Plant nutrient contents and spatial distribution patterns of toxic element concentrations in mine site soils

Open-pit coal mining causes land and soil degradation negatively affects properties. It is of great importance to determine variabilities in properties the abandoned area after mine closed bring it back nature by implementing appropriate rehabilitation programs. The aim this study was evaluate plant nutrient availability toxic element pollution an site. results indicated that amounts plant-available P K are quite low (<90 kg P2O5 ha-1) moderate (<170 K2O ha-1), respectively. concentrations available Fe (>4.5 mg kg-1) Cu (>0.2 too high whole Soils generally have organic matter content with ranging from 0.42% 3.67%. Toxic concentrations, especially Ni (>75 Cr (>100 kg-1), extremely above optimum levels, posing a risk open-pit (abandoned), dump sites storage area.
