Single and dual-permeability models of chlorotoluron transport in the soil profile

Original language description

This study present the transport of chlorotoluron in the soil profile under field conditions. The heribicide Syncuran was applied on a plot (4m2) using an applicaton rate of 2,5kg/ha of active ingredient. Soil samples were taken after 119 days to study the residual chlorotoluron distribution in the soil profile. The single and dual-permeability models in HYDRUS-1D(Šimůnek et al.2003) were used to simulate water movement and herbicide transport in the soil profile. Soil hydraulic properties and their varability were previously studied by Kutílek et al. (1989). The solute transport parameters, such as the adsorption isotherm and the degradation rate, were determined in the laboratory. Since the solute transport in the field was probably affected by preferential flow, the chlorotoluron distribution in the soil profile calculated using the single-permeability model had a different character than observed chlorotoluron concentrations. The chlorotoluron distribution within depth calculated u
