Physiological changes and phytoremediation ability of Moringa oleifera growing in polluted soil with Zn and Co heavy metals

Abstract

Extensive environment pollution by explosives and heavy metals caused bymanufacturing, disposal and testing of munitions becomes an issue of increasing concern. Accordingly, this study attempted to examine the effect of phytoremediation of Moringa oleifera on soil polluted with heavy metals. It was performedat College of Agriculture, Tikrit University, from Autumn 2018 to Summer 2019. One type of soil was used, taken from Al-Mahzam city in Salah Al-Din governorate. It concluded that Moringa oleifera showed a great tolerance to the heavy metals (Zn and Co) found in soil and had a good phytoremediation effect. The physiological parameters were represented by (N, P, K, C, protein) and Chlorophyll A+B to obtain better results.
