Which of the following specific soil orders dominates the active floodplains and chars of the Brahmaputra River valley, characterized by stratified alluvial deposits with minimal profile development due to frequent annual deposition?

💡 Solution & Explanation

Entisols are young, newly formed mineral soils lacking distinct genetic horizons other than an A horizon, commonly found on active river floodplains, recent alluvial deposits, and shifting sandbars known locally as chars along the Brahmaputra River. Vertisols are clay-rich shrinking and swelling soils found in central and peninsular India. Oxisols are highly weathered tropical soils rich in iron and aluminum oxides. Spodosols develop under coniferous vegetation in cold, humid climates.
