Abstract: Arecanut is the major commercial crop of Karnataka having root in fifteen districts. Most of the traditional areca growing soils are acidic in nature while non- traditional areca growing soils are alkaline in nature. Arecanut productivity is affected by many reasons, out of which soil nutrient imbalance is one of the important productivity constraints. A detailed soil survey was undertaken with the aim of evaluating physico-chemical properties of arecanut gardens in Channagiri, Honnali, Harihara and Davanagere taluks of Southern transition zone of Karnataka. A total of fifty samples were collected from surface (0-15 cm) and sub-surface soils (15-30 cm) and analyzed for pH, electrical conductivity, organic carbon, exchangeable calcium and magnesium and cation exchange capacity by using standard analytical methods. Study revealed that soils are sandy loam to clay in texture, acidic (slight to moderate) in soil reaction and non-saline in nature, medium to high in organic carbon content and low in cation exchange capacity.
