Most soils found under the tropical rainforests are deficient in nutrients. This is because of the warm and humid climate. There is a high temperature and this high temperature leads to decomposition of the organic material as well as the inorganic parent material of the soil. There are frequent rains and these rains leach the decomposing material off the soil , out of the root zone quickly. So, the result is that the tropical rain forests have adapted themselves and quickly take up the nutrients and most nutrients in the tropical rain forests is stored in the vegetation.
