“…However, other studies (e.g., [84]) showed that extracting agents such as EDTA can not be used as universal soil extraction for estimating Cu, Zn, and Ni uptake by barley. Peijnenburg et al [85] made an overview of empirical methods for extraction of metals from soils as a surrogate for bioavailable and bioaccessible metal pools.…”

Two commonly applied single extractions procedures, namely extractions with ammonium-EDTA and acetic acid, were evaluated based on the analysis of 72 samples from alluvial sediments. For most trace elements (Cu, Zn, Cd, Ni, As, and Pb), a significant linear relationship could be established between their ammonium-EDTA or acetic acid extractable concentrations and their total concentrations, the organic carbon content, pH, and Fe , Al, and/or Ca content in the sediments. The scientific understanding of trace element partitioning in the complex soil-water system with these simple models is rather limited, but they offer the opportunity to use data from single extractions in a more comprehensive way. Despite the fact that these extractions cannot directly be related to the bioavailability of elements, they can provide input data for use in risk assessment models. Additionally, they also offer possibilities to perform a fast screening of the mobilizable pool of elements in soils and/or sediments.

“…McBride et al (2003) recommend diluted CaCl 2 as a universal extractant for assessment of the availability of trace metals to plants. Soriano-Disla et al (2010) demonstrated that solution of low-molecular-weight organic acids can be used as a universal extractant to foresee the uptake of copper (Cu), Zn, and Ni by barley.…”

In Poland, assessment of the content of micronutrients in soil is performed using 1 M hydrochloric acid (HCl) as an extractant. The objective of this study has been to check whether 1 M HCl can be replaced by Mehlich 3. In total, 330 soil samples were taken from fields cropped with winter wheat. Each sample was accompanied by a sample of wheat plant. The samples were from four groups of soils having various pH values-from acidic to alkaline soils. The suitability of the extractants was evaluated separately for each soil group based on the significance and power of correlation between soil microelements extracted by both methods, soil and plant microelements, and the bioaccumulation factor. The HCl extractant was a better predictor of the availability of microelements to wheat than Mehlich 3 in all tested soil groups. Mehlich 3 can be applied for extraction of boron (B) and, in some cases, copper (Cu) and manganese (Mn).

“…Both single and sequential extraction procedures have been used to estimate the distribution and availability of Cu in soils ( Guan et al, 2011). The single extraction is convenient to perform ( Soriano‐Disla et al, 2010), but the sequential extraction technique provides more detailed information on Cu fractionation as well as the actual and potential transport of different chemical forms ( Tessier et al, 1979; Doelsch et al, 2008). In soil matrix, Cu can be associated with soil components and exist in various chemical and physical forms including soluble and exchangeable Cu, Cu precipitated with iron and manganese oxides or carbonates, Cu complexes with or adsorbed to organic matter, and Cu associated with clay minerals ( Ahumada et al, 2009).…”

Rhizosphere processes have a major impact on copper (Cu) availability and its fractions in soils. A greenhouse experiment with wheat was performed to investigate availability (using seven chemical procedures) and fractionation of Cu in the rhizosphere of ten agricultural soils (Typic Calcixerepts) amended with sewage sludge (1% w/w) using rhizoboxes. The results show that available Cu concentrations in rhizosphere soils were significantly (P < 1%) lower than in bulk soils. In comparison with the bulk soils, in the rhizosphere soils the concentration of Cu associated with organic matter and residual Cu increased by 24 and 4%, respectively, whereas exchangeable Cu, Cu associated with iron-manganese oxides, and Cu associated with carbonate decreased by 20, 14, and 12%, respectively. Dissolved organic carbon (DOC) and Cu associated with iron-manganese oxides and Cu associated with organic matter in the rhizosphere and bulk soils were significantly correlated (P < 5%). The results show that the differences between rhizosphere and bulk soils in chemical conditions such as DOC concentrations can change the proportion of soil Cu fractions and, therefore, Cu availability for wheat in calcareous soils amended with sewage sludge. The results show that the wheat root-induced modifications of chemical and biological soil conditions do not only lead to Cu depletion in mobile soil Cu fractions, but also to modification in soil Cu fractions which are commonly considered as more stable.
