Selective phytoamelioration of soils in Kursk oblast

Resumo

Data on zinc accumulation by saperda mustard and common barley grown on typical chernozem (Voronic Chernozems) and gray forest soil (Greyic Phaeozems Albic) in Kursk oblast are given. The revealed high phytoextraction capability of saperda mustard on gray forest soil depends on the content of total and available zinc. It has been found that the accumulation capability of common barley is similar on both soil types. The phytoextraction rate of the root systems of the studied plants is greater than that of their sprouts. Biological removal of zinc from soil by plants is up to 4.46 kg/ha. Saperda mustard and common barley are potential phytoremediation plants for zinc-contaminated gray forest soil and typical chernozem.
