Abstract
The goal of this research was to obtain field data for the calibration of the module of a regional water quality model, which describes the processes of pesticide transport to open water on a field scale. To achieve this objective a field experiment was set up on the experimental farm "Kooyenburg". The soils belong to the haplorthod great group and are formed in holoceen sandy wind deposits. Boulder clay occurs at a depth of 60-100 cm below the soil surface and it's low permeability gives rise to a perched water table in wet periods in fall, winter and spring. The pesticides studied are metamitron and MITC. During the period May 1989 - April 1990 soil and water samples were taken at several places in three fields. The results indicate that MITC is transported through soil and reaches open water via drains. It cannot be excluded that metamitron is leached as well.<br>
