Civil and Environmental Engineering Faculty Publications

A field lysimeter experiment was conducted during the summers of 1993 and 1994, at the River Laboratory, Utah State University, Logan, Utah. The intent was to study the fate and disposition of metolachlor and 2,4-D in a one dimensional soil system. Metolachlor was applied to corn and 2,4-D was applied to turf. The mobility, persistence, and degradation of these herbicides were investigated in the field lysimeters using four irrigation treatment levels on corn and two irrigation levels on turf. The four irrigation levels applied to corn were 0, 30, 60, and 120 percent of potential evapotranspiration. The two irrigation levels …
