Herbicide losses and the influence of physicochemical properties of flufenacet, metazachlor and terbuthylazine were studied on a microplot of bare soil and slight slope with rainfall simulation. The highest concentrations were detected in the first runoff samples which decreased exponentially with further rainfall. The artificial setup of intermittent rainfall revealed that with every new rainfall event after a rainless period, a higher amount of herbicides was released from the plot than at the last interval of the previous rainfall event. This effect was caused by alterations to the soil surface that occurred during the rainless periods. Furthermore, the results show that the herbicide loss relates to herbicide adsorption to organic carbon (KOC) and herbicide solubility in water
