摘要

A special study design was established which allowed for the monitoring of soil water and solute movement without causing significant artificial effects on the transport of conservative tracers and organic compounds. The test substance glufosinate-ammonium was applied with a rate of 2 x 800 g/ha in spring under what would be considered realistic worst-case conditions in a cool climate. The special design of this outdoor field leaching study accompanied by computer modeling proved to be a sensitive and reliable method for the evaluation of the behavior of glufosinate-ammonium and its main metabolites in soil. The results of the study showed that the potential of glufosinate-ammonium and its main metabolites for leaching to ground water is negligible.
