[Degradation reactions of a carbamate herbicide, chlorbufam: effect of soil factors].
Kinetics of degradation of chlorbufam is determined in aqueous solution, in aqueous solution with humic acids, argilo-humic complexes, soil and sterile soil. The adsorption is also evaluated in this different fractions. The adsorption process has a protecting effect and the chlorbufam is not chemically degraded when it is adsorbed on organic matter. The biodisponibility is also decreased by adsorption.
