Q. Which Jharkhand soil is least suitable for agriculture?
Answer: Laterite soil
Notes: Laterite soil in Jharkhand occurs in hilly areas like Palamau and Singhbhum. It forms under intense weathering with high rainfall and temperature. This soil is acidic and low in fertility due to high iron and aluminum oxide content. These properties make it less suitable for agriculture without soil amendments. Other soils like red and black soils in Jharkhand support various crops such as paddy, wheat, maize, cotton, and sorghum and are generally more fertile.
