Soil-to-plant transfer of radiocaesium in ipomoea aquatica

The effectiveness of the bio fertilizer regarding the growth promotion and radiocaesium (Cs) uptake was evaluated in Ipomoea aquatica. The growth of Ipomoea aquatica was enhanced with the application of bio fertilizer. The practice of bio fertilizer resulted in significant increase of Cs concentration in all plant parts and higher Cs transfer from soil to plants. TF values of Cs ranged from 0.555 to 6.726 for the species. The plant roots possessed the lightest weight after being harvest, and show a highest Cs concentration in plant roots. Ipomoea aquatica could be utilized for agricultural countermeasures and phytoremediation, to diminish the allocation of radiocaesium from soil to human.
