The research was carried out on rye's very good complex (winter wheat, winter oilseed rape, spring barley) as well as on the good complex of rye's soil (potatoes). The aim of the research was to assess the effects of plants foliar fertilization with the 7 hydrate sulphate (VI) iron (II) applied in three concentrations according to standard fertilization on plants yield quantity. The results show that foliar fertilization of plants with the water solution of the 7 hydrate sulphate (VI) iron (II) waste in II and III concentration has increased the yields of potatoes tubers, winter wheat grains and winter oilseed rape seeds. The yields of spring barley increased only following the foliar fertilization with the water solution of the tested waste in I concentration. The water solution of FeSO4 ź 7H2O with the 6% addition of urea applied in concentrations II and III has caused further increase of the yields of all plants.
