Sažetak
Due to the formation of precipitous compounds, availability of Zn, Mn, Fe is reduced in alkaline, calcareous soils. Beside high pH values, high active lime content is the reason for lower uptake of the above mentioned nutrients. Thus, the objective of this trial was to define the impact of synthetic zeolites fertilization on leaf mineral content of olive leaves (Olea europaea L. cv Leccino) grown in the alkaline, calcareous soil. For this purpose, an experiment was conducted in the vegetation chamber, in the period of 200 days. Fertilization with Zn, Mn, Fe was carried out in the form of synthetic zeolite A (ZA), in which the original Na+ ions from zeolite A were exchanged with Zn2+, Mn2+ and Fe2+ (Fe3+) ions from solutions. Results showed that zeolite fertilization significantly increased Mn content in olive leaf, while Fe and Zn leaf concentrations did not show any significant difference between zeolite treated and untreated olives.
