The biochar that results from these activities persists in the soil. Long after the first production of biochar, farming societies emerged, and farmers often noticed the favorable effects of biochar for agriculture. Whether farmers then began to intentionally produce biochar for soil amelioration, and if so, when such intentional production of biochar began, are subjects of debate. Traditional practices that result in the production of biochar and its accumulation in soil will be reviewed. It will be shown that long before the recent interest in biochar research and development, societies in many parts of the world produced biochar-enriched soils, and some of them exploited the benefits of these soils for agriculture. aBiochar aSoil amendments aCondicionador do Solo1 aMCKEY, D.1 aGIANI, L.1 aTEIXEIRA, W.
