Impact of Herbicide Atrazine and Nicosulfuron on the Soil Respiration and Enzyme Activities

Abstract:

The effects of two herbicides on soil respiration, the activity of catalase and the activity of urease were studied in laboratory. The results showed that effects of atrazine and nicosulfuron on soil respiration were different. The soil respirations were in inhibition when soils were treated with atrazine, while soil respirations were in promotion-inhibition-recover when soils were treated with nicosulfuron. The soil respirations were different at different herbicide concentrations. According to coefficient of injury, herbicides atrazine and nicosulfuron both belong to low toxicity herbicides or no toxic herbicides. The effects of herbicides on the activities of catalase and urease were same, which were inhibition-recovery. The activity of unease was inhibited by atrazine and nicosulfuron before 21d. Half dosage of nicosulfuron has a significant inhibitory effect. The different concentrations of atrazine and nicosulfuron had no obvious effect on the catalase activity.
