Abstract
Fly ash (FA), the notorious waste product of coal based thermal power plants, known for its ill effects on agricultural land, may now come as an aid for the farming community. Because of its great availability and low cost, further possibility of its usage should be investigated. Fly ash from both coal and lignite- acts as a good carrier for bio pesticides. It is used as a conditioner to arrest soil erosion, and to induce plant resistance against diseases. However, several studies proposed that FA can be used to improve physical, chemical and biological properties of the egraded soils and is a source of easily available and cheaper micro, macro-nutrients for crops. Thus use of flyash is an effective way of utilization of problematic fly-ash waste in a useful manner. In this study, the review covers the sources, merits and applications of fly ash and fly ash based bio pesticides and fertilizers in agriculture.
