Enhanced weathering pilots at Haliburton Forest

SMALL PLOT TRIALS IN HALIBURTON FOREST TO QUANTIFY CO2 REMOVAL RATES

To better assess CO2 removal rates using different doses of wollastonite in Haliburton Forest soil, a team led by Ian Power and Shaun Watmough, and postdoctoral fellow Minger Guo set up 16 small plot trials in Haliburton Forest, Ontario. The plots are equipped with tension and zero-tenson lysimeters, moisture probes, and weather station to closely monitor changes in soil water chemistry.

This experiment aims to provide a more accurate quantification of CO2 through the enhanced weathering of wollastonite in the acidic forest soils, with other variables controlled. Additionally, this study will evaluate the pH regulation and calcium supplementation by wollastonite as part of testing the overall impact on the forest health in acidic and calcium-deficient North American forest soils.

Thanks to everyone’s hardwork!
