Abstract
To investigate the effect of organic and inorganic amendments on heavy metal immobilization in soil and organic carbon sequestration, a growth chamber study over a period of 18 months was conducted. Phytoremediation of two degraded soils, smelter-polluted soil and post-mining soil, was carried out using Scots Pine (Pinus Sylvestris L.) and Giant Miscanthus (Miscanthus x Giganteus). The increase in organic carbon content for lake chalk amended soils was noted. In addition, the largest root biomass production after fertilization of heavy metal contaminated soil with lake chalk was observed. This soil additive increases soil pH and reduces heavy metal mobility, which finally minimizes the harmful effect of metals on plant life and growth. Root biomass production of Giant Miscanthus was significantly higher than Scots Pine root biomass for both soils. This may indicate better phytosequestration properties of Giant Miscanthus, especially in the case of land degradation due to mining and destruction of soil profiles.
