چکیده
Abstract To investigate the role of cow dung in soil reclamation and bio assimilation along with accumulation heavy metals earthworm (P. posthuma) (N=900) earthworms were used treatment groups CD-soil mixture different proportion designed. Nonlethal doses lead acetate cadmium chloride added groups. Mature P. posthuma released each experimental pot maintaining favorable conditions. The pH, carbon, nitrogen, phosphorus, exchangeable cations, metal level was evaluated. results indicated that bio-assimilation Pb Cd by significantly (P ˂ 0.01) higher soil-CD treatments compared to control. Highest both observed T1 (Pb = 563.8 mg/kg 42.95 mg/kg). contents 0.05) lowered casting. nutrient concentration final castings all also equally transformed from less or insoluble more soluble available for plants, except carbon which increased CD proportion. It is concluded as organic matter has a positive effect on posthuma.
