Detailed explanation-1: -The alluvial soil varies in nature from sandy loam to clay. They are rich in potash but poor in phosphorus. 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.
Detailed explanation-2: -Sediment that is deposited on floodplains and deltas by rivers and streams during seasonal flooding is called Alluvial soil.
Detailed explanation-3: -Alluvial soils are formed mainly due to silt deposited by Indo-Gangetic-Brahmaputra rivers. In coastal regions some alluvial deposits are formed due to wave action. Rocks of the Himalayas form the parent material. Thus the parent material of these soils is of transported origin.
