Soil-to-plant transfer of native selenium for wild vegetation cover at selected locations of the Czech Republic
Total selenium (Se) contents were determined in aboveground biomass of wild plant species growing in two uncultivated meadows at two different locations. The soils in these locations had pseudototal (Aqua Regia soluble) Se in concentration ranges of between 0.2 and 0.3 mg kg−1 at the first location, and between 0.7 and 1.4 mg kg−1 at the second location. The plant species represented 29 plant families where the most numerous ones were Poaceae, Rosaceae, Fabaceae , and Asteraceae. The selenium contents in the plants varied between undetectable levels (Aegopodium podagraria, Achillea millefolium, Lotus corniculatus) and 0.158 mg kg−1 (Veronica arvensis, Veronicaceae). The Se levels were roughly one order of magnitude lower compared to other elements with similar soil content, such as cadmium and molybdenum. The transfer factors of Se, quantifying the element transfer from soil to plants, varied between <0.001 and 0.146 with no significant differences between the locations, confirming the limited soil-plant selenium transfer regardless of location, soil Se level, and plant species. Among the plant families, no unambiguous trend to potential elevated Se uptake was observed. Low Se content in the soil and its plant availability was comparable to other Se-deficient areas within Europe.
