Abstract
Soil contamination with heavy metals is a growing issue that results in adverse effects on plant production. In this study, the influence of manures on heavy metals toxicity reduction in Sinapis alba L. and Robinia pseudoacacia L. was tested in order to plan phytoremediation process The primary objective was to assess the effects of manure fertilization on plants grown on highly degraded soil contaminated by a range of heavy metals. The measurement endpoints used were seed germination, plants biomass, roots length, guaiacol peroxidase activity (GPX) and protein concentration. The study showed that among other stress markers, GPX activity showed statistically significant changes (α < 0.05) between different types of manures and between the 5% different in applied doses. Therefore performed tests could be used as efficient protocols to assess the required doses of organic amendments in planning of phytoremediation process.
