    Abstract: Biochar is a relatively recent term used to denote charcoal used as an agricultural input into soils. The idea comes from the use of charcoal in the Amazon on deep, highly leached, and infertile soils by Amazonian peoples in pre-Columbian times. Biochar differs most significantly from charcoal in its primary use; rather than fuel, it is primarily u... Show More
