“…The increased IR and AWC in Y2 as compared with Y1 in this experiment suggests improved soil physical properties, probably due to desodification that resulted in increased water permeability in plots receiving the amendments. Similar findings have also been reported (Hyas et al, 1997;Wahid et al, 1998 andSahin et al, 2002) in related studies involving the use of organic and inorganic amendments on salt-affected soils.…”

“…A total of 45 cm of leaching water was applied to each column with three portions as an intermittent ponding (3 Â 15 cm). Each consecutive application of water was performed at 24-hour intervals, allowing the applied water to fully infiltrate into the soil column (Sahin et al, 2002). The leaching water had no salinity or sodicity problem and had an electrical conductivity (EC) of 0.269 dS m À1 and a sodium adsorption ratio (SAR) of 0.28.…”

Reclamation of saline sodic soils is a main problem at most of arid lands. Improving soil properties with waste materials has been investigated earlier but the effect of these materials on saline sodic soils is not fully known. A fly ash and sewage sludge mixture was applied to saline sodic soils with the intention of soil reclamation and eco-friendly waste recycling. Fly ash and sewage sludge mixtures were applied at a ratio of 1:1 to soils with three different levels of electrical conductivity (EC) and exchangeable sodium percentage (ESP) (soil I: 4.27 dS m À1 , 6.09%; soil II: 73.20 dS m À1 , 51.03%; soil III: 38.2 dS m À1 , 86.2%) at 3 different doses, that is, 40, 80, and 120 t ha À1 . Saturated hydraulic conductivity and porosity generally increased in all the soils tested, whereas bulk density and pH decreased. ESP and EC values of the amended layers decreased considerably with the application of increasing doses of waste material. These results indicate that when properly applied, two industrial residues, sewage sludge and fly ash, that are associated with a negative environmental impact, can be recycled allowing for the cheap reclamation of barren saline sodic soil.

“…Nevertheless, application of gypsum alone, while being successful in improving soil properties significantly, does not have much effect on soil physical properties. Several researchers have also reported inability of gypsum to improve physical and biological properties of soil (Sahin et al 2002). Infiltration rate increased from 4.10 mm/day to 18.20 mm/day.…”

“…High pH associated with sodic soils reduces solubility of certain nutrients causing nutrient deficiencies. Amelioration of these soils by replacement of sodium ions from the soil cation exchange site necessitates application of chemical amendments (Sahin et al 2002).…”

Effect of organic and inorganic amendments on amelioration of sodic soil and sustaining rice (Oryza sativa)-wheat (Triticum aestivum) productivity

Management of degradation of sodic lands in arid and semi-arid regions is a global concern. Amelioration of these soils through chemical amendments like gypsum or phosphogypsum is a costly affair for resource poor farmers having sodic lands. Combined use of municipal solid waste (MSW) compost with chemical amendments can providea realistic solution for ameliorating sodic soils and sustaining crop productivity. A field experiment was conducted during 2015 to 2016 at Shivri, Lucknow on highly sodic soil [pH 9.8, exchangeable sodium percentage (ESP) 78, organic carbon (OC) 1.30 g/kg and gypsum requirement (GR) 15.2 t/ha] to evaluate the influence of organic and inorganic amendments on amelioration of sodic soils and sustaining productivity of rice (Oryza sativa L.)-wheat(Triticum aestivum L.) cropping system. The treatments consisted of T1: Gypsum (G) @ 50%GR, T2: Phosphogypsum (PG) @ 50%GR, T3: G @25%GR + on-farm MSW compost @10 t/ha, T4: PG @25%GR+ on-farm MSW compost @10 t/ha, T5: G @12.5%GR + on-farm MSW compost @10 t/ha + pressmud (PM) @10 t/ha, T6: PG @12.5%GR+ on-farm MSW compost @ 10 t/ha + PM @ 10 t/ha, T7: G @ 25%GR + industrial processed (IP) MSW compost @10 t/ha and T8: PG @ 25%GR + IP MSW compost @10 t/ha. The results indicated that, application of reduced dose (25% of GR) of gypsum (T3) in combination with on-farm MSW compost @10 t/ha reduced about 14% ESP and increased 11% soil bulk density, 54% infiltration rate, 10% soil organic carbon content, and 13% available N over the recommended practice (T1). Productivity of rice and wheat crops enhanced to the tune of 4 and 12 %, respectively and thus farmers can save about ` 29444.00/ha on account of reducing the quantity of gypsum or phosphogypsum without any significant yield loss and the saved amount can be utilized to bring more area under reclamation. The maximum N content in rice and wheat grain was recorded with treatment T4.
