Nabor pXRF elementov v peri-urbanem zadrževalniku Brdnikova : raziskovalni podatki, obravnavani v članku

Golob, Nejc (author), Zupanc, Vesna (author)

Podatkovni nabor vsebuje georeferenčne talne vzorce iz suhega zadrževalnika Brdnikova v Ljubljani, vzorčene v zgornjem (A, 0–10 cm) in spodnjem sloju (D, 10–20 cm). Za vsak vzorec so z bench-top pXRF analizatorjem določene koncentracije 17 elementov (Ti, Cr, Fe, Ni, Cu, Zn, As, Rb, Sr, Zr, Pb, Mn, Al, Si, P, K, Ca), poleg izbranih fizikalno-kemijskih lastnosti tal (pH, električna prevodnost, organski ogljik, karbonati, skupni dušik, razmerje C/N ter rastlinam dostopen fosfor in kalij). Vključeni so identifikatorji vzorcev, razred rabe tal ter koordinati vzorčnih točk, kjer je to primerno. Nabor je uporabljen za primerjavo klasične z-score PCA in centrirane logaritmično-razmerne (CLR) PCA ter za robustno PCA, PERMANOVA in prostorsko analizo talne geokemije v retenzijskem bazenu. Podatki so objavljeni v obliki CSV, skupaj z reproducibilnim R workflowom za vse analize, povezane z objavljenim člankom.

• Title: pXRF element dataset from the peri-urban Brdnikova retention basin : research data underlying the article

Abstract

This dataset contains georeferenced soil samples from the dry retention basin Brdnikova in Ljubljana, Slovenia, collected in an upper layer (A, 0–10 cm) and a lower layer (D, 10–20 cm). For each sample, a bench-top pXRF analyzer was used to determine concentrations of 17 elements (Ti, Cr, Fe, Ni, Cu, Zn, As, Rb, Sr, Zr, Pb, Mn, Al, Si, P, K, Ca), together with selected physicochemical soil properties (pH in water, electrical conductivity, organic carbon, carbonate content, total nitrogen, C/N ratio, and plant-available phosphorus and potassium). The dataset includes sample identifiers, land-use classes, and sampling coordinates where appropriate. It is used to compare conventional z-score principal component analysis with centred log-ratio (CLR) PCA, and to perform robust PCA, PERMANOVA and spatial analysis of soil geochemistry in the retention basin. All data are published in CSV format, accompanied by a reproducible R workflow for the analyses linked to the associated article.
