Determination of soil catalase potential

In the present paper, it has been studied the catalatic potential of soils under the influence of sulfonilureic substances such as chlorsulfuron (20, 40, 100 g/ha), amidosulfuron (60, 120 and 300 g/ha) and tifensulfuron (60, 120 and 300 g/ha). The studies were performed in field plots and also following laboratory models. The results of our determinations allowed us to conclude that all three substances and their applied doses had no relevant influence on catalase activity from soil.
