Abstract

In this study, the eff ects on soil carbon mineralization of diff erent doses [recommended dose (RD), ×2 RD and ×4 RD] of epoxiconazole + carbendazim fungicide suspension used for destroying the powdery mildew and yellow rust diseases in the cultivati on of wheat being a common agriculture product in Osmaniye were determined in soils before and after wheat spraying and the campus soil of Osmaniye Korkut Ata University. Carbon mineralization of three diff erent soils moistened at 80 % of the fi eld capacity were observed under controlled conditions (28 °C and 45 days) and CO₂ respiration method. At theend of the 45 days incubation period, the highest and statistically signifi cant value of cumulant carbon mineralization was observed in applied wheat soil (AWS ×2 RD). Th is value (7.756 mg C (CO₂) / 100 g) was signifi cantly diff erent in both a group and among the other groups (P <0.001). Th is result shows that epoxiconazole + carbendazim fungicide suspension added at 2 times level of the recommended dose was only used as a carbon source for microorganisms in the research soils. In the light of this fi nding, it might be said that the amount of carbon added to the soil with other doses of the chemical was not enough to increase microorganism activity.
