Laterite soils are formed in tropical and subtropical regions with high rainfall. The prolonged leaching process due to heavy rainfall removes soluble nutrients, leaving behind iron and aluminum oxides. The warm and humid climate accelerates the weathering of parent rock material, contributing to the formation of laterite soil.

Another name for red soil is laterite.
Laterite soil is found in the western coastal region due to the warm and wet tropical climate, which accelerates the process of leaching and weathering of rocks. The heavy rainfall and high temperatures in the region contribute to the formation of laterite soil by promoting the breakdown of parent rocks rich in iron and aluminum.
Laterite soil is characterized by high levels of iron and aluminum. When it rains, these elements dissolve in the water and are leached downward because they are not retained in the soil due to its low clay content. This leaching process can lead to soil infertility and nutrient depletion in laterite soils.
Paalai soil is called laterite soil in English.
The rate of percolation in laterite soil can vary depending on factors such as soil composition, structure, moisture content, and porosity. Generally, laterite soils have a moderate to high rate of percolation due to their porous nature and ability to drain water quickly.
