Abstract:

An Investigation was carried out on enzymes activity during composting of urban waste with microbial consortium and activators (cow dung slurry, diary spent wash, biodigester liquid and bovine urine). Significant variation in dehydrogenase, phosphatase and urease activity was noticed among the treatments at all the intervals during composting of urban waste with activators. Dehydrogenase activity was increased at 30th day of composting and decreased at 60th day thereafter, it gradually increased at 120th day of composting. The final stage of composting, the highest dehydrogenase activity was observed in the treatment T3 (T2+ cow dungslurry) (196 μg TPF /g soil/hour) followed by the treatment T7(T2+Bovine urine) (190.25 μg TPF /g soil/hour). The phosphatase and urease activity were found to be increased at all the intervals. The maximum acid and alkaline phosphatase activity were recorded in the treatment T7 (T2+Bovine Urine) (120 µg PNP g-1hr-1) and T3 (T2+ Cowdung slurry) (112.25 µg PNP g-1hr-1). At 120th day of composting, maximum urease activity was recorded in the treatment T3 (T2+ Cowdung slurry) (380µg NH4+-N g-1hr-1) followed by the treatment T7 (T2+ Bovine urine) (376.25 µg NH4+-N g-1hr-1). The least dehydrogenase, urease, acid and alkaline phosphatase activity was in the treatment T1 (Urban Waste) (154 μg TPF g-1 soil hr-1, 330 µg NH4+-N g-1hr-1, 71.25 and 68 µg PNP g-1hr-1respectively).
