ABSTRACT
Bio-formulations with the use of fly ash as a carrier have been found as a very effective, inexpensive, low maintenance and
environmental friendly technique. The biofertilizer and biopesticides produced using fly ash as carrier should be considered
as a valuable resource for use by various agriculture industries and farmers as India is basically an agriculture based country.
Using fly ash as carrier in bioformulations could mitigate the environmental crisis of fly ash disposal to some extent by
increasing its utilization. This paper assesses the performance of fly ash generated from Chandrapura Thermal Power Station
(CTPS) area of Bokaro District by examining the physico-chemical properties. The fly ash of this region has a potential for
growth of leguminous plant in various trials. In our experiment fly ash alone and in combination with lignite and talc was
tested to explore its possible use as carrier for Azotobacter chroococcum (nitrogen fixing bacteria) and Trichoderma viride
(opportunistic avirulent plant symbionts) formulations. The objective of the present study was to develop fly-ash based bioformulation of selected microbes and to evaluate shelf-life of these formulations through cfu count and statistical analysis.
The result showed the decline in cfu count in all the three carrier combination in both the Azotobacter chroococcum and
Trichoderma viride and the shelf life of both the formulations was found to be better at 28±2 0 C when compared to room
temperature. Fly-ash based bio-fertilizer and bio-pesticide formulations showed slightly better results compared to routine
talc or lignite formulations. This paper includes an outline of social and environmental reasons for solid waste utilization,
and explores the idea of use of hazardous waste as an environmental friendly biofertilizers and biopesticides.
Key words: Bioformulations, fly ash, talc, charcoal, Azotobacter chroococcum and Trichoderma viride, ANOVA test.
1. Introduction
Fly-ash is the portion of the coal combustion residue that enters the flue gas stream in power-generating facilities and
consists of many small, glass-like particles ranging in size from 0.01 to 100 μm (Davison et al., 1974). In India, Fly ash
production is 112 million tons in 2005–06 and it is expected to generate about 150–170 million tones of Fly ash per year by
end of the 11th 5-year plan in 2012 (MOEF, 2007). The mineralogical, physical and chemical properties of Fly-ash depend
on the nature of the parent coal, conditions of combustion, type of emission control devices and storage and handling
methods. Physically Fly Ash occurs as very fine particles, having an average diameter of
