Distribution of exchangeable Al, Fe and Mn in forest soils from two contrasting watersheds in northern Alberta, Canada
The chemical processes governing the retention and mobilization of trace elements in forest ecosystems are not fully understood. We evaluated factors affecting metal distribution in forest soils from two contrasting watersheds in the oil sands region in northern Alberta, Canada. The soils in Lake 287 were generally more acidified than those in Lake 185 based on pH and Ca. A1, and base saturations. Exchangeable AI and Fe, but not Mn, were highly correlated to organic matter content in mineral soil horizons. Exchangeable Al and Fe were also linearly correlated to soil pH in the two watersheds. The overall mobilization of Al, Fe and Mn was more evident in Lake 287 than in Lake 185.
