The research work was conducted in order to get an insight about the soil physicochemical properties in central and southern dry zones of coconut growing areas of Hassan district, Karnataka during 2022-23. The soil samples from surface (0-30 cm) and sub-surface (30-60 cm) were collected under central and southern dry zones of Hassan district for the study. Soil samples collected from different agro-climatic zones were analyzed for both physical and chemical properties. The present investigation revealed that soil texture was sandy clay loam to sandy loam in surface soil and sandy clay in sub-surface depths. The soil pH was neutral to mildly acidic in soils of both the agro-climatic zones and the mean electrical conductivity value were normal. The organic carbon content in surface and sub-surface depths ranged from low to high in coconut growing soils of both the agro-climatic zones. Soil pH and electrical conductivity increased with increase in soil depth whereas, the organic carbon content decreased with depth. The average available nitrogen, phosphorus and sulphur status in surface soils of coconut gardens of study area were observed to bemedium and decreased with depth. Whereas the available potassium status was recorded to be higher and decreased with depth. Among the micronutrients, the mean available iron, manganese and copper content were observed to be sufficient where as, insufficient zinc content was noticed in the study area. The study enlightend the varied nature and properties of the coconut growing soils of central and southern dry zones of Hassan district and represented fertility status of the soils to enhance coconut palm health and productivity.
