Enhanced rock weathering (ERW) can be implemented in managed forests that use selective harvesting through trail networks for carbon dioxide removal (CDR) while improving soil health by neutralizing excess acidity and restoring base cations. Wollastonite-rich rock powder (Wo = 28.4 wt% and D50 = 350 μm) was applied using a tractor and spreader from a trail in Haliburton Forest, Ontario, Canada, to evaluate the practicability and challenges of incorporating ERW into silviculture practices. The intended amendment dosage of 5 t/ha aimed to replace soil Ca losses due to historic acidic deposition.
