Abstract: An experiment was conducted at the field of Department of Soil Science and Agril. Chemistry, JNKVV, Jabalpur (M.P) during kharif and rabi season of 2015-2016 under All India Co-ordinate Research Project on “Long term Fertilizer Experiment” in simple randomized block design with eight treatments and four replications comprising viz., T₁ (Control) T₂ (50 % NPK), T₃ (100 % NPK), T₄ 150% NPK), T₅ (100%NP), T₆ (100%N), T₇ (100%NPK+FYM), T₈ (100%NPK-S). The results obtained from the present investigation clearly indicated that physical properties (bulk density, infiltration rate, moisture content, fractions of different sized aggregates and mean weight diameter) of soil were significantly affected by long-term application of integrated nutrients under soybean-wheat cropping system. It was found that integration of FYM increased the beneficial effect on physical properties over the treatments of inorganic nutrients application alone in both surface (0-15 cm) and sub-surface (15-30cm) soil under soybean-wheat cropping system.
