Abstract
The variation in adsorption and degradation of fluometuron was determined in soil collected from different depths (0-120 cm) of a Beulah silt loam soil profile. Microbial demethylation was the initial degradation step in both surface and subsurface soils, resulting in accumulations of demethylfluometuron (DMFM). After addition of 1500 ng/g of soil of fluometuron, degradation was adequately described by first-order kinetics. However, these kinetics did not describe degradation after addition of 85 ng/g of soil of [ 14 C-trifluoromethyl]fluometuron
