Organic amendments and Mediterranean plants on the stabilization of soil trace elements in an abandoned mining area
We investigated the effect of two organic amendments (biosolid compost and alperujo compost) and three vegetal species of different families (Poa annua Graminaceae), Medicago polymorpha (Leguminosae) and Malva sy/vestris (Ma/vaceae)) on stabilization of trace elements in a contaminated soil. Experimental soil come from an abandoned mining area located in Tharsis (Huelva), whose the main activity was the extraction of pyrite (FeS2)' This is an acid soil (pH 5.5) with high content of organic matter (9%). The experiment was carried out in pots (3 kg of soil) outdoors for 6 months (AprilOctober). A single addition of amendments (75 9 per pot) was made. Amendments were mixed with the first five centimeters of soil. Seeds of the species were established 3 days after amendment addition. Three soil samplings were performed: 3, 53 and 182 days after amendment addition. Results, after 6 months study, showed that amendment addition and plant growth lead to an in crease in conductivity, pH and TOC content and a decrease of Cd, Cr, Cu and Zn availability in soil. Concentration of trace elements in plants depends on the amendments and the species. In amended soils, concentrations of Cu, Cd and Zn in M. sy/vestris shoots decreased whereas elements as Co, Pb and Ni concentrations decreased in M. po/ymorpha and M. sylvestris. M. sylvestris accumulated a major quantity of Zn and Cd whereas P. annua presented higher levels of As, Cr and Pb. Levels of As in plants growing in amended soils decreased slightly. Arsenic concentration in M. po/ymorpha and M. sylvestris increased in time (June to October).
