Soil fertility and leaching losses of nutrients were compared between a Fimic Anthrosol (terra preta) and a Xanthic Ferralsol from Central Amazonia. The potential of charcoal additions among other organic and inorganic applications could to produce similarly fertile soils as these archaeological Anthrosols is assessed. Leaching of nutrients from soils where charcoal was added was significantly lower.
