This study was conducted to evaluate the efficiency of various inorganic and organic materials to improve physical properties of soil. Saline sodic soil (saturation percentage = 40.36%, EC<SUB>e</SUB> = 5.15 dS m<SUP>?1</SUP>, pH<SUB>8</SUB> = 8.70, SAR = 18.84 (m mol L<SUP>?1</SUP>)<SUP>1/2</SUP>, bulk density = 1.49 Mg m<SUP>?3</SUP>) was collected, brought to wire house and filled in pots after laboratory analysis for various parameters. Different sources of organic nutrients like farm manure (FM), press mud, compost, poultry manure and sesbania green manure were analyzed for their chemical composition. The experiment comprised of 12 treatments replicated thrice; T<SUB>1</SUB>: control (recommended NPK), T<SUB>2</SUB>:½ recommended NPK, T<SUB>3</SUB>: FM at 1.5% by soil weight, T<SUB>4</SUB>: pressmud at 1.5% by soil weight, T<SUB>5</SUB>: compost at 1.5% by soil weight, T<SUB>6</SUB>: poultry manure at 1.5% by soil weight, T<SUB>7</SUB>: sesbania green manure at 1.5% by soil weight, T<SUB>8</SUB>: T<SUB>2</SUB> + FM at 0.75% by soil weight, T<SUB>9</SUB>: T<SUB>2</SUB> + pressmud at 0.75% by soil weight, T<SUB>10</SUB>: T<SUB>2</SUB> + compost at 0.75% by soil weight, T<SUB>11</SUB>: T<SUB>2</SUB> + poultry manure at 0.75% by soil weight, T<SUB>12</SUB>: T<SUB>2</SUB> + sesbania green manure at 0.75% by soil weight. These treatments were applied using completely randomized (CR) design and appropriate time was given to decompose these organic nutritional sources. Seeds of wheat cultivar Sahar-2006 were sown. After harvesting the wheat, soil samples were collected from each pot and analyzed for various physical properties like bulk density, porosity and saturation percentage. An improvement in physical properties (bulk density, porosity and saturation percentage) of soil was noticed with the application of various organic nutritional sources but role of compost alone (T<SUB>5</SUB>) remained prominent.
