More than 70% of the world’s energy is generated by coal-based thermal power plants. The coal-based thermal power plants are powered by combustion of bituminous and sub-bituminous coal. During this combustion huge amount of mineral residue is produced known as fly ash. The prevalent practice of disposal of such huge amounts of fly ash in India is to dump it in lagoons, ponds, semi-agriculture lands and wastelands, which not only requires more than 30,000 hectares of agricultural and forest lands, but also becomes a potential source of metal contamination in surface and ground water, threatening human health. To minimize the hazardous effects of fly ash, large scale utilization of fly ash in different areas is gaining global attention. Efforts are being made to reutilize fly ash for more useful and profitable exploitations and commercial purposes. Because of their ability to provide essential macro and micronutrients to plants for nutrition, fly ash is being considered for amending agricultural soils to improve both chemical and physical properties. A large number of demonstrative trials have been executed by different technological institutes and laboratories at various sites in dispersed locations across the country under varied agro-climatic conditions on a spread of crops, forestry and horticulture species. But according to a number of workers fly ash being rich in trace/heavy metals, long time repeated applications to the soil may result in hyper accumulation of the heavy metals, which may impart toxicity in the soils and hence, in plants. According to them there is a need to take care while applying fly ash in agriculture in view of the fear of much harm in the minds. The AM fungi played most fascinating and key role in the amelioration of toxic effects of heavy metals for hosts in heavy metal contaminated soils. Application of AM fungi as bioremediation agents can be exploited suitably for the management of fly ash. In the present communication researches carried-out till date for fly ash management in agriculture through AM fungi have been reviewed. |
