Characterization of soils of Diara land occurring in Gangetic plains of Bihar

The soils of Diara land occurring in alluvial fans and flood plains are young and stratified with AC profiles. They are characterized by light colour, sand to sandy loam texture, single grain to massive structure, slightly alkaline reaction, low CEC and high base saturation. They are found to be highly siliceous and low in iron and aluminium oxides. The variation in CaO and K2O contents is attributed to the nature of parent materials. These soils have very faint and poor pedogenic manifestations as seen in their morphology. These soils have been classified as Typic Ustifluvents.
