Do tropical rainforests have subsoil?
Yes, tropical rainforests do have subsoil, which is found beneath the topsoil layer. The subsoil in these regions often contains minerals and nutrients leached from the upper layers due to heavy rainfall. However, the nutrient content can vary, and much of the nutrient cycling occurs in the surface layer, where organic matter decomposes rapidly. As a result, the subsoil may not be as rich in nutrients as in other forest types.
