| In India, National Thermal Power Plant run more than 70 thermal power plant and subsequently generate about 110 million tonnes of coal-ash and this is predicted to increase up to 170 million tonnes per annum by the year 2012. Fly ash from power generation can be considered either as a waste or as a resource yet to be fully utilized. Huge amounts of fly ash are deposited in adjoining area of the Thermal power plants. These barren fly ash dykes create varied kinds of environmental hazards due to erosion and leachate generation and health hazards to the nearby inhabitants. The present review is focused on application of Lignite fly ash in agriculture. The present review deals with the following topics: Significance of lignite fly ash, Beneficial effects of lignite fly ash, Effect of lignite fly ash on crop growth and yield and Combined effect of lignite fly ash with manures in crop production. |
