Interaction of organic sorbents and liming in remediation of light soil contaminated with copper and zinc
The objective of the study has been to determine the effectiveness of organic sorbents (peat and coprolite humus) applied separately or together with liming in preventing the phytotoxic effect produced by excessive amounts of copper and zinc in light soil. The study was conducted in pot trials on white mustard. Phytotoxicity of the metals in light soil revealed itself very clearly at the level of soil contamination equal to 150 mg of a metal·kg<1> of soil. At higher levels of pollution (300 and 450 mg metal · kg<1> soil) complete reduction of yield was observed. High effectiveness of the above soil remediation methods in restoration of light soil productivity potential has been demonstrated, with the best effect obtained from pots treated with a combination of one of the sorbents and lime. The effectiveness of peat as a factor limiting the transfer of copper from soil to plant tissues was higher than that of coprolite humus, which in turn proved to be more effective in zinc contaminated soil.
