Abstract

The effects of different concentrations of Cd (100, 200, 400, 800 and 1600 ppm) on the activity of soil dehydrogenase enzyme and soil respiration were studied after 15 days and 30 days of incubation period. The maximum activity of soil dehydrogenase enzyme was observed at 100 ppm dose of Cd after 15 days of incubation period. Beyond this level a gradual reduction in enzymatic activity was observed. After 30 days of incubation period, all the applied doses of Cd resulted in a marked reduction in the activity of dehydrogenase enzyme, over the control. After 30 days of incubation period a negative correlation was observed between soil dehydrogenase enzyme activity and soil applied doses of Cd. After 15 days of incubation period, no significant difference was observed in soil respiration. Soil respiration was significantly inhibited in all applied doses of Cd after 30 days of incubation period. Soil dehydrogenase enzyme activity and soil respiration can be used as indicators for cadmium toxicity in soils.
