| Biochar is used in Cd-contaminated soils to improve soil physico-chemical characteristics and thus may provide reliable crop production under Cd toxicity. A greenhouse experiment was conducted to investigate the effects of two mahalep biochar doses, Cd forms and doses on growth, Cd and micronutrient uptake of tobacco plants (Katerini genotype) in Cd-contaminated soils. Three different cadmium forms {3(CdSO4). 8H2O, Cd(NO3) 2.4H2O and CdCl2} and 4 different cadmium doses (0, 2.5, 5.0 and 10 mg Cd kg-1 soil) were experimented together with two different mahalep biochar treatments (BC0-%0 and BC1-%1 w/w). Soil DTPA-extractable Cd concentrations and shoot Cd concentrations (P<0.01) were significantly increased with biochar doses, but shoot dry matter yield (P<0.01) was significantly reduced. Soil and plant Cd concentrations were reduced by biochar treatments in all Cd forms and doses. The greatest reduction in Cd uptake was observed in CdCl2 (175% reduction) and the least reduction was in CdNO3 (25.4% reduction) forms. Biochar treatments resulted in higher shoot dry matter yields in all Cd forms and doses. The average shoot dry matter yield of 3(CdSO4). 8H2O form was 4.91 g plant-1 at BC0 treatment and the value increased to 5.85 g plant-1 at BC1 treatment. Such a case was also valid for the other Cd forms. Average dry matter yield of Cd(NO3)2.4H2O form increased from 4.78 to 5.29 g plant-1 and the value of CdCl2 form increased from 5.09 to 5.45 g plant-1. Regardless of Cd forms, it was concluded that biochar reduced Cd uptake of tobacco plants. |
