Title: In many parts of the Amazon Basin, farmers have cut down the tropical rain-fores Post by: colleen on Aug 25, 2012 In many parts of the Amazon Basin, farmers have cut down the tropical rain-forest trees and planted crops. However, the farmers often abandon these croplands after a few years and move on. What are some possible reasons for this?

Even if the trees are burned to release nutrients, the abundant rains quickly wash the "fertilizer" away.
