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.

The research on foliar fertilization with the water solution of the 7 hydrate sulphate (VI) iron (II) applied with and without an addition of urea, was carried out. Three concentrations of the water solution of the waste were used. The results of the research show that because of the waste water solution influence, the content of nitrogen has increased in potato tubers and in spring barley grains. The addition of urea to the water solution of 7 hydrate sulphate (VI) iron (II), has caused an increase of the nitrogen content in the studied plants. Foliar fertilization with the water solution of the 7 hydrate sulphate (VI) iron (II) with and without the addition of urea, did not have a distinct impact on the content of phosphorus, calcium, potassium and magnesium in the studied plants. Foliar fertilization with FeSO4 ź 7H2O water solution with and without the addition of urea as well as the concentration of solutions with the waste in most cases, has increased the content of sulphur and iron in the studied plants.

Część I. Badania nad możliwością rolniczego wykorzystania odpadów wytwarzanych w Zakładach Chemicznych 'Police' S.A. W latach 1996-1997 przeprowadzono doświadczenia wazonowe na glebach pobranych z warstwy ornej charakteryzującej się składem granulometrycznym piasku gliniastego (kompleks żytni dobry). Celem podjętych badań było określenie wpływu różnych dawek 7 hydratu siarczanu (VI) żelaza (II) stosowanych na tle nawozów wieloskładnikowych na wysokość i cechy jakościowe plonów roślin testowych. Roślinami testowanymi były: koniczyna czerwona, mieszanka rekultywacyjna traw (45% kostrzewy czerwonej, 35% życicy trwałej i 20% wiechliny łąkowej) oraz rzodkiewka odmiany Sopel Lodu. Uzyskane wyniki badań wskazują, że hydrat siarczanu (VI) żelaza (II): - nie ma wpływu na podniesienie się plonów roślin, - podnosi we wszystkich roślinach zawartość azotu, a zatem też białka surowego, siarki oraz żelaza, - nie ma ujemnego wpływu na koncentrację, w roślinach testowych fosforu, potasu, wapnia i magnezu. Nie oddziałuje na kolejne wejścia tych składników do roślin, - zmniejsza koncentrację bądź oddziałuje na wzrost w roślinach testowych zawartości kadmu, niklu, ołowiu i manganu. Wynika z tego, że odpad ten ogranicza w wielu wypadkach pobranie przez rośliny nieltórych metali ciężkich.

I. Investigations on the agricultural usefulness of the wastes produced by the 'Police' Chemical Plant In the years 1996-1997, pot experiments were conducted with a growing medium being the upper layer of a cultivated soil granulometrically corresponding with a medium sand of a good rye complex. The aim of the investigations was to determine the influence of different rates of 7 iron(II)sulfate(VI)hydrate applied along with a multicomponent fertilizer on the quantitative and qualitative properties of the yield of test plants. The test plants were red clover, a reclaimable grass mixture (45% of red fescue, 35% perennial ryegrass and 20% of meadow bluegrass) and small radish cv. Sopel Lodu. The investigation results indicate that 7 iron(II)sulfate(VI)hydrate: - does not influence that amount of the yield of plants, - increased the content of nitrogen and, thereby, crude protein, sulfur and iron in all the plants used, - has no negative influence on the concentration of phosphorous, potassium, calcium and magnesium in the test plants and did not inhibit the absorption of these elements by plants, - decreased or did not influence the concentrations of cadmium, nickel, lead and manganese in the test plants. This suggests that this preparation inhibits in many cases the absorption of some heavy metals by plants.
