Transport herbicidů v půdním profilu

Original language description

The herbicide Syncuran was applied on a four square meter plot using an application rte of 2,5 kg/ha active ingredient. Soil samples were taken after 119 days to study the residual chlototoluron distribution in the sol profile. HYDRUS-1D (Šimůnek et al.,1998) was used to simulate water movement and herbicide transport in the soil profile. he impact of two diferent type of adsorption isotherm equation on thesolute transport was studied. The chlorotoluron concentrations in soil water tended to be higherfor the simulation with the Freundlich isotherm then that with the model using the Langmuir isotherm. In both cse, the solution did not pass a depth of 8 cm. The simulated chlorotoluron concentrations in soil samples were higher then the observed concentrations when th chlorotoluron degradation was assumed to be in soil water only. Assumption of the solute degradation in both solid and liquid phase significantly improved the accuracy of the solution. The different character of the simula
