The results show that bacterial manure increases soil biochemical reaction thereby enhancing soil enzyme activity. Soil respiration rate, ammonification and nitrification intensity, as well as catalase (CAT) activity under bacterial manure treatment are significantly (P0.05) higher than those under the control.
