Detailed explanation-1: -Two different types of alluvial soils have developed in the Upper and Middle Ganga plains – Khadar and Bhangar. Khadar is the new alluvium and occupies the flood plains of the rivers. Khadar is enriched with fresh silt deposits every year.
Detailed explanation-2: -Alluvium consists of silt, sand, clay, and gravel and often contains a good deal of organic matter. It therefore yields very fertile soils such as those of the deltas of the Mississippi, the Nile, the Ganges and Brahmaputra, and the Huang rivers.
Detailed explanation-3: -Alluvial soil is also known as riverine soil because it is found in river basins and is formed when the velocity of streams and rivers slows. Alluvial soil is formed by the deposition of sediments carried by rivers starting from the mountains (its origin).
Detailed explanation-4: -The Indian council of Agricultural Research (ICAR) set up an All India Soil Survey Committee in 1953 which divided the Indian soils into eight major groups.
