Translocation of Trace Elements from Sewage Sludge Amendments to Plants in a Reclaimed Area

The goal of the study was to evaluate bioaccumulation of trace elements in plants grown in post-mining soils amended with the biosolids material. Phaseolus vulgaris was investigated on the laboratory scale, and a mixture of grasses, Melilotus albus, Beta vulgaris, Zea mays L. and Miscanthus × giganteus were evaluated on the field scale. The results of the research showed that P. vulgaris fertilized with the Carbocrash substrate was able to grow. In addition, growth was enhanced following stimulation with gibberellic acid. Transfer of trace elements should be evaluated on the plot scale. Therefore, we monitored the level of trace elements on an experimental plot in a reclaimed area. Crops plants were sown in multi-year periods. During the growing season the mixture of grasses and crop plants had a low bioaccumulation factor, which also showed a positive effect of fertilization with the Carbocrash substrate.
