How thick on average is the topsoil in tropical rainforests?

    The top soil in rainforests is not as thick as one might think.  In the Rio Dulce, it is only about 12 inches deep.  The dead matter is recycled and reused so quickly in the rain forest to support the vast biological activity, that there is no need to have a very deep top soil.  While there is lots of dead organic material feet below the surface, only about 10 or so actual inches are useful topsoil.
