Is tropical soil infertile

Answer 1

Yes, this answer covers rain forests, which indeed have tropical soil. Rain forests are known for their large amount of rain fall. This results in poor soils due to the leeching of soluble nutrients. The deeply weathered ground creates infertility. Rapid bacterial decay prevents humus from forming. The concentrations of iron and aluminum oxidize and can produce mineral deposits. The only reasoning for high plant variety and density in infertile soil is because of the organic matter decay the plants will absorb, and the heavy humidity and rainfall, provide the certain plants with what they need, even in infertile soil, they just evolved that way. They evolved to not depend so heavily on the infertile soil but more on other methods such as the mineral deposits I mentioned before, and when they evolved this way, the environment that they evolved to live in are very providing to these plants resulting in the high density forests we see today.
