Abstract (AB)	The Freundlich isothermal relationship is used to show adsorption of Diuron and Neburon in soil. Using algae as test organisms, and a given soil-water ratio, five times more Neburon than Diuron are adsorbed by one gram of soil. The doses of Diuron required to produce 50 per cent inhibition of growth of oats and algae decreases with increasing soil depth. Same amounts of herbicide are more toxic in subsoil layers than in the top soil with a higher organic carbon content.
