Catenary Relationship Existing Among the Soils of the Lower Vindhyan Plateau in Uttar Pradesh

Pedo-chemical studies conducted on the soils of lower Vindhyan Plateau in Mirzapur district (Uttar Pradesh) have revealed well defined catenary relationships, and increasing drainage intensity down the slope accompanied by colour and textural variations. Soils of the first catena are lighter in texture, slightly acidic in reaction, richer in silica, poorer in sesquioxides as also in calcium and magnesium as compared to soils of the second catena developed on limestone and shales. Soils of the upland and terraces are classified as Alfisols whereas those of lowland as Inceptisols in both the catenas of lower Vindhyan plateau.
