Although sites of ADE, also known as terra preta (TP), are not uniform in size, occur at differing distances from the markets, and vary in physico-chemical characteristics within and between sites, some generalizations regarding land uses and management are possible. We propose to examine the most common land uses associated with ADE, describe the principal management methods, and explain whether variations in use and management exist according to market access. The understanding of how present-day farmers utilize the ADE for food, fiber, and other purposes, and the strategies to produce them may offer valuable insights on the intensity of use, future contribution of ADE for the rural economy of Amazônia, and the question of sustainable management of the region?s soils.  aAmazonia  aManejo do Solo  aSolo  aUso da Terra  aBrasil1 aYAMAMOTO, S.1 aMATSUMOTO, E.1 aNAKAMURA, S.1 aFALESI, I.
