WebBecause of the rapid uptake of nutrients by the plants and the leaching that occurs, latosols are quite infertile. Chemical weathering of the parent rock is very strong in such a hot, wet climate. As a result, latosols lack nutrients and only iron and aluminium remain. In many places latosols are so rich in aluminium that they are termed ... WebAccordingly the soil leaching intensity is different. Preferential water flow, caused mainly by micromorphology, determines the variety of strongly leached to moderately leached areas.

Latosols, also known as tropical red earth, are soils found under tropical rainforests which have a relatively high content of iron and aluminium oxides. They are typically classified as oxisols (USDA soil taxonomy) or ferralsols (World Reference Base for Soil Resources). It is largely correct to say that latosols are tropical soils, but the reverse is not true because there are many soils in the tropics that are not latosolic.

Webleaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer.
