Editing Oxisol (section)

==History==
Scientists originally thought that the heavy vegetation of tropical [[rain forest]]s would provide rich nutrients, but as rainfall passes through the litter on the forest floor the rain is [[acid]]ified and leaches [[minerals]] from the above soil layers. This forces plants to get their nutrition from decaying litter as oxisols are quite infertile due to the lack of organic matter and the almost complete absence of soluble minerals [[Leaching (chemical science)|leached]] by the wet and humid [[climate]].
