Sorption and mobility of dimethenamid in a volcanic soil amended with liquid cow manure

This work studied the sorption and mobility of dimethenamid (2-chloro-N-(2,4-dimethyl-3-thienyl)-N-(2-methoxy-1-methylethyl)-acetamide) in soil amended with liquid cow manure (LCM) at doses equivalent to 0, 100, 200 and 300 thousand L ha-1 (D0, D100, D200 and D300 respectively). For the batch sorpti...
