Genesis and pedo-chemical characteristics of karail black clayey soils in the Lower Gangetic Basin of Uttar Pradesh-Jour

, : Genesis and pedo-chemical characteristics of karail black clayey soils in the Lower Gangetic Basin of Uttar Pradesh-Jour. Indian Soc Soil Sci 4(2): 65-71

A study has been made of the morphological, mechanical, chemical and physicochemical characteristics of a group of black clay soils, popularly known as karail, occurring in the lower Gangetic basin in Uttar Pradesh. These soils are admittedly quite distinct from their zonal associates developed under similar environments on the Gangetic alluvium and show greater resemblance with the mar of Bundelkhand or regur of Central India so as to merit their grouping under a different catenary sequence. In fact, they possess a parent material similar to the well-known black cotton soils. Their formation is attributed to a transported basaltic type of alluvium received by the Ganges from the rivers coming from the Bundelkhand region. The combined influence of climate, topography, and drainage on the parent material is discussed to account for their distinctive morphological characters.
