Abstract:

Sodic soils are characterized by adverse physical conditions with high sodium build up. These soils can be put to crop production only when they are reclaimed using calcium bearing chemical amendments. In this regard, attempts were made to study utilization of distillery spent wash to reclaim sodic soil and calcareous sodic soil. The raw distillery spent wash samples revealed that it was highly acidic (pH 4.11), with the electrical conductivity of 17.70 dS m-1. The concentration of nitrogen, phosphorus and potassium were 0.19, 0.03, and 0.88 per cent respectively and also has good amount of calcium and magnesium content of 2600 and 1700 mg L-1 respectively. In the pot experiment raw spent wash application @5.0 lakh liters ha-1 significantly reduced the pH, exchangeable sodium and ESP of soil at 30 and 60 days after application and the reduction was marginal there after upto 120 days. Application of gypsum @ 100% GR had similar effect in reducing the soil pH and ESP as that with raw spent wash application @ 2.5 lakh liters ha-1.
