Laboratory experiments conducted to determine the effect of different levels (0, 40, 80, 120 and 160 t/ha) of sludge and liquid (50 per cent diluted and undiluted) sewage on the composition of leachate collected for 90 days from four soils of Tamilnadu revealed a significant effect on nutrient concentration in the leachate. The concentration of various nutrients in the leachate was maximum in treatment with 160 tons sludge/ha. Water leaching caused a slight increase in the concentration of these irons in the leachate fractions.
