Assessment of carbon fraction was undertaken in Nandipura mini-watershed area under different land-use systems. Eight land-use systems were selected viz; agricultural system (maize, ragi and groundnut), horticulture system (arecanut, coconut and pomegranate), fallow land and scrubby land for the study of dynamics of carbon. Among the different land-use systems, horticultural land use systems recorded significantly higher potassium dichromate oxidizable carbon (PDOC), potassium permanganate oxidizable carbon (PPOC), Cold water extractable carbon (CWEC), soil microbial biomass carbon (SMBC), Total organic carbon (TOC), Total inorganic carbon (TIC) and Total Carbon (TC) at three depths of soil (0-20 cm, 20-40 cm and 40-60 cm) followed by agricultural land-use system. Significantly higher carbon stock was recoded under arecanut land-use system (30.95 t C ha-1) at surface depth and least carbon stock was recorded under maize land-use system (17.29 t C ha-1). Similar trend was observed at subsurface layers.
