In the current research, heavy metals content (Zn, Ni, Cd, Cu, Pb) was analysed in soil and corn cobs samples to determine if the soil and corn plants are polluted with these heavy metals, corroborated with the humus content, total nitrogen, mobile forms of phosphorus and potassium, soil reaction, clay, sand and silt. Soil samples were collected from 9 parcels located in the Varvor area. Varvor is situated in the SW of Dolj County, 18 km from Craiova, and positioned in the northeast part of the Desnatui Plain, on the border with the high Balacita Plain. Following the results, was found that all values obtained for these parameters are falling below the established normal values by Order 756/1997, for sensitive soils. Only concerning Cu content of the analysed soil samples, the limit value of 20 mg kg-1 was exceeded for 6 of the 9 samples, the variation range being between 19.1-35.8 mg kg-1. Heavy metals content in corn cobs were within the acceptable limits according to Codex Alimentarius, except for cadmium, which exceeded the limit value established by Commission Regulation no. 1881/2006.
