Abstract

The objectives of this study were to compare transport of Br- and PFBA under cropped and fallow conditions for a range of soil water contents and evapotranspirative demands, and to evaluate the predictive capability of a computer simulation model (LEACHM) using independent estimates of model input parameters. In 1991, a field study was conducted using in situ columns on a Brocko silt loam. The transport of two tracers (Br- and PFBA) was measured at three depths for three water regimes under cropped and fallow conditions for 60 d following chemical application. Results indicated that adequate predictions of the transport of PFBA were obtained using LEACHM when coupled with independent estimates of model input parameters.
