Tropical soils typically exhibit characteristics such as high levels of weathering and leaching due to the warm, humid climate. They often have low nutrient content, particularly in terms of nitrogen and phosphorus, because heavy rainfall washes away essential minerals. Additionally, tropical soils, like laterites, can be rich in iron and aluminum oxides, giving them a distinct reddish color. These soils are generally more fertile in areas with dense vegetation that contributes organic matter through decomposition.
Bauxite is typically found in tropical or subtropical regions where there is significant weathering of aluminum-rich rocks. It is commonly found in soils with a high content of aluminum minerals, such as laterite soils. These soils are typically acidic and well-drained, allowing for the accumulation of bauxite deposits.
Tropical rainforest soils, such as laterite soils, can develop in areas with high temperatures and rainfall. These soils are typically highly weathered and leached, resulting in lower fertility and mineral content.
No, they do not. They are "old soils" and contain very few nutrients.

Laterite soils are most commonly found in tropical and subtropical regions with high temperatures and heavy rainfall. These environments are conducive to the intense weathering processes that lead to the formation of laterite soils.
Areas with heavily leached soils, usually in tropical or previously tropical areas.

generally infertile tropical soils
The soil type is known as Ultisols. Ultisols are highly weathered soils that form in humid tropical and subtropical regions with high temperatures and high rainfall. These soils are typically acidic, low in fertility, and have a clay-rich mineral composition.
It is a mixture between latish soil (of the tropical regions) and siernozem (desert).
Savanna soil types are typically a mix of sandy soils with some clay content. They are often nutrient-poor and well-drained, making them characteristic of dry tropical regions with a distinct wet and dry season. These soils are typically unsuitable for extensive agriculture without proper management and input of fertilizers.
