Abstract
This research examined the effect of mechanical soil disturbance (none or tilled) and legume crop residues (none or hairy vetch) on fluometuron dissipation for 2 yr from the top 0 to 8 cm of soil in a 10 yr field experiment. Soil pH in the upper 0 to 8 cm was ≤ 5.6, and soil organic matter was highest in plots not-tilled and plots which had a vetch cover crop. Calculated initial half-lives of fluometuron ranged from 19 to 38 d in the 2 yr. Neither tillage nor cover crop influenced early-season fluometuron dissipation. However, there were detectable amounts of fluometuron in all treatments 1 yr after application.
