  1. Bacterial population (106 g−1 soil), Urease activity (μg NH4 + g−1 soil h−1), Dehydrogenase activity (μg TPF g−1 soil h−1). Invertase activity (mg glucose g−1 soil h−1). All values are mean ± SD of triplicate samples. Different letters denote significant differences at the 0.05 confidence level between treatments at the same exposure time
