A pot experiment was conducted to study the effect of sludge application on metal uptake and biological properties of soil by basmati rice (Oryza sativa, var Pusa Basmati 1121) grown on alkaline soil of IARI farm. In this study, the sludge was collected from Okhla sewage treatment plant, South Delhi. Sludge was added @ 0, 40, 80, 120, 160, and 200 g per pot of soil, which are equivalent to field application of 0, 20, 40, 60, 80, and 100 t ha-1. All six treatments were replicated thrice and experiments were laid out in completely randomised design. The result shows that all the biological properties viz. acid phosphatase, alkaline phosphatase and fluorescein diacetate activity (FDA) were increased for all sludge treated pots over control. Therefore, results can be concluded as sludge is a good source of plant nutrients, nitrogen (N), phosphorus (P), potassium (K), sulphur (S) and two important micronutrients i.e. of zinc (Zn) and iron (Fe) and also helps in improvement in fertility and important biological properties of soil.
