Trace metal availability under different land uses (forest and agriculture)

Trace metal concentrations in soil solution represent the most available fraction of trace metals. Extraction by ultra pure water has shown to be a good indicator of soil solution concentration and trace metal availability. In present study soil solution concentration of toxic (Cd and Pb) and essential (Mn and Fe) were examined for the differences between land uses (forest and agriculture). The study was conducted in Eastern Croatia. The results indicate significant influence of land use on the water extractability of all examined trace metals except Fe. In water extracts from forest soils, the concentrations were significantly higher compared to extracts from agricultural soils for: Mn (p<0.001), Cd (p<0.001), and Pb (p<0.01) (Table 1). Such behavior of water extractable trace metals is most likely related to soil pH and DOC, since soil properties also showed significant difference among land uses (Table 1.) and several authors showed that soluble concentrations of trace metals are controlled by soil properties mainly pH, SOC and DOC (McBride et al. 1997 ; Tipping et al. 2003). These findings, in context of agroforestry, can indicate beneficial effect of using trees on agricultural land for availability of essential elements such as Mn, however, together with essential elements toxic ones (Cd and Pb) will also become mobilized and available.
