Biochar turns out to be more effective in bacteria dominant soils than in fungal, where the fungi provide some of the same services.
Tropical forests are bacterial, temperate fungal. I don’t think it’s an accident that terra preta (a biochar + ? complex of soil) is found in Brazil.
It’s also a reason we have to be careful about global warming. Temperate forests make great carbon sinks, tropical do not. If we tip more land into tropical we lose a powerful method of remediation.
