Description Belgavi district in Karnataka is characterized by three contrasting agro-climatic zones viz., a relatively dry
semi-arid northern dry zone (Zone-3) with low rainfall, a somewhat higher rainfall area termed transitional
zone (Zone-8) nestling between the Western Ghats and Eastern Plains, and a heavy rainfall area comprising
part of Western Ghats called hilly zone (Zone-9). This situation provided an opportunity to compare the
properties of pedons occurring in these agro-climatic zones. Nine pedons, three each from the three microwatersheds
viz., Yadawad (Zone-3), Hukkeri (Zone-8) and Khanapur (Zone-9) were characterized for their
morphological, physical and chemical properties with an objective of comparing their properties which
have an implication on their use and behaviour. Pedons from Yadawad micro-watershed (Zone-3) were
deep, alkaline, calcareous and contained considerable amount of salts and are rich in clay content. The
pedons of Hukkeri micro-watershed (Zone-8) were shallow to moderately deep, neutral, non-calcareous
and contained low amount of salts and are somewhat coarse textured. Despite similar parent rock (basalt) in
these two micro-watersheds, the variation in depth and texture are a direct result of erosion and deposition
due to topographic variations. The pedons from Khanapur micro-watershed (Zone-9) were acidic, highly
leached, and moderately fine textured. The variation in the soil properties of soils of Khanapur watershed
sharply contrasted with soils of both Yadawad and Hukkeri watersheds due to high rainfall at the former
compared to the latter. The soils of Yadawad micro-watershed classify as Typic Calciusterts, those of
Hukkeri micro-watershed as Lithic and Typic Ustorthents and the soils of Khanapur micro-watershed as
Oxic Dystrustepts and Kanhaplic Haplustalfs reflecting the leaching regime and erosion of sediments
during soil formation.
