ScienceDaily (Feb. 11, 2009) — Grass filter strips placed in riparian zones not only curb soil erosion, but can help block and degrade the widely used herbicide atrazine, Agricultural Research Service (ARS) scientists report.
Atrazine has been used extensively to suppress weeds in corn production for decades, but because it's applied directly to soil it's especially prone to losses in surface runoff. The contamination of surface water by atrazine and its less-toxic breakdown components has raised ecological concerns.
