Question

give reason why the land in the amazon basin face loss of fertility​

Answer 1

Explanation:

The key point in deforestation of the Amazon came when colonists established farms in the forest in the 1960s. They farmed based on crop cultivation and used the slash and burn method. The colonists were unable to successfully manage their fields and the crops due to weed invasion and loss of soil fertility.

Answer 2

Answer:

Once the land is cleared of rainforest vegetation the soil is left bare. When it rains, the nutrients in the soil are washed away.  The soil is no longer able to support plant life because it is not fertile. The roots of plants and trees no longer hold the soil together so it is easily eroded.
