Sažetak (engleski)
Various extraction methods are used to predict plant uptake of trace metals. Most commonly it is total concentration that is used for risk assessment and evaluation of trace metal availability. However, recent studies showed that total concentration is a poor indicator of availability while concentrations in soil solution show good correlation with plant uptake. Present study was conducted on magricultural soils with low levels of trace metals where 45 soil samples were collected from different soil types. The main objective was to compare four different extraction methods and examine how total and reactive (EDTA) trace metal concentrations correlate ,with soil solution concentration (in this study determined by water extraction). The samples were analyzed by four extraction methods: strong acid extraction (ultra-pure HNO3 extraction and aqua regia), weak acid extraction by EDTA and the most available fraction, fraction in soil solution, were represented by water extraction (weakest extractant). Five elements were investigated (Cd, Cu, Fe, Mn and Zn). Water extraction significantly correlated with EDTA extraction for Cu, Fe and Mn, while total extraction (HNO3 extraction and aqua regia) correlated significantly with water extraction only for Cu. No correlation between water extraction and total extraction confirmed poor role of total concentration as an indicator of availability. EDTA extraction can be used to represent reactive pool of trace metals in soil but it should be also taken with caution when using it to describe available fraction.
