| Popis: | Buffer length (0, 2.4, and 4.9 m), mowing height (1.3 and 3.8 cm), and solid-tine aerification were evaluated to reduce pesticide and nutrient runoff from bermudagrass [Cynodon dactylon (L.) Pers.] turf on a Kirkland silt loam (fine, mixed, thermic Udertic Paleustolls) with a 6% slope. Nitrogen, P, chlorpyrifos [o,o-diethyl o-(3,5,6-trichloro-2-pyridinyl) phosphorothioate], and the dimethylamine salts of 2,4-D (2,4-dichlorophenoxyacetic acid), mecoprop [2-(2-methyl-4-chlorophenoxy) propionic acid], and dicamba (3,6-dichloro-o-anisic acid) were applied at standard use rates on plots located upslope of buffers. A portable rainfall simulator applied precipitation rates of 51 or 64 mm h -1 for 75 to 140 min within 24 h after chemical application. Soil moisture before simulated rainfall in July 1995 was low and pesticide and nutrient loss to surface runoff was |
