Titel
Herbicide transport with surface runoff
Abstract
Rainfall simulation studies are described for investigations of herbicide transport via runoff. The experiments can be carried out under defined application and rainfall conditions (e.g. rainfall intensity, rainfall duration, rainfall energy, realistic drop size distribution), on small plots with well known soil properties (e.g. soil texture, soil organic matter, surface scaling, aggregate breakdown, hydrology properties), plant cover, stone cover and topography (slope, microrelief of the soil surface). There is the possibility to produce more or less strong erosive runoff events. Non-erosive rainfall simulation studies on semi-large plots with agricultural sprinklers or with special contructed rainfall simulators are conducted. The experiment should take place on selected location sites, which should be representative of the watershed and typical of the agricultural region. The results, which are obtained by small and semi-large plot experiments, can be extrapolated on natural runoff events in the field.
