Depression of the Baia Mare is known like an area strongly affected by the mining activities performed here the centuries.These activities have generated important polluted areas, which even today, are subject directly to the pollutant impact. This paper presents the results of research conducted in the experimental plots, located near the tailing ponds, from the west part of Baia Mare. The chemical analyses conducted at the beginning of the study showed a small content of the total nitrogen, a high content of micro nutrients – copper, manganese and zinc, and specific pollutant – lead, and acidic reaction of the soil. Differentiated fertilisations applied, does not demonstrates that this fact affect the mobilization and accessibility of the four metals and indicating therefore, the possibility to be translocated in the throphic chain soil-plant-human. The study demonstrates the needs to implement urgent measures for environmental remediation of these soils to restore agricultural capacity of these soils.
