 to 9, therefore pH value of the studied tailing site is within the normal ranges for plant growth.…”

“…The maximum height of post-fl otation tank is 32 m and the target functional capacity has been assessed as 19.4 . Particles size of deposits with the majority of fractions with 0.06 mm of diameter facilitates the dust dispersion into bordering areas and infl uences fl ora growth [10,11,20,27]. Tailings samples were collected from the top 20 cm of tailings pond.…”

“…The alkalinity of waste is at the same time the limiting or entirely blocking factor when it comes to the availability of nitrogen and phosphorus for plants [8,10,11,20,27]. Metal presence, low levels of major plant nutrients and poor physical structure of waste are the reasons why it is hard to restore biological life in places when the waste is stored [8,10,11,20,27]. The natural succession of the biocenosis occurs very slowly and the reclamation of tanks does not always end with the success.…”

"Wartowice" tailings pond was closed in 1989, resulting in 232,4 ha tailings pile requiring reclamation. The major problem is heavy metals presence and poor nutrient conditions and physicochemical structure of soil which disturbs the plants development. In order to assess the real condition of studied area the complete biological characteristic has been done. The physicochemical conditions were assessed altogether with phytosociological, microbiological and toxicological studies of deposits. We recorded only 27 species of vascular plants belonging to 15 families on the tailings pond of which 5 belong to Rosaceae, 4 to Asteraceae and 3 to Poaceae and Saliceae. Species inhabiting the tailings depended on their dispersal capacity, metal tolerance and rhizome strategy. Microbiological analyses revealed the low number of bacteria and fungi on the tailings pond, apart from the small uplift area where the plants were indentifi ed. Bacteria identifi ed on the tailings pond were classifi ed to 8 genera. The low number of bacteria suggests the lack of nutrients which affects the development of soil microfl ora. Toxicity tests showed that post-fl otation sludge is not toxic to microorganisms because of its high pH. Some plants, such as lucerne could even infl uence positively the microorganisms development what has been proved in our studies. The tailings toxicity was higher towards producers, where Secale cereale appeared to be the most sensitive species. Amendment with topsoil from adjacent areas can infl uence positively the phytotoxic properties of tailings and enrich them into native seeds.
