Abstract :This work was carried out to determine the effects tree herbicides insert ignore into journalissuearticles values(Trifluraline, 2,4–D and Knock Out); on the micro-biological nitrification in two soil samples. The soil samples were collected from the agricultural lands of Bahri Dağdaş Experimental Station and Selçuk University Campus, Konya, and they were silty clay and sandy – clay loam in the tex-ture, respectively. The herbicides were applied to the soil samples at five different levels insert ignore into journalissuearticles values(0 – 200 – 600 – 1200 – 4800 mlda-1); and at six different incubation periods insert ignore into journalissuearticles values(0 – 4 – 8 – 12 – 20 – 40 days);. The results can be summarized as follows; It was found that the most effective herbicides, to increase the microbio-logical nitrification, were Knock Out and Trifluraline at the levels of 4800 mlda-1 in Bahri Dağdaş silty clay, and 200 mlda-1 in the Campus sandy clay loam soil samples, respectively. It was concluded that, the herbicides showed a general tendency to increase nitrification of the soil samples.
