Influence of the herbicides Goltix and Sencor on nitrification process in two soils
Abstract:
The effects of two herbicides, Sencor and Goltix, on nitrification in two soils were studied using a mixed culture of nitrifying bacteria. Sencor (10 ppm, 50 ppm, and 100 ppm) has no inhibitory influence on nitrification. In the presence of 50 ppm and 100 ppm Goltix the nitrification process is not affected but in the presence of 500 ppm Goltix ammonium oxidation is considerably retarded. In sandy loam field soil (pH 7.1) the retarding effect was more pronounced than in silty loamy sand (pH 7.8) of meadow. 500 ppm Goltix has a more lasting inhibitory effect on ammonium oxidation than some commercially available nitrification inhibitors.
