Summary
This laboratory soil study examined charcoal and smoke condensates, known as pyroligneous acid, in a highly weathered Amazonian Ferralsol. Charcoal increased basal respiration, microbial biomass, population growth and microbial efficiency, while pyroligneous acid caused a sharp increase in microbial activity, likely because easily degradable compounds were used by microbes.
