Impact of vegetable oil mill effluents on soil characteristic in Bundi district, Rajasthan, India
Durgalal Regar, Poonam Jaiswal
Industries play a major role in polluting the water bodies and soil by discharging a large amount of untreated industrial wastewater as effluent which generally have high amount of suspended solids, dissolved solids, BOD, COD, chloride, sulphate, nitrates, calcium and magnesium. The continuous use of these effluents for irrigation affects the soil properties as well as crops. In the present study, physico-chemical parameters of soybean and mustard oil mill effluent and its effect on soil properties was determined with an objective to find out the concentration of vegetable oil mill effluents that can be used for irrigation. After treatment of the effluents pH, total suspended solids and COD is brought down to permissible limit for irrigation. The change in soil macro and micronutrients level is manageable nearer to reference values of these nutrients for irrigation purpose only at very low concentrations. Thus soybean and mustard oil mill effluent can be used at with irrigation water in very low concentrations but the contribution of OME in irrigation in agriculture on large scale must be evaluated for economic viability.
