All India Soil and Land Use Survey, I.A.R.I., Nagpur, M.P.
Widely different soils following sequences of geomorphic components have been recognized and arranged in two catenas in lower lb watershed covering parts of the districts of Sundergarh and Sambalpur in Orissa State.
Topographic variations regulate hydrological conditions modifying soil climate as locally arid or locally humid which, in turn, influences pedogenic processes. Morphological features like depth, colour distribution of clay in profiles, etc. and also physico-chemical properties of different members of these two catenas distinctly indicate the heterogenety in soil development and reflect direct relationship with different hydrological conditions modifying soil climate due to topographical variations, while overhead climate and parent materials are of subsidiary values.
