Is it true that rainforests have poor soil? How do they support so much vegetation?

    Over two-thirds of the world’s rainforests, and three-fourths of the Amazonian rainforest can be considered “wet-deserts” in that they grow on red and yellow clay-like laterite soils which are acidic and low in nutrients.

    In the rainforest, most of the carbon and essential nutrients are locked up in the living vegetation, dead wood, and decaying leaves. As organic material decays, it is recycled so quickly that few nutrients ever reach the soil, leaving it nearly sterile.

    Tropical rainforest trees are well-adapted to their environment and have mastered the problem of poor soils. Since the first six to eight inches of soil is a compost of decaying leaves, wood, and other organic matter, it is the richest source of nutrients on the ground. To tap this resource, canopy trees are shallow rooted that actually grow out of the ground to form a mat on the forest floor in order to more efficiently and rapidly collect nutrients.

    Makes one think about how healthy and abundant we would grow if we would use our resources just as efficiently ! J
