Abstract

Soil microbial activities indicated by soil respiration and soil microbial biomass carbon (C-mik soil) in Ultisols soil as affecting by application of diuron herbicide and long-term fertilizers applications were studied. A factorial experiment in a Randomized Block Design with two replications was established. The first factor was dosages of diuron herbicide which are 0 mg kg-1 (without diuron) and 10 mg kg-1 (with diuron). The second factor was fertilizers applications which are without fertilizer (control), 100% chicken manures (dosage 20 ton ha-1), 100% green manures (leaves of Glyricidium sp., dosage 20 ton ha-1), 100% chemical fertilizers (300 kg Urea ha-1, 200 kg SP-36 ha-1, 100 kg KCl ha-1), combination of 50% chicken manures and 50% chemical fertilizers, and combination of 50% green manures and 50% chemical fertilizers. After treatments, soils were incubated in a dark room at 25oC. Soil respiration and C-mik soil were measured at 0, 3, 7, 14, and 28 days after herbicide application (AHA). The results showed that long-term fertilizers applications increased soil respiration and C-mik soil. A diuron herbicide application did not increase soil respiration and C-mik soil, except at 28 days AHA, soil without herbicide increased C-mik soil. There was not interaction between herbicide and long-term fertilizers applications in relation to soil respiration and C-mik soil. It was recommended to use diuron herbicide wisely as it affecting soil microbial activities.
