This booklet offers a finished evaluation of our present figuring out of those interesting soils: their foundation, houses, and administration via time. those new and multidisciplinary views by way of major specialists on Amazonian darkish Earths may perhaps pave the way in which for the subsequent revolution of soil administration within the humid tropics.

Our discussion here thus concentrates on the question of which human influences led to the formation of ADEs. One very important distinction has to be made in this respect: The fact that current scholarship confirms the human origin of ADEs by no means necessarily indicates that they were intentionally created, but this is still a possibility.
