Fly ash the waste product from thermal power plant is used as a soil amendment along with bacterial cultures which supports plant growth by increasing the soil fertility by providing micro and macronutrients to cultivated crops. Fly ash also improves permeability status of soil and soil texture. The results of this study indicate that fly ash could be beneficial to typical plant growth if it is applied to an adequate rate and to an acceptable medium along with bacterial culture.
