    The study was carried out to know the fertility status of soils of Bhudargad tehsil, Kolhapur district by using GPS-GIS technology and to correlate soil properties with the available nutrients and to evaluate the fertility index of Bhudargad tehsil during the year 2015-2016. The pH of soils of Bhudargad tehsil varied from 5.5 to 8.0, most of the soils found to be moderately acidic (50.67%) while EC varied from 0.02 to 1.48 dS m-1, the soils found to be normal (96 %). The calcium carbonate content varied from 0.5 to 2.8 per cent, the area was slightly calcareous (61.33%) to moderately calcareous (28 %). Organic carbon content varied from 0.26 to 1.32 per cent and categorized as Very high (6.67%), High (33.33%), Moderately high (40%), Moderate (13.33%) and Low (6.67%). The soil available nitrogen, phosphorus and potassium ranged from 141.30 to 348.10, 7.16 to 28 and 100.20 to 300.0 kg ha-1, respectively.The 57.33% soils were low and 42.67% were moderate in available nitrogen, while in respect of available phosphorus 17.33% soils were low, 40% moderate and 42.67% moderately high. In case of available potassium 15.33% soils were low, 6.67% moderate and 51.33% moderately high. The exchangeable calcium and magnesium ranged from 6.50 to 48.50 and 1.0 to 19.50 cmol (p+) kg-1, respectively. The exchangeable sodium ranged from 0.21 to 2.0 cmol (p+) kg-1. The available sulphur varied from 5.14 to 14.97 mg kg-1. The soils were low (66%) to moderate (34%) in available sulphur content. The DTPA extractable iron, manganese and copper were found to 100 % sufficient except zinc (27.33%) deficient in Begawade, Pangine, Pal, Ranewadi, Anap B.K, Kudtarwadi villages respectively. The pH was significantly and positively correlated with exchangeable calcium,magnesium and potassium. EC was significantly and positively correlated with calcium and potassium. The organic carbon was significantly and positively correlated with nitrogen and copper. Calcium carbonate was significantly correlated with potassium, calcium and magnesium. The fertility index of Bhudargad tehsil for organic carbon, available nitrogen, phosphorus and potassium was medium (2.10), low (1.21), low (1.62) and medium (1.94), respectively.
