Conservation tillage increases water infliltration and requires higher herbicide rates which could lead to enhanced chemical transport to ground water. Recent studies on conventional and reduced or non-tillage systems as affecting pesticide leaching report contradictory results. Some studies report higher leaching for diverse herbicides from non-tillage (NT) than from conventional tillage (CT) systems due to preferential flow through macropores more abundant in NT than in CT (Isensee et al. 1990 and Gaston and Locke, 1996). Other studies report just the contrary and suggest enhanced sorption and degradation processes in NT could attenuate herbicide leaching (Levanon et al. 1993; Dao, 1995; Fermanich et al., 1996). The purpose of this study was to assess the influence of two tillage systems, conventional tillage (CT) and reduced tillage (RT), on the mobility of the herbicides clopyralid and metamitron in undisturbed soil columns, and to compare these results with those obtained in handpacked soil columns.
