Fly-ash is a resultant of the combustion of coal at high temperature, which is considered as one of the hazardous solid wastes from different thermal power stations all over the world. To minimize the extent of pollution in the physical environment, fly-ash is used as a better amending material to protect soil erosion that leads to improved vegetation. Statistical method is a time-saving as well as cost-effective tool to estimate the physico-chemical properties of fly-ash to increase its agronomic advantage in economically developing countries. The collected data on 7 properties viz. moisture (M), specific gravity (SG), bulk-density (BD), porosity (Ps), water-holding capacity (WHC), pH and electrical conductivity (EC) are subjected to steady state approach of statistical analysis to establish regression equations between significantly correlated properties. Average error percentage between the observed and predicted data indicates the usefulness of the fly-ash.
