ABSTRACT

 

Fly-Ash (FA) a coal combustion residue of thermal power plants has been regarded as a problematic solid waste all over the world. Disposal of high amount of fly-ash from thermal power plants absorbs huge amount of water, energy and land area by ash ponds. However, several studies proposed that FA can be used as a soil ameliorate that may improve physical and chemical properties of the degraded soils and can be used as a source of readily available plant micro-and macro- nutrients. The high concentration of elements (K, Na, Zn, Ca, Mg and Fe) in fly-ash improves the nutrition for agricultural crops. But the use of fly-ash in agriculture is limited compare to other sector. Review of many studies of last four decades, which systematically covers the importance, scope and apprehension regarding utilization of fly-ash in agriculture. This study also identifies some areas, like soil fertility and its response on cereal oil seed and vegetable crops. Agricultural lime application contributes to global warming as Intergovernmental Panel on Climate Change (IPCC) assumes that all the carbon in agricultural lime is finally released as CO 2 to the atmosphere. It is expected that use of fly-ash instead of lime in agriculture can reduce net CO2 emission and also reduce global warming at some extent.
