Abstract: The investigation was conducted at UAHS, Shivamogga, to know the soil physical chemical, macronutrient status in Beguru microwatershed of Tarikere Taluk of Chikkmagaluru district. Surface (103) soil samples were collected grid- wise by using cadastral map of study area and were analyzed for their fertility status. The value of pH, electrical conductivity, and organic carbon was ranged from 5.21 to 9.27, 0.035 to 0.507 dS m^-1 and 0.39 to 1.28 g kg^-1 respectively. The available N, P₂O₅, K₂O, were ranged from 150.53 to 470.40 kg ha^-1, 11.70 to 58.40 kg ha^-1, 138.03 to 472.95 kg ha^-1, respectively. The available nitrogen was in medium, phosphorus content varied from low to medium and high in potassium. The exchangeable calcium, magnesium and sulphur ranged from 2.75 to 24.25 c mol (p+) kg^-1, 1.50 to 10.75 c mol (p+) kg^-1 and 14.03 to 48.48 mg kg^-1 respectively. The exchangeable calcium and magnesium content were sufficient and sulphur content was high. Available micronutrients such as Zinc are deficient but iron, manganese and copper were sufficient in these soils of micro-watershed.
