Abstract
Zinc (Zn) content was assayed in the farming soils of Suszec commune (agricultural and mining district in southern Poland). Its content in the soils (n=1227) assayed by means of atomic absorption spectrophotometry (AAS) ranged from 22.8 to 177.1 mg/kg. The enrichment factor (EF) calculated by using calcium as a reference element fell within a range of 0.66–2.63. The mean values of the enrichment factor classified the soil as slightly contaminated with zinc. The values of EF less than 1 pointing to zinc deficiency in the soil were found for 52% of the samples tested. Acid soils with low humus content showed a tendency for zinc‐deficient samples to significantly increase in number.
