Water scarcity and increase wastewater generation are twin problem associated which needs to be addressed to derive benefit for agricultural production. In this context laboratory study was conducted to characterize the wastewater from four different sources (Ugar sugar-Ugar khurd, West coast paper mill-Dandeli, Nectar beverages-Dharwad, Domestic sewage water-UAS campus Dharwad) in north Karnataka and were compared with freshwater. Spentwash from the Ugar Sugar Works distillery was singularly different from rest of the wastewaters and was characterized by its high pH, EC, TSS, TDS, BOD, COD, total nitrogen, phosphate, potassium and sulphate concentration. The effect of the wastewaters on the dominant soils of north Karnataka (Red, Lateritic and Black soil) were evaluated in column study during March-2014 to April-2015. Wide variation in water characteristics was recorded with wastewaters studied. Urease, phosphatase and dehydrogenase activities were highest in spent wash treatment in red soil followed by paper mill wastewater in all soils. Activity of urease, phosphatase and dehydrogenase was recorded highest at surface layer and their activity gradually decreased with the depths in all the soils under different treatments.
