We used induced phytoextraction to follow the effect of ethylene glycol tetraacetic acid (EGTA) on increase of cadmium transfer from contaminated soil (5mgCd*kg-1 and 10mgCd*kg-1) to maize plants (Zea mays L.). In the pot experiments, uptake of cadmium into roots and green parts increased after application of the chelating agent. Addition of 6mmolEGTA*kg-1 affected 90% of Cd increase in roots in comparison with EGTA non-treated variant. In green parts, addition of 6 and 12mmolEGTA*kg-1 resulted in 100% increase at the same level of Cd contamination of soil substrata. The efficiency of cadmium uptake by maize doubled after addition of 6mmolEGTA*kg-1 into contaminated soil. Application of 12mmolEGTA*kg-1 in the soil, contaminated with 10mgCd*kg-1, resulted to twofold enhancement of cadmium uptake by the maize. The results showed that induced phytoextraction can decrease cadmium content in the soil to the level convenient for growing of hygienic clean crops.
