Asit Kumar Behera, Dr. Aliva Patnaik

Abstract :

<p> Phosphogypsum (PG) is one of the by–product of DI–Ammonium Phosphate (DAP) fertilizer plants and its chemical and physical composition hammer over soil biota in a great extent. Prime goal of this investigation was to observe and determine the impact of PG on growth of earthworm Perionyx excavatus. Two forms of PG used for the impact analysis on Perionyx excavates growth i.e solid and soluble form. It was observed in the impact that growth of earthworms decreases with increase of PG dose concentration and exposure period perticulaIly in soluble form although both type of PG found effective. It may due to leaching effect. Soluble form of PG proved lethal as all the population of Perionyx found dead after 30 days of exposure.</p>
