Abstract :Microbial activity can be affected by herbicides when they are introduced in soil. Indaziflam is a herbicide used for weed control in vineyards, apple, peach and orange orchards that inhibit cellulose biosynthesis in plants insert ignore into journalissuearticles values(500 g active ingredient/ l);. Recommended field dose of herbicide insert ignore into journalissuearticles values(RD); containing Indaziflam insert ignore into journalissuearticles values(10 ml/ da); and its 2 insert ignore into journalissuearticles values(RD x2);, 4 insert ignore into journalissuearticles values(RD x4);, 8 insert ignore into journalissuearticles values(RD x8); and 16 insert ignore into journalissuearticles values(RD x16); times of RD were mixed with a loamy soil sampled from Cukurova University Faculty of Agriculture Vineyard insert ignore into journalissuearticles values(Adana, Turkey); in this study. These mixtures were humidified at 80% of soil field capacity and then incubated for 42 days at 28ºC for the determination of carbon and nitrogen mineralization. Effects of RD and RD x2 doses on soil carbon mineralization were similar to control and no significant difference was found between them. Higher doses of indaziflam insert ignore into journalissuearticles values(RD x4, RD x8 and RD x16); stimulated mineralization of soil carbon and there were found significant differences between control and these doses insert ignore into journalissuearticles values(P<0.05);. All application doses of herbicide showed variability in ammonium insert ignore into journalissuearticles values(NH4-N); and nitrate insert ignore into journalissuearticles values(NO3-N); contents while there were generally found no significant differences between control and RD. In general, contents of soil NH4-N and NO3-N were increased in all applications as time passed and there were significant differences between days that were measured of these contents insert ignore into journalissuearticles values(P<0.05);. Results of soil nitrogen mineralization rate were as following: 1); It was significantly decreased by only RD x2 on 11th day insert ignore into journalissuearticles values(P<0.05); 2); Higher doses of Indaziflam insert ignore into journalissuearticles values(RD x4, RD x8 and RD x16); significantly stimulated it on 26th day insert ignore into journalissuearticles values(P<0.05); 3); All doses of this herbicide significantly decreased it on 42nd day insert ignore into journalissuearticles values(P<0.05);. In conclusion, the recommended field dose of Indaziflam had no negative effect on microorganisms that play an active role in soil carbon and nitrogen mineralization. It was suggested that higher recommended field doses of this herbicide can be used as an energy source by microorganisms in a loamy soil while these doses generally decreased production of ammonium and nitrate.
