College Kota, University of Kota,(Rajasthan,India) P.G. Department of Botany, Govt.College,Kota-324001(India) Abstract The objective of the study is to investigate physical, chemical, and mineralogical characteristics of fly ash for their potential utilization in agriculture field to reduce use of harmful chemical fertilizers for crop production, The study was conducted with Fly ash of Kota thermal power station, Kota Rajasthan, India. Chemical analysis of fly ash expose that Fly ash is enrich source of many soil vital elements .Fly ash is a byproduct of coal burning in thermal power station. It is a tricky waste residue which create major problems through out the world. Destruction of high amount of thermal byproduct consume a large amount of water, energy and land area and causes many harmful environmental problems , now environmental awareness move towards the proper utilization and management of Fly Ash . However Fly ash is good source of many soil health nutrients, due to its nutritional value it can be used as a supplement of soil health that may improve physical, chemical and biological essence of the soil. The study to improve soil fertility and its productivity with Fly ash amendment was established by pot experiment with monocot and dicot crops ,to reduce the use of harmful chemical fertilizers in agriculture. The work was carried out with an eco-friendly manner. It also reduce the problem of its disposal. Amendment of Fly ash in soil enrich its nutritional value and increase productivity of the selected crop pants. It was found by experiment that amendment of Fly ash up to 70 % and up to 80% increases productivity, but further more amendment decreases growth and productivity of the selected crop plants .Fly-ash has illustrious potential to excel soil fertility and it’s productivity . The high concentration of micro nutrients(Cu, Fe, Zn) and macro nutrients (K, Na, Zn, Ca, Mg and Fe) in fly-ash can improve the productivity of monocot plant Wheat (Triticum aestivum L.) and Dicot plant Soybean (Glycine max L.).
