Abstract: The field investigation was carried out on farmer’s field of Katol tehsil during the year 2016-17 with the objective to evaluate the soil fertility status under various nutrient management practices on farmers field of Nagpur mandarin. The five locations viz., Fetri, Katol, Katol (RFRS), Wandali wagh and Hatla were selected for recording various observations and considering the different nutrient management practices viz. Organic, inorganic and integrated nutrient management. Fifteen soil profile samples were taken from 0-30, 30-60 and 60-90 cm depth randomly selected over the field of Nagpur mandarin. The results revealed that data of soil reaction indicating moderately alkaline in nature with no much variations in electrical conductivity of soil with the practices of various organic, inorganic and integrated nutrient management. The values of organic carbon found decreased with depth and the maximum values of organic carbon in soil was observed (9.2 g kg^-1) with orchards treated with use of organic inputs. Organic carbon was observed 9.2 g kg ^-1 and 7.8 g kg ^-1with orchards aged eight treated with use of 15 kg FYM + 332:140:83 g NPK tree^-1 and 20 kg FYM + 171:125:83 g NPK tree¹, respectively. Fertility status of soils was maintained with the application of various organic liquids alone or in combination of FYM, inorganic fertilizer and integrated manner. The use of FYM, manurial liquid and solid organic sources was found useful in maintaining the soil available micronutrient status of orchards of Nagpur mandarin of area of Katol tehsil.
