| Abstract: | Background, aim, and scope Atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) is one of the most widely used herbicides for broadleaf weed
and certain annual grass controls and is popular because of its effectiveness and low cost. Losses of atrazine from agricultural
lands into adjacent surface water and underlying groundwater have raised public concerns. Several computer models have been
developed for atrazine runoff in watersheds. One limitation for most of these models, however, is that vast amounts of input
parameters are required for simulations. These input parameters are sometimes difficult to obtain through the experimental
measurements for model calibrations, validations, and applications. Therefore, a need exists to develop a simple and yet a
realistic modeling tool that can be used for effectively investigating atrazine dynamics in agricultural soils. This study
was designed to meet this need. |
