What is a common misconception about soils in the humid tropics?
- Soil fertility in the humid tropics is easily maintained even after cultivation.
- Soils in the humid tropics are rich in humus because of the scarce vegetation.
- Soils in the humid tropics are uniformly poor in fertility due to the lack of vegetation. (correct)

What were the findings regarding soil fertility when forests were cut in the humid tropics for crop cultivation?
What were the findings regarding soil fertility when forests were cut in the humid tropics for crop cultivation?
- Yields were exceptionally high, indicating the high natural fertility of soils in the humid tropics.
- There was no correlation between forest cutting and crop yields.
- Soil fertility was not affected by cultivation due to the abundance of plant material.
- Yields were disappointingly low, leading to the realization that soil fertility is low and easily lost by cultivation. (correct)
