Fly ash (FA) from NALCO, Odisha (India) was used for amending soil at levels equivalent to 0, 5, 10, 20 40 and 80 T/H in which, tomato was grown and elemental residues of amended soil and plant were enumerated. In the present experiment Azosprillum mixed with graded levels of FA (5, 10, 20 40 and 80 T/H) to observe the role of Azosprillum in improving soil quality and reducing metal toxicity. FA amendments caused significant improvement in soil quality and germination percentage of tomato plants. Growth (seedling height, Shoot length, leaf number) and yield (number of fruits, fruit weight and fruits per plant) of tomato increased with an increase in FA amendments. In the present study fly ash neutralize the pH imbalance, increased EC, CEC, OC, P and some essential and nonessential micro elements i.e. Fe, Mn, Pb, Co and K. Further Azosprillum supplementations caused invariably increments in each growth parameters. The levels of 20 and 40 T/H FA were ideal for fruit yield. FA+ Azosprillum reduced heavy metal concentrations in both soil and plant. Hence, addition of bacterial species to FA may help in reducing the possible heavy metal toxicity of crop plants and can be used for solid waste management in Agro ecosystem.
