Q. Which soil type in Jharkhand is least suitable for agriculture?
Answer: Laterite soil
Notes: Laterite soil in Jharkhand occurs in Palamau, Gumla, and Singhbhum regions. It is acidic and low in fertility. The soil is rich in iron and aluminum oxides. Laterite soil requires heavy soil amendments for agriculture. Alluvial soil in Jharkhand is highly fertile for crops like rice, wheat, and sugarcane. Red soil is commonly found and supports crops with proper nutrient management. Smooth soil generally refers to fertile alluvial or sandy soils manageable with irrigation.
