Abstract/Description: | Distillery spent wash are commonly disposed in open drains that causes several problems including polluting aquatic system as well as deteriorating soil and water quality. Therefore, to convert this pollutant into an economical source of soil amendment, raw distillery spent wash (RDSW) was tested for its efficacy in reclaiming sodic soil. The treatment of RDSW in sodic soil showed that it affects the physico-chemical properties of the soil in such a way that it reduces especially exchangeable sodium percentage by 55.96 %, electrical conductivity by 16.36 %, exchangeable sodium by 9.61 % and pH of the soil by 17.24% over four weeks of the treatment, reflecting its potential as an efficient eco-friendly soil amendment for sodic soil. The investigation generated details on the effectiveness of the distillery spent wash to be used as a source of nutrient and soil amendment for sodic soils. |
Description: | The extent of land degradation due to salinity and sodicity is estimated at about 955 million ha worldwide (Singh et al., 2016), covering about 7% of the world’s total arable land. According to FAO/UNESCO Soil Map of the world, the total area of sodic soils including both arable and uncultivated land is 434 million ha (Khan et al., 2010). In India, about 2.5 million ha have been affected solely by sodicity (Baskar et al., 2003). It justifies the need of immediate attention to adopt efficient, economical and environmentally acceptable reclamation practices. Sodic soils are usually characterized by the predominance of sodium (Na+) and usually associated with high levels of both pH soluble salts that can create profound negative impact on chemical and physical properties of soils and plant growth. The basic principle of sodic soil reclamation is to provide a source of calcium (Ca2+) to replace excess sodium (Na+) from the cation exchange sites. Under chemical amelioration technique, several amendments such as green manure, gypsum, farmyard manure, goat manure, compost etc. can be used to either change insoluble soil calcium to soluble form or supply calcium directly, which replaces the absorbed sodium from sodic soils (Hussain et al., 2001). Distillery spent wash is usually of high acidity and contains fair amount of Ca and Mg. Therefore, distillery spent wash can be used as an organic amendment in improving physical and chemical properties of soil (Baskar et al., 2003). The objective of the study is to test the efficiency of distillery spent wash as an effective soil amendment of sodic soil. |
