Abstract General survey of polluted soil at Menoufia governorate was done to discover different cadmium concentrations in different localities and its effect on microbial activities. A pot experiment was conducted to study the impact of AM fungi and bio-straw extract as biological agents against heavy metal contamination that cause destructive effect on plant. The application of AM fungi and bio-straw extract were successful in agriculture and strongly recommended for minimizing the agrochemicals impute and maintaining the environmental balance as possible. The integrated effect of AM fungi and bio-straw extract was also considered. Results obtained from this study could be summarized as follow: General survey of different polluted soil in El-Menoufia governorate: 1. The highest value of cadmium concentration (1.5 mg/kg soil) was observed at draining channel, (Menouf), while the lowest values exhibited with industrial region (Quesna) which recorded 0.03 mg/kg soil. 2. Mycorrhizal colonization rate reached 80% in Trifolium |
