Simulation of concentration effects on mobility and persistence of alachlor

The effect of concentration on mobility and persistence of alachlor was investigated. The investigation was divided into two components: soil column study and model study. In the soil column study, PVC pipe was hand packed to a depth of 30 cm with Catlin silt loam soil. The surface of the soil columns was contaminated with alachlor at rates of 3, 30 and 3000 kg a.i./ha. Columns were then subjected to a simulated rainfall of constant or variable intensity three times during a two month period. Leachate from the columns was collected twice during each rainfall event. Six times during the two months, columns were analyzed to determine pesticide persistence and mobility.
