Description: Atrazine dissplacement was studied in a soll profile as function of water movement and time after herbicide application, taldng into account possible influences of preferential flow on keaching. The experiment consisted of two 7 x 7 m plots of a dark red latosol (Kanduidalfic Eutrudox), located at Pirecicaba, SP, Brazil (22o43'S and 47o25'W), 250 km inside continent, at an altitude of 580 m. One plot was previously treated with 1,000 kg/ha of lime, in order to increase saturation to 88%, and 500 kg/ha of gypsum. Each plot was instrumented with tensiometers, neutron probe acess tubes and soil solution extractors, in order to monitor water and atrazine flows. Atrazine was applied at the high rate of 6 kg/ha of active principllle. Results showed intensiive leaching of atrazine in the whole soil profile, up to the instrumented depth of 150 cm, alredy at the first sampling, seven days after herbicide application. The limed plot showed much higher atrazine leachinng losses than the other plot. The atrazine adsorption capacity of the soll is very low, its maximum value being of the order of 10%, for the 0-15 cm surface layer.
