The Latosols present the typical characteristics of the predominant Amazonian soils. Djfferences in carbon content between the first three sites is likely to be more closely related to the variation in drainage between the sites rather than topography and vegetation cover or soil parent material. The Archaeological Black Earth has contrasting characteristics in com
