An investigation was carried out at College of Agriculture, Shivamogga during the year 2016-17 in order to know the status of potassium in soils under arecanut gardens of Davanagere district, Karnataka. For the study, 200 surface and sub-surface samples were collected from soils under arecanut garden of four taluks (Channagiri, Honnali, Harihara and Davanagere) of Davanagere district. After processing, samples were analyzed for potassium fractions. Results of the study indicated that, in surface and sub-surface soils of different taluks, the mean water soluble potassium was highest in Channagiri taluk (18.93 mg kg-1) and lowest in Davanagere taluk (10.22 mg kg-1), while the mean exchangeable potassium was highest in Channagiri taluk (127.89 mg kg-1) and lowest in Davanagere taluk (64.39 mg kg-1) and the mean non-exchangeable potassium was highest in Channagiri taluk (289.11 mg kg-1) and lowest in Davanagere taluk (137.93 mg kg-1). Similarly, the mean lattice and total potassium was highest in Channagiri taluk (3103.17 and 3539.10 mg kg-1) and lowest in Davanagere taluk (2077.11 and 2289.65 mg kg-1).
