Short summary
Boreal forest soils store approximately one third of forest soil carbon globally. Stabilization of organic carbon in these soils is largely controlled by reactive aluminum content derived from parent material, which in boreal regions is typically glacial till. We used a Random Forest approach to predictively map and model reactive aluminum and its uncertainty in glacial till across Newfoundland. This supports future modelling efforts and estimates of the soil carbon reservoir in boreal forests.
