Correct Answer: Laterite soil
Solution : The correct answer is Laterite soil.
Laterite soil is found in tropical and subtropical regions, which are characterised by heavy rainfall. Heavy rainfall leaches and oxidises the upper layer of soil, making it infertile. Iron and aluminium are left in concentrated form in the upper layer of the soil because of heavy rainfall, and lime, silica, and other essential minerals are washed away. It is poor in nitrogen and phosphorus. It is rich in humus because of the presence of heavy vegetation.
