I am part of a team (biogeochemists, plant physiologist, ecologist, soil scientist) determining horticultural and agricultural values for blended chars. Our work ranges from eco services, to phytoremediation, synergistic combinations of herbs and fruits for health and nutritional value, to rooftop conservation mimicry of specific biomes with biochar as the underlying link. I have presented papers on biochar at Build Boston and the University of Toronto.
