Abstract: Field study was conducted at Borlaug Institute for South Asia (BISA) Research Farm, Lakhnwara, Jabalpur to evaluate the changes in bulk density and nitrogen (available and total) contents of a Vertisol as affected by land use practices and depth of soil after harvest of kharif and rabi seasons of 2015-16. Soil samples were collected with the help of core auger from the fields practiced with different land uses [L1: Uncultivated, L2: rice-wheat system with conventional agriculture (CS), L3: rice-wheat system with conservation agriculture (CA), L4: soybean-wheat system with CS, L5: soybean-wheat system with CA, L6: maize -wheat system with CS and L7: maize-wheat system with CA] at 0-5 cm, 5-15 cm and 15-30 cm depths. For statistical analysis of data in split plot design land use practices were considered as main plot and depth (0-5 cm, 5-15 cm and 15-30 cm) as sub-plot treatments with three replications. It was found that bulk density was significantly affected by land use practices over soil depths with highest (1.51 and 1.49 Mg m-3) under uncultivated (L1) and lowest in maize -wheat system with CS (L6) treatments, respectively for kharif and rabi season. Bulk density of soil in 5-15 cm depth was lowest (1.36 Mg m-3) during both the seasons as compared those in 0-5 cm and 15-30 cm soil depths.
