Kardinia College Trail
A comprehensive small-scale trial was implemented at Kardinia International College to investigate if biochar soil amendments have an effect on the aboveground biomass and growth response of a selection of native species indigenous to the Geelong region.

Rainfall was almost non-existent and average summer temperatures were the warmest on record from establishment (spring 2012) until autumn 2013. Addition of biochar appears to have had a positive effect on the growth response (canopy and height measurements) of Yellow Gum in this scenario. Data for Drooping Sheoak and Blackwood are encouraging with respect to seedling height, but not for canopy diameter to date (this will be monitored over time).
