Abstract:

Soil composition has an important role in food quality and safety. Sustainable management of heavy metals in agro-ecosystems is essential and the study of trace elements adsorption in soil and its translocation in crops is critical. The aim of this study was to evaluate the heavy metals and their natural isotopes content in an organic experimental field used for vegetable crops, prior to evaluating its uptake in plants and edible parts of different crops. Also, we looked at the correlations of the accumulation of the most important heavy metals (Mo, Cd, Cu, Pb, As, Cr, and Zn) depending of the different soil depths. The results found showed that the heavy metals content of an calcaric alluvial soil used in organic farming is according to European legislation and that the correlation found between these elements and soil depths can be an important indicator in the relation between heavy metals content in soils and plant uptake.
