Abstract

We evaluated a laboratory technique to isolate intrinsic processes controlling pesticide partitioning between infiltration, runoff and sediment. The laboratory technique provided controlled test conditions and reproducible results on processes affecting partitioning of rainfall, runoff, and pesticides at the soil surface, and sediment and pesticide transport. Atrazine and chlorpyrifos half-life values determined prior to simulating rainfall from corresponding concentrations in the 0-1 cm soil layer were 30 and 10 d. Atrazine, chlorpyrifos, and 2,4-D concentrations remaining i
