Abstract: The field investigation in relation to "Impact of organic inputs on physic-chemical properties of soil under certified organic farms in Nagpur district” was carried out during Kharif-rabi season of 2019 - 20 at the certified organic farmer’s fields of Nagpur district to assess the soil properties, quality and yield of different crops as influenced by various organic resources. 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 for recording various observations. The results revealed that soil pH was reduced due to continuous application of various organic sources to field. However, electrical conductivity of soil (0.289 to 0.479 dS m^-1) remained almost unchanged due to incorporation of organic and inorganic sources. The application of organic inputs increased organic carbon by 5.95 to 55.32 per cent at different locations over fertilizer applied field. The bulk density of soil decreased and hydraulic conductivity and water holding capacity increased by 1.34 to 20.46 per cent due to long term effect of various organic sources.
