In India about 60-75% of total bituminous coal and 90% of lignite are likely to be utilized in the coming decade of 21st century. Consequently the coal combustion residues (commonly) known as flyash generated would be around 150 million tons/year. Flyash is a ferro-alumino silicate, understood to be greatest nuisance created by burning of coal in thermal power plants. Flyash contains many nutrients for plant growth but numerous studies have shown inconsistent results regarding nutrient concentration in the flyash for utilization of plant growth. The inconsistency observed in plant response and element content is related to the source of flyash, quality of flyash and the nutrient status of the soil or spoil being treated. It has also been tested to be a liming agent and nutrient source in agriculture specially in acidic soils and has also shown to correct nutrient deficiency or increase nutrient uptake by crops. The present paper discusses the nature and possible utilization of Indian flyash in bio-reclamation.
