Abstract

Coal combustion residues are generated in huge amount by more than 120 existing thermal power stations in India. Disposal of fly ash is a great challenge before the thermal power station management. Coal combustion residues can be a good option and can be widely used in agriculture applications in bulk. In the present work a study on macro-nutrients and bio-available micro-nutrients has been carried out. The aim of the study is to assess the suitability of coal combustion residues as fertilizer for agriculture use. Such use will definitely help in utilizing the waste as a resource material in bulk and will also be useful in reducing the environmental impact of coal combustion residues generation to some extent. The methodology of the study includes the determination of available NPK and bio-available (DTPA) extractable elements such as Fe, Cu, Mn, Zn, Pb, Ni, Cr, Cd, and Co. The nutrient status of the coal combustion residue was determined using DTPA extraction method. Available Nitrogen (N) was determined by the Kjeldhal extraction and titration technique, available phosphorous (P) by Olsen's method and available potassium (K) by ammonium acetate method. From the experimental study it was found that coal combustion residue under study is a good source of NPK and bio-available (DTPA) extractable elements and as such it has the potential for use in agricultural sector. Abandoned surface mines devoid of necessary nutrients can be revegetated using coal combustion residues. This study covers parameters like pH, electrical conductivity, CCE, Organic Carbon, and CaCO3 (%).
