The investigation was conducted at UAHS, Shivamogga, to know the soil physico-chemical, macro and micronutrients status in Nicchapura-2 micro watershed of Davanagere district in the year 2014-15. 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 6.2 to 8.7, 0.11 to 0.84 dS m-1 and 3.1 to 5.6 g kg-1 respectively. The available N, P2O5, K2O, was ranged from 135 to 236 kg ha-1, 10 to 34 kg ha-1 130 to 415 kg ha-1, respectively. The available nitrogen was in low, phosphorus content varied from low to medium and high in potassium. The exchangeable calcium, magnesium and sulphur ranged from 8.1 to 38.1 cmol (p+) kg-1, 6.3 to 26.2 cmol (p+) kg-1 and 6.3 to 12.1 mg kg-1 respectively. The exchangeable calcium and magnesium content were sufficient and sulphur content was low. Available micronutrients iron, manganese, zinc and copper was ranged from 0.58 to 5.92 mg kg-1, 0.60 to 10.83 mg kg-1, 0.01 to 0.41 mg kg-1, 0.06 to 4.81 mg kg-1 respectively. Available micronutrients such as zinc and iron are deficient but copper and manganese were sufficient in these soils of micro-watershed.
