Migration capacity of soil-applied herbicides in peat soils of various stages of transformation was studied and assessed through the model experiment. S-metolachlor migrates marginally to layers below 2.5 cm. By day 110, the quantity of the herbicide determined was negligible. Clomazone was characterized by higher levels of migration both laterally (up to 12.5 cm deep in 40 days) and along the upper layers. Its main amount was noted in the 0–5 cm layer. Consequently, clomazone can inhibit the weeds growth from the seeds in a layer up to 5 cm.
