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.
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.
