The Soil Fertility Control System covered a total of 15,826.11 ha at the Becej area (Backa region, Serbia, Yugoslavia) during the 1990-1996 period. Using samples that had been used to determine the main chemical properties of the soils and make recommendations for a cost-effective use of fertilizers, Cu content was measured to determine the supply of this microelement in the soils of the agroindustrial combine. The measurements have shown the following levels of Cu supply for the total area studied: medium supply - 5,294.94 ha (33.46), high supply - 8,583.66 ha (54.24), and very high supply - 1,917.51 ha (12.12). Toxic Cu levels (above 50 mg/kg) were found on only one plot, which was 30 ha in size (0.24 of the total area). The Cu supply in chernozem and black meadow soils has been found to be either medium or high, while the supply in hydromorphic and alluvial soils has been determined to be very high. The soil on the plot with the toxic Cu content is a limeless hydromorphic one.
