Özet
The aim of this research was to remediate the chrome (Cr) pollution in agriculture areas with canola (Brassica napus L.) plant. For this purpose, a field experiment was done Tekirdag Namik Kemal University Agricultural Faculty Research and Experiment Area in 2011 year, Turkey. Chrome contamination (100 mg/kg Cr) as Cr(NO3)(3), form was applied to the each parcel. Then EDTA chelate was applied to the each parcel four doses (0, 5, 10 and 15 mmol/kg) in blossom time of plants. The plants were harvested after four months growing. According to the results, root and shoot yield of plants decreased with increasing of EDTA doses. On the other hand, Cr contents of root and shoot of plants increased with increasing EDTA application to the plants. These increases and decreases were found significant statistically at the level of 1 %. According to the experiment results, Cr pollution can be remediated with phytoremediation method in Tekirdag province soils. In order to lower down the Cr heavy metal pollution on agricultural lands at 0-20 cm of soil depth to the toxicity level where normal culture plants are able to grow, it is necessary to apply 15 mmol/kg of EDTA or more. Because this study has proved that heavy metal (Cr), whose mobility has been increased by rising amounts of chelat applications, can be removed from soil through phytoremediation method.
