Abstract: The field investigation in relation to "Effect of organic inputs on chemical properties of soil under certified organic farms in Nagpur district†was carried out during kharif - rabi season of 2017 - 18 at the certified organic farmer’s fields of Nagpur district. Soil samples of 0-20 cm depth were collected randomly after the harvest of crops from six locations viz., Selu, Kalmeshwar, Gangner, Saoner, Chacher and Chinchbhavan of Nagpur district were selected. The certified organic farmers applying FYM @ 2.5 to 10 t ha-1, Ghanjivamrut 500 kg ha-1 and Jivamrut 500 lit ha-1 from last 7 to 17 years for different crops. The results revealed that soil pH was reduced and electrical conductivity of soil (0.215 to 0.316 dS m-1) remained almost unchanged due to incorporation of organic and inorganic sources. The application of organic inputs increased organic carbon by 2.47 to 46.48% and maximum available N content of soil by 2.08 to 44.18% over the application of fertilizers alone. The available P content of soil after harvesting of crops varied from 15.26 to 30.00 kg ha-1 and comes under medium to high range categories. The application of organic sources from 7 to 17 years decreased soil available potassium by 1.26 to 11.95% over inorganic. The variation in available sulphur (11.03 to 14.61 mg kg-1) was observed and it found low to moderately high amount in all locations. Correlation matrix observed that N, K, Cu and Mn maintained positive relationship with the yield of mandarin crops. Whereas EC, OC and N were positively correlated with yield of rice crop.
