To enhance ecofriendly bulk utilization of Coal fly Ash(CFA) & to generate general acceptability towards this waste material along with other waste materials (water hyacinth/cow dung + grass cuttings) as input material in agriculture & related fields, the reported studies have been carried out selecting nine plants under climatic conditions in & around Kota city applying scientifically designed methods. Results are reported in the form of dose range highlighting positive outcome. The original thesis has been revised. Addition of CFA with soil alters its physical & chemical properties. By variation in applied proportion of bio modified ash desirable results can be obtained. The aim of the experiments was to find out most suitable conditions for initiating a reaction between the constituents of soil & CFA to upgrade the quality of soil to make it more suitable for cultivation of selected plants. It comprises details of physicochemical studies on application of biomodified CFA with organic wastes in the cultivation of selected nine plants. Present study provides a more economic method for the correction of top soil utilizing another waste, that is biomass waste.
