A method for estimating leaching properties of pesticides

, : A method for estimating leaching properties of pesticides. Journal of Pesticide Science 5(2): 199-205

A polynomial expression which gives the change in concentration of eluate was derived for a soil column system in which pesticide solution was added at constant concentration. The polynomial was composed of a theoretical plate number P of soil column, adsorption ratio G for the soil, and distance moved by the solution expressed by imaginary plate number n. The curve has an inflexion point ex0ept when G is small or P is unit.
