Sažetak
In Croatia, imidacloprid is most commonly used in olive growing areas against olive fruit fly. Understanding variability’s in pesticide sorption that can occur among and within the regions, can improve imidacloprid applicability. Therefore, experiments were conducted to examine the relationship between selected soil properties, imidacloprid concentration and soil sorption coefficients for soils among and within two Croatian regions. The linear and the Freundlich model adequately described the imidacloprid sorption. In all soils, a greater sorption occurred at lower concentrations of imidacloprid. Better sorption was observed in soils with higher organic carbon and clay content, but organic carbon content was predominant factor influencing sorption. Thus, for soils with lower sorption capacity a greater potential mobility of imidacloprid in the soil profile is expected, indicating a need for regular monitoring and strategy development against groundwater pollution.
