Question Hi,
For my AP Biology summer assignment I was asked to find an expert to answer a question about a biome of my choice. I've chosen the tropical rainforest, and my question is: is the soil in the rainforest extremely fertile or not, and why. I hope that you are able to answer this question. Thanks a lot for your help! -Tyler
Answer Tyler,
Well, that all depends on what we're talking about here. Where a rainforest is present, usually the top foot or less of soil is very fertile. This is due to the collection of plant matter, insects, and other decomposing organisms that make a sort of "mulch" for the plants to grow in. Below that, however, in many areas are layers of clay, silt, and other soils that are impermeable to water and difficult for roots to penetrate. So if you take the rainforest away through logging or burning you'll have about a foot of good fertile soil for a few years, but without the dense population of plants dropping plant material and the insects and other organisms breaking it down to make "mulch", you won't have good soil for very long.
