To better understand these processes, a runoff study was conducted to evaluate vegetated buffer strips performance in reducing atrazine, metolachlor, and chlorpyrifos transport as affected by the drainage area to buffer strip area ratio. The simulated runoff water mixed with pesticide–treated soil was distributed onto six vegetated buffer strips, each 1.52 m wide . 20.12 m long, located downslope of the inflow distribution tank in a well established vegetated grassed waterway. These strips provided for three replications of two inflow rates designated as drainage area/buffer strip area ratio treatments of 15:1 and 30:1. Infiltration for the 15:1 treatment averaged 38.8% of the inflow volume"
