dc.description.abstract | We analyzed macro- (Ca, Mg, and K) and microelements (Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn)
in soil from three depths that correspond to different soil horizons (0-60, 61-75, and 76-160 cm) from
three sites in Futoški park (Novi Sad, Serbia), which was measured by using the atomic absorption
spectrophotometry (AAS). In this study, we tested the influence of spatial arrangement and soil depth
on the variation of micro- and macro-element contents using (i) two-way ANOVA with the site, soil
depth, and their interactions as dependent variables, (ii) Tukey post-hoc test (for p<0.05), and (iii)
principal component analyzes (PCA). Except for Cd, all measured samples are below of the limit value
prescribed by the Serbian national legislation. Likewise, Cr is very close to the maximum allowed
amount. According to the results of two-way ANOVA statistics, sites, soil depth, as well as their
interaction statistically significantly influenced the content of all examined macro- and micro-elements
in the analyzed soils. Following the PCA (which covers ˃90% of samples), surface horizons deviate
from all three sites, and stronger deviations between the first and the other two horizons which are
very similar were noted. In detail, on the surface horizon higher concentrations of K, Cu, Cr, Fe, Mn,
Ni, and Zn were detected, opposite to Ca, Cd, and Mg. | sr |
