إنجليزي. The adsorption of atrazine in two soi1 profiles with different development, under no-tillage systems was studied: a typical Haplustol, developed on loess, and a typical Argiustol, developed on alluvial material. Adsorption isotherms were made with the technique of "batch equilibrium". The obtained curves corresponded with curves of type C. The data adjusted with the models of Freundlich and linear. The Kf varied between 2.08 and 0.412, whereas the Kd varied between 2.16 and 0.322. The values of 1/n were next to 1. For the Haplusto1 the affinity was decreased with the depth, whereas for the Argiustol the highest affinity was registered in the Bt sub(1).
