Concentration and spatial distribution of metals in sloped vineyard soil at the Jazbina experimental station

U ovome radu provedeno je istraživanje ukupnih koncentracija metala (Cu, Cd, Co, Cr, Fe, Mn, Ni, Pb, Zn i Hg) u vinogradskom padinskom tlu na pokušalištu Jazbina u listopadu 2020. kada je uzeto 27 uzoraka tla s vrha (A), sredine (B) i dna padine (C) te s tri dubine (0-30, 30-60 i 60-90 cm) u triplikatu. Ukupne koncentracije metala određene su optičkom emisijskom spektroskopijom induktivno spregnutom plazmom. Statistički značajna razlika s obzirom na poziciju na padini utvrđena je za ukupnu koncentraciju Co u tlu (0-30 cm) pri čemu je ona bila značajno viša na dnu (14,5 mg kg-1) u odnosu na vrh padine (12,0 mg kg-1). Utvrđena je i značajna razlika u koncentraciji Cr u tlu (60-90 cm) pri čemu je viša koncentracija Cr bila na vrhu (45,2 mg kg-1) u odnosu na dno padine (35,2 mg kg-1), dok za ukupne koncentracije ostalih analiziranih metala nije utvrđena značajna razlika. Rezultati upućuju na to da nagib terena ima značajan utjecaj na prostornu raspodjelu određenih metala u padinskom tlu.In this Thesis, total concentrations of Cu, Cd, Co, Cr, Fe, Mn, Ni, Pb, Zn and Hg in sloped vineyard soil at the Jazbina experimental station were analyzed during October 2020. Total of 27 soil samples were taken in triplicate at the top (A), middle (B) and the bottom of the slope (C) at three soil depths (0-30, 30-60, 60-90 cm). Metal concentrations were determined using inductively coupled plasma optical emission spectrometry. Statistically significant difference in total concentrations of metals in soil in regard to the position on the slope (top, middle or bottom) was found only for Co (0-30 cm) with the highest concentration recorded at the bottom (14,5 mg kg-1), and the lowest at the top of the slope (12,0 mg kg-1); and for Cr (60-90 cm) with the highest concentration recorded at the top (45,2 mg kg-1), and the lowest at the bottom of the slope (35,2 mg kg-1). Results suggest that terrain slope has a significant effect on spatial distribution of certain metals in sloped soils
