The pit and the earthmound methods have been studied by many researchers in the last century (1). ) of the IX - 20- charcoal produced in those kilns varies between 65 % and 80 %, the yields rarely exceeding 15 % based on the weight of the dry fuelwood charge. Statements that the recovery rate of a charcoal pit or an earthmound operation is "well over 20 %" must be regarded as unfounded.
