Abstract

Laboratory and field experiments were carried out with 2,4-D herbicide (2,4-Dichlorophenoxyacetic acid) to evaluate its transformation and migration in the coastal water protection zones of the Oka river, Russia. In the first laboratory experiment, the transformation of 2,4-D was studied in varioussoil samples from coastal slopes (1-0 degrees) of 480 m length soil-geochemical catena on the right side of the Oka river in comparison with watershed and floodplain soils. The transformation of 2,4-D was the lowest in soil samples with minimal pH values and was independent of either slope values or vicinity to the Oka river channel. Using indirect estimates, the surface runoff potential was calculated for this herbicide. In the second field experiment, the vertical migration and transformation of 2,4-D was carried outin soddy sand soil (Eutric Arenosol) placed in the left side of the Oka river (0-100 cm) under 'soft' (40 mm 2 hr(-1)) and 'hard' (40 mm 15 min(-)1) irrigation regimes. Furthermore, the transformation of this herbicide was studied in 0-20 and 40-50 cm soil layers under various temperature and moisture regimes. After 1 day of irrigation, the main herbicide quantity was found in the 0-30 cm layer under both irrigation regimes. The transformation of the herbicide was faster in the surface, 0-20 cm layer, than in the deeper, 40-50 cm layer.
