Laterite soils are found in Madhya Pradesh, Odisha, Maharashtra, West Bengal, Andhra Pradesh, Telangana, Karnataka, Tamilnadu and along the top slopes of peninsular mountains. Tapioca, cashew nuts, Ravi, sugarcane, tea, coffee, eucalyptus are cultivated.
These soils are formed in high Rainfall and humidity regions. This soil contains high acidic nature. Cultivating crops are not possible in this soil. These soils are found in Kerala.
