>> Terra Preta - literally "black soil" Terra Preta is noble savage fiction [1] created because charcoal stains the soil quite deep. (Similar to how the OP 'spotlight' is mostly fiction) Biochar enthusiasts show the staining in soil cutouts after a few years. I do a lot of biochar (100+ liters a week) but it has mixed results in the scientific journals, meta studies don't show a lot of improvement.
