“…Mobility of metals increases when pH of soil decreases (Greger 1999). Soil from site 2 has slightly lower pH (6.3 in uppermost horizon) compared to soil from site 1 (pH = 7 in uppermost horizon; Kierczak et al 2016). Lower pH of soil from site 2 could promote Ni, Cr, and Co accumulation by plants from this locality.…”

“…Studied materials (parent rocks, soils, and plants) were collected from two ultramafic sites previously described by Kierczak et al (2016). We chose the Szklary Massif (site 1) and Jordanów (site 2) located in Lower Silesia (southwestern Poland; Fig.…”

“…Soil from this locality is derived from partially serpentinized peridotite under lower range of greenschist facies (serpentine group minerals; olivine; amphibole; magnetite, Cr-magnetite, chlorite and orthopyroxene) and there is classified as Eutric Leptosol (Humic, Magnesic; Fig. 2; Gunia 2000; Kierczak et al 2016). From a mineralogical point of view, soil contains (a) minerals inherited from parent rock or derived from weathering (serpentine, olivine, chlorite, talc) and (b) quartz as an allogenic mineral.…”

“…Kierczak et al (2016) have explained higher phytoavailability of Ni in soils derived from the partially serpentinized peridotite (the EDTA extraction) compared to the soils derived from the serpentinite due to fact that olivines (Nibearing phase in site 1) are more susceptible to weathering than serpentine group minerals (Ni-bearing phase in site 2). Furthermore, the authors have shown that the Ni phytoavailability is higher than Co and Cr.…”

Background and aims Ultramafic soils constitute an extreme environment for plants because of specific physico-chemical properties and the presence of Ni, Cr, and Co. We hypothesized that type of ultramafic parent rock depending on their origin affects the composition of soils and plants. Therefore, phytoavailability of metals would be higher in soil derived from serpentinized peridotite compared to serpentinite because of differences in susceptibility of minerals to weathering. Results Based on DTPA-CaCl 2 extractions, we noted that soil derived from the serpentinized peridotite is characterized by a higher phytoavailability of Ni compared to soil derived from the serpentinite. On the contrary, plant species growing on soil derived from the serpentinite contain higher concentrations of metals. Conclusions Our study suggests that the metal uptake by plants is controlled by the mineral composition of parent rocks, which results from both their original magmatic composition and later metamorphic processes. Chemical extractions show that the phytoavailability of Ni and Co is higher in soil derived from the serpentinized peridotite than the serpentinite. Surprisingly, plants growing on the soil derived from the serpentinite contain higher levels of metals compared to these from the serpentinized peridotite derived soil. This contrasting behavior is due to higher abundances of Ca and Mg, not only Ni and Co, in soil derived from the serpentinized peridotite as compared to those in the soil derived from the serpentinite. Calcium and Mg are favored by plants and preferably fill the available sites, resulting in low Ni and Co intake despite their higher abundances.
