An increasing body of literature on the effects of climate change and increasing atmospheric CO2 levels on soils indicates that soil CO2 is a much more potent agent of soil acidification than has generally appreciated. These studies have observed significant increases in the solution concentrations of major cations and increases in the movement of these cations through the soil profile. Few studies have investigated the fate of trace elements in soils with elevated CO2, particularly in calcareous soils. In these preliminary studies we study the partitioning of trace elements in 5 soils with contrasting properties and compare the values to predictions obtained with Visual Minteq.
