"Głogów" copper works during its entire existence since 1971 emitted large amounts of dusts, heavy metals and industrial gases, particulary sulphur compounds. The influence of copper works on the nearest neighbourhood was extremely negative. Farms felt the presence of copper works in particular badly and the harmful effect was strongly marked within a radius of about 12 km. The goal of this study was to investigate the structure of direct inputs on crop cultivation, namely sugar beets, potatoes and cereals in two zones of ecological hazard, up to 6 km (I) and to 12 km (II) from the copper works. 245 farms, including 38 farms cultivating sugar beets, 70 potato growing farms and 137 cereals farms were studied. Plant protection inputs were shown by following indices: a) usage of biologically active substance per 1 ha with division into toxicity classes and generic groups, b) private costs of protective treatment. The studies showed, that the farms situated in zone I of copper works influence used more intensive plant protection than in zone II and that the profitability of pesticides use was higher in zone II.
