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. Latosols are red or yellowish-red in colour throughout and they do … WebThe soil is formed by mixing dead organic material with weathered bedrock. Soils in the rainforest are mainly thin and poor. Nutrient levels in the soil are low due to the leaching (washing away of nutrients) by the heavy equatorial rain.
