Abstract
A large fraction of coal extracted from the earth is burnt in thermal power stations. In the combustion process most of the mineral matters in the coal are fused into an fly ash. Fly ash has a great potential for use in agriculture as a provider of major and micro nutrients to plants. Concentrations of some elements in the soil may increase when fly ash is applied to the soil. This paper presents the results on analysis of heavy metals in crops of wheat and paddy grown over last two years on coal ash-applied soils of Bakreswar and Farakka sites as a part of Fly Ash Mission projects on bulk scale utilization of coal ash in agricultural lands by Particle Induced X-ray Emission(PIXE) and Energy Dispersive X-ray Fluorescence(EDXRF) techniques.
