The research carried out indicated that agricultural yield increase and phytotoxicity decrease may be obtained in the severely polluted areas by amendments, organic, mineral and foliar fertilisation. The highest yield increases were obtained by mineral fertilisation with N100P100K100, by amendments (117 percent), bentonile (101 percent) and zeolitical tuff (123 percent). In the case of organic fertilisation, significant yield increases were obtained only by applying rates of 60-90 t on ha manure, which also led to the decrease of the Cu, Pb and Cd content in maize leaves by one third. Amendments led to the decrease of Cu, Pb and Cd concentrations in maize leaves by 50 percent.
