Translocation factor of metals from soils polluted with cadmium and zinc barley crop

Abstract

Translocation factors characterize how metal have access in different tissue part of the plant. They vary in function of metal nature, concentration in soil and plant particularities. Organic matter adding aimed to fertilize entail the increase of translocation factor value of metals present in soil to terrestrial parts, decreasing the reserves from root. The misture of organic matter in type of biosolids and pillared indigenous volcanic tuff aqueous suspension, had entailed the decrease of translocation factor TF (ratio between metal quantity from a part of tissue and total quantity of metal in plant). Cd, Zn and pB translocation factor from root to terrestrial parts is reduced with 70-92% related to unfertilize and non amended polluted soil.
