Pedological investigation carried out on a soil toposequence of Bastar Plateau in Kanker district of
Chhattisgarh state and landform-soil relationships were established. Five soil profiles, representative of the
summit, shoulder slope, pediments and upper and lower pediplains in a toposequence were studied. The
study indicated that the soil development and its properties were following the toposequence. The profile
development was least at the summit and best in the pediplains of the toposequence. The horizon sequences
observed were Ap-Cr, Ap-Bw-BC, Ap-Bw-Cr and Ap-Bw-Bss from summit through the pediplains. The
soil colour varied from reddish to dark gray down the toposequence. The solum depth varied from extremely
shallow to very deep. An increasing trend was observed in clay content, cation exchange capacity, soil
reaction, electrical conductivity, base saturation, and exchangeable cations from summit through the
pediplains. The soils of summit, pediments and pediplains were classified as Entisols, Inceptisols and
Vertisols, respectively.
