The morphological, physical and physico-chemical characteristics of soils in Sollapura sub-watershed of Chikmagalur district in Karnataka have been studied. The district comprises of 7 taluks of which Tarikere comes under southern transition zone. Tarikere talu have wide range of climate variation from perhumid to semi-arid. The study revealed that the soils had colours in the hue of 10YR to 5 YR, well to poorly drained, slightly acidic to moderately alkaline, low to high in organic carbon and low to medium in cation exchange capacity with wide textural variations. The soils on gently sloping topography exhibit the development of argillic horizon (Bt). The soils have been classified as Alfisols soil order and Ustalfs at suborder level due to the presence of ustic soil moisture regime. On the basis of the major soil constraints, sustainable land use plan for the micro-watershed has also been suggested for their better management.
